New HDD rockstar enters the Australasian stage

TRACTO, a leading trenchless technology manufacturer, is launching its new 20ACS in Australia and New Zealand at this year’s No-Dig Down Under.

German manufacturer of trenchless technology solutions, TRACTO, is renowned for its innovative, highquality no-dig solutions. Over the decades, the company has consistently advanced no-dig technology, particularly in horizontal directional drilling (HDD) with steerable drilling rigs.

The latest development in the company’s range of all condition systems is the GRUNDODRILL 20ACS. Built off the foundations of the revolutionary 18ACS, the new 20 tonne HDD rock drill is equipped with a range of technical and engineering enhancements, making it ideally suited to the unique challenges facing local drilling contractors. Following its debut as the successor to the King of Rock 18ACS at bauma 2025, the company’s local subsidiary, TRACTO Australia, will launch the new ‘rockstar’ at No-Dig Down Under.

Evolution of rock drilling

HDD is one of the most versatile and flexible trenchless methods, but is also technically demanding. TRACTO was the first German company to explore underground drilling control in the 1970s, launching the first steerable drilling rigs from a pit by the late 1980s.

These early HDD systems featured a percussion mechanism, which would later become a defining feature of GRUNDODRILL rigs.

Since then, successive generations have become more powerful, efficient and aligned with evolving technical standards and user needs. A key milestone was the 18ACS all condition system, which was the first machine that facilitated jet and rock drilling with a single rig.

One of the greatest challenges in HDD rock drilling lies in navigating mixed or

complex ground conditions. Unlike uniform soil, variable layers demand far more from the equipment.

TRACTO addressed this with the GRUNDODRILL 18ACS, featuring a flexible drill rod concept. This system uses standard rods for jet drilling and ELICON twin-tube rods with a rock drill head (roller chisel or PDC bit) for more challenging geological conditions.

The twin-tube design allows the inner rod to drive the drill head while the outer rod steers it, reducing wear and ensuring optimal flushing over long distances. As a result, less bentonite is required, lowering the costs of purchasing, processing and disposal.

Incorporating a fully automatic rod handling system, the 18ACS offered reduced downtime and greater operator ease. Its advanced design, with stepless torque and speed adjustment and no power loss, helped establish the ‘King of

Rock’ as TRACTO’s most successful rock rig, used in complex geologies around the world. This scalable rod system has since been adopted in the latest generation of JCS/ ACS equipment, including the efficient 13 tonne ACS130 and 30 tonne ACS300 rock drilling rigs

Mastering any terrain

With the GRUNDODRILL 20ACS, TRACTO has responded to increasing demands in HDD rock drilling while staying committed to delivering best-in-class solutions. Built on the foundation of the 18ACS, the 20ACS combines the versatility of rock and jet drilling modes with even greater performance, safety and operator comfort.

Improvements in serviceability, automation and digital integration allow operators more flexibility on site. Increased thrust and pulling force, a refined rod system, and high torque enable the 20ACS to handle complex bores up

to 200m with confidence and efficiency.

The 20ACS delivers 200kN of thrust and pulling force, along with a torque output of 9000Nm on the outer rods and 2500Nm on the inner rods. It features a powerful 400l/min bentonite pump and a 123kW diesel engine with stepless torque adjustment, allowing highperformance drilling across a range of profiles.

The fully automatic system covers drilling, rod changing and lubrication in rock mode, reducing operational time and simplifying handling. The rig is also convertible for cableguided bores using ELICON rods, ideal for challenging conditions and deep installations.

Its rod capacity has been increased, carrying up to 144m of ELICON DL101 twin-tube rods on board. Operators can easily select from multiple rod types via the operating menu and switch between them without needing a service technician, while jet drilling with the inner rods remains seamless.

Safety and operator comfort have also

been enhanced. The undercarriage offers a secure setup in difficult terrain, while optional features such as two support plates and an anchor drilling rig with improved auger profiles ensure maximum stability during demanding operations.

A steep inclination angle allows minimal setback in confined areas, and an automatic lubrication system further supports reliable performance.

The 20ACS can be driven and operated via radio remote control, and the swivel cabin has been upgraded with air conditioning, tinted windows, a heated Grammer comfort seat, expanded storage, USB ports, cup holders and more – maximising ergonomics and comfort on site.

Drilling data is easily recorded using the BORE DATA app and can be retrieved via cloud or USB connection. Additionally, the rig integrates freely with the COMMANDER fleet management app, allowing real-time tracking of rig location, performance and consumption.

TRACTO Australia sales manager Dan Toms said these enhancements, combined with the manufacturer’s reputation for robust engineering, make the GRUNDODRILL 20ACS ideally suited to Australia and New Zealand’s complex geologies.

“We were at bauma earlier this year to see the launch of the 20ACS and have been lucky enough to see the machine perform in the field,” he said.

“It delivers a powerful, efficient solution for demanding trenchless projects. We can’t wait to start delivering them to Australasian contractors and seeing them perform in local conditions.”

TRACTO Australia provides more than just equipment, with the local team offering expert advice, training, and tailored solutions to meet the unique demands of Australian contractors. This extends to guidance on financing options when purchasing a new rig, to hands-on training and service support.

Toms said the company – supported by the factory in Germany – was committed to helping customers maximise the success of their trenchless projects.

“Delivering the machine to the client is the first step in a partnership that can last decades,” he said.

“We pride ourselves on supporting the end user for the lifetime of the product, as well as being available for any training, spare parts or any other after sales support. While the 20ACS is a brand new machine, nothing changes in terms of the value we have been adding to local contractors since we setup in Australia almost three decades ago.

“We invite all delegates and visitors to No-Dig Down Under to stop by and see us at stand D14, check out the new machine and have a chat with how we can partner with you to take your drilling to the next level.”

Jacking and laying debut on the global scale for CRCHI

As CRCHI prepares for its first visit as a No-Dig Down Under exhibitor, it has looked back on its finest recent works.

On 28 October 2024 in Thailand, CRCHI’s ZTP1020 jackingand-laying machine achieved a significant engineering milestone, completing a 1046m single-pass pipeline installation in southern Bangkok.

This performance marked the global debut of CRCHI’s custom trenchless equipment and demonstrated the company’s ability to meet complex underground construction demands outside of China.

The 1046m crossing is part of the Bang Pakong–South Bangkok power plant transmission pipeline project Phase 1 (BSPP1), a strategic 33.9km natural gas pipeline connecting the eastern seaboard with a 2400MW power station serving Bangkok and surrounding provinces.

The project is notable for being the world’s first 36-inch continuous jacking-and-laying construction, where trenchless methods account for 90 per cent of the total length.

The pipeline includes 26km of long-distance jacking across clay and intertidal sediment, 4km of horizontal directional drilling (HDD), 0.4km of pipe-jacked crossings, and 3.5km of open-cut tie-ins. With demanding geological conditions and tight urban infrastructure, traditional methods alone weren’t sufficient –necessitating innovation.

The alignment cut through shrimp ponds, urban residential zones, and high-voltage power corridors. It ran parallel to live gas lines and navigates between high-voltage

transmission towers spaced just 3.5m apart with 200m intervals. Excavation in this zone required needle-threading precision, stable propulsion, and absolute reliability from the guidance system.

Typical HDD methods would face a high risk of borehole collapse in the soft clay, while traditional pipe-jacking requires sequential pipe installation, limiting efficiency. The contractor, CPP – responsible for 60 per cent of Thailand’s pipeline infrastructure – chose an alternative: a hybrid jacking-and-laying method.

This innovative method retains the straightline flexibility of directional drilling while incorporating integrated excavation and spoil removal similar to conventional pipe-jacking. CRCHI customized and delivered the machine to meet the project’s specific requirements, enabling it to execute long-distance, curved drives in varying ground conditions with increased accuracy and speed.

Custom-engineered for global performance

The ZTP1020 was one of five machines used on the project and the only one developed specifically for international delivery. CRCHI designed it for nine separate drives totalling 7681m, including the record-breaking 1046m section. These drives involved complex S-shaped horizontal curves (1200m radius) and V-shaped vertical curves with entry inclines of 4–6° and exits up to 9°.

With a 1050mm excavation diameter and

640kW of installed power, the ZTP1020 features a hydrostatic elevation system and a hybrid inertial navigation platform capable of centimetre-level accuracy. It can climb longitudinal gradients of plus or minus 15° and turn along a 1200m radius curve – ideal for constrained urban and industrial alignments.

The equipment package included a 500-tonne pipe thruster, pipe-jacking machine, remote control, inertial guidance and steering correction system, lubrication and grouting systems, slurry circulation and separation systems, as well as full power and hydraulic support. Despite the complexity, CRCHI delivered the complete system from its Changsha facility in just 98 days.

Launched in December 2023, the ZTP1020 began working through nine pipeline sections with high consistency. It achieved an average excavation speed of 600mm/min, reaching 650mm/min at peak. Across its drives, it achieved multiple milestones, such as a maximum single-shift advance of 202m, hourly progress of 32m, and a top speed of 48m in two hours.

In the second section – a tight 840m stretch between five high-voltage towers –11 pipe sections of 78m each were laid at full speed in just 15 days. Despite working in a silty clay layer with low stability, the equipment maintained speed and directional control throughout.

The sixth section saw the machine complete a full 1046m pass, setting a record for single-

pass installation of a 36-inch pipe in this type of strata. Accuracy remained within 10cm throughout the drive, further validating the reliability of the system’s guidance and control.

While CRCHI is already well-established in China’s infrastructure sector, the successful performance of the ZTP1020 in Thailand marks a critical milestone in its global strategy, particularly as it prepares to enter the Australian market. This project showcased CRCHI’s ability to rapidly engineer, deliver, and support custom

MainLite 2 fit and MicroGator Air 150

• for pipe diameters starting at DN150

• can be operated with MainLite system

equipment for international trenchless projects under demanding conditions.

The company deployed a full-service team on site, ensuring rapid assembly and commissioning in under a month. The machine recorded a zero-failure rate throughout operations, further affirming its readiness for broader deployment in the AsiaPacific region.

With this breakthrough, CRCHI has proven that its trenchless equipment can deliver

precision, speed, and reliability in high-risk, high-value environments.

As CRCHI looks to bring this technology to Australia, the success in Thailand stands as a compelling case for local utilities, contractors, and infrastructure authorities looking for advanced, cost-effective, and resilient trenchless solutions.

Major works out west

is carrying out the crucial construction of a new sewer main extension in Kalgoorlie, Western Australia.

In February 2025, Rob Carr was awarded the contract for the construction of the DN600, DN375, and DN225 sewer main extension project by the City of Kalgoorlie.

This project involves the construction of 2340m of sewer infrastructure, which is essential for supporting the expansion of both residential housing and industrial areas in Kalgoorlie – a key contributor to Western Australia’s economy.

The scope of work for this project includes the installation of various pipe sizes through tunnelling methods.

Specifically, the project involves the tunnelling installation of 377m of DN375 glass reinforced plastic (GRP) pipe and 61m of DN300 reinforced concrete (RC) pipe.

In addition to tunnelling, the project includes several open trench installations, including 528m of DN600 GRP pipe and 1374m of DN375 PVC pipe.

The works also involve the construction of 17 polyethylene access chambers, each up to 6m deep, as well as nine precast concrete access chambers of similar depth.

Furthermore, four in situ concrete access chambers are being constructed on existing sewers.

The project also includes making connections to the existing DN600 and DN375 sewer lines.

To carry out the tunnelling works, Rob Carr is using its fleet of Iseki tunnel boring machines, with the longest tunnelling drive extending to 150m.

Slurry pressure balanced micro tunnelling was selected in lieu of other techniques due to the crossings and proximity of Gatacre Road, a main road servicing Kalgoorlie Airport. The remaining areas of the project can be constructed utilising open trench pipe laying.

The geotechnical conditions

The geotechnical conditions expected were a mix of rock and clay.

There were limitations on the geotechnical investigation that could be undertaken during the design stage due to the proximity to the Kalgoorlie Airport.

As a result, following award of the project, Rob Carr undertook a geophysical survey of microtunnelled sections. The data received identified the rock interface and enabled selection of either a rock or clay head for the different microtunnelled sections to ensure successful completion of the drives.

Works commenced on 25 March 2025, with the required date of completion in February 2026.

To date, the Rob Carr team has completed three of the five microtunnelled sections (257m) and 1098m of DN375 pipe laying.

Rob Carr General Manager Angelo Soumboulidis said that complex projects are where the company truly excels.

“Navigating tough geological conditions, rail and road crossings, and critical infrastructure connections requires not only technical precision, but also resilience and adaptability,” he said.

“Our team’s expertise and dedication ensures that whatever project we take on will be executed with the highest of standards, delivering a seamless outcome for our clients.”

Rob Carr operates under the group mantra of ‘green is great’ and has adopted this goal as its own, to keep Australia beautiful for now and sustainable for future generations.

The company has a strong commitment to

the environment and the impact it has locally in planning and execution of projects.

In addition to its environmental consciousness, Rob Carr is highly experienced in complex civil construction works and is able to offer more complete service to its partners and clients.

The company’s capacity for delivering complex infrastructure projects without compromising the environment is further demonstrated through its involvement in building essential facilities such as pump stations, including mechanical and electrical fit-out, and storage tanks.

These capabilities make Rob Carr a full-service contractor capable of delivering comprehensive and sustainable infrastructure solutions throughout Australia and New Zealand.

Weathering the storm with quality liners

Tackling severe stormwater infiltration, Clearflo Specialised Services deployed SAERTEXLINER and Rausch RRcure 100 SE for a critical TAFE Queensland infrastructure upgrade.

SAERTEX-LINER MULTI Type S+.

Amajor stormwater rehabilitation at TAFE Queensland Eagle Farm Campus saw Clearflo Specialised Services overcome extreme root and concrete infiltration using advanced trenchless technology from SAERTEX multiCom® and Rausch Rehab, delivering a long-term structural solution with minimal disruption.

This was one of the first stormwater rehabilitation projects in Queensland to use the SAERTEX-LINER® MULTI Type S+ Standard in combination with the Rausch RRcure 100 SE UV system, technologies available in Australia and New Zealand.

When Clearflo Specialised Services was awarded the contract to rehabilitate 450m of deteriorated stormwater pipe at TAFE Queensland Eagle Farm Campus in Brisbane, the crew faced some of the worst root and concrete infiltration they had ever encountered. With support from Pipe Core and access to innovative technology from Rausch Rehab

and SAERTEX multiCom, Clearflo Specialised Services delivered a structural renewal solution which the manufacturer said has a technical service life of 100 years, setting a new benchmark for trenchless rehabilitation in complex high-traffic sites.

The site, located in Brisbane’s eastern industrial hub of Eagle Farm, was experiencing major stormwater blockages. More than 90 per cent of the pipe network was obstructed, choked by invasive roots from large Moreton Bay Fig trees along with severe concrete in the lines.

Clearflo Specialised Services Owner John Farrugia said he had never seen such severe infiltration.

“We had over 200m of tree roots to cut before we could even clean the line properly,” he said.

To overcome the challenge, Clearflo Specialised Services engaged TDG Environmental, an experienced specialist in

asset investigations, renewals, and maintenance. They conducted high-pressure robotic cutting and ultra-high-pressure water jetting to clear the obstacles. Once the area was cleared, the relining program could begin, carefully staged to maintain access and minimise disruption to operations for TAFE Queensland.

Throughout the project, Clearflo Specialised Services maintained close communication with TAFE Queensland facilities staff, who commended the crew’s professionalism, safety protocols, and ability to keep the site accessible during term time. Temporary fencing was erected around access chambers and pedestrian paths to ensure safety.

Over a four-week period, the crew rehabilitated multiple sections of pipe, relining one lane at a time. Conduit lengths ranged from 15–68m, with diameters from DN150–300. The crew also completed multiple junction reinstatements and relined over 100m of DN450 mains using SAERTEX-LINER

MULTI Type S+ Standard, a glass-reinforced liner from SAERTEX multiCom, cured using the Rausch RRcure 100 SE UV system.

The liner was chosen for its long technical service life – which SAERTEX has independently tested to 100 years – structural performance, and thin wall thickness, making it an ideal match for confined spaces and approved for use in Queensland.

“SAERTEX multiCom has been great to work with,” Farrugia said. “Their team is upfront about what the product can and can’t do. That transparency helps avoid project risk and builds trust.”

To support the project, Clearflo Specialised Services invested in the Rausch RRcure 100 SE, a self-contained UV curing system available through Pipe Core. Designed for diameters between DN150 and DN1000, it’s well-suited to access-limited sites like schools and carparks.

“The size of the RRcure 100 SE is what appealed to us,” Farrugia said. “It fits into tight spaces. We’ve now completed eight jobs with it, and this TAFE Queensland project was the first time it was used consistently across four weeks.”

To streamline operations, Clearflo Specialised Services custom-built a van with a ramp to house the curing system, enabling quick and safe deployment on site.

Founded in 2000, Clearflow Specialised Services has grown into a multi-vehicle operation. The crew has continually invested in training and upskilling to ensure operational confidence and system reliability.

“We sent a crew member to Germany for hands-on training with the Rausch Rehab system,” Farrugia said.

This project also supported workforce development, with a Queensland-based crew

completing certified theoretical and practical training in SAERTEX-LINER® installation method for both gravity and pressure pipe systems

“Knowledge is power,” said Farrugia. “The more we understand the system, whether it’s fault finding, terminations, or diagnostics, the less downtime we have and the less frustration for the crew.”

“The ability to access global expertise combined with local support has been a key part of the project’s success. Having that level of support available has been invaluable. The industry is moving forward thanks to this kind of innovation and collaboration.”

Project benefits included:

• Long-term durability with an expected technical service life of 100 years

• Trenchless installation with minimal community disruption

• Improved flow capacity of stormwater network

• Fast, efficient, UV-cured liner installation

• Compact equipment easy to use in restricted areas

• Ef ficient scheduling with reduced site downtime

• Lo cal upskilling and capability development

Despite the intensive preparation required to clear the stormwater lines, the project was delivered on time and within budget. Most importantly, it future-proofed a critical asset in Brisbane’s stormwater infrastructure, ensuring the site is compliant and ready for redevelopment.

Treading new ground

Michels Trenchless is using an emerging, specialised trenchless construction technology to build the critical shore approaches essential to connecting offshore transmission lines to onshore power grids.

As Australia accelerates development of offshore wind projects as part of the country’s strategy to decarbonise its energy sector, Michels is bringing to Australia the engineering and construction experience it developed on some of the largest offshore wind projects in the United States.

Although horizontal directional drilling (HDD) is often the go-to method for shore approaches, Michels has found that the Direct Pipe® installation method can be very effective in certain situations. Particularly well-suited for areas with challenging ground conditions, such as mixed soils, high groundwater levels, or unstable geology, Direct Pipe combines a steerable microtunnel boring machine and a powerful thruster to install a pipeline on an accurate alignment and grade. With closed-face excavation and a continuously supported borehole, Direct Pipe is effective for long, large-diameter pipeline installations with minimal environmental impact.

A recently completed project in the United States demonstrated how trenchless construction methods can be combined to

construct landfalls and trenchless crossings; in this case, electrical conduits for a 176-turbine (2.6-gigawatt) wind farm located 24 nautical miles off the coast of Virginia.

During design of the Coastal Virginia Offshore Wind projects in Virginia, Michels recommended using Direct Pipe for the nine landfalls, all of which were mined from the beach out into the floor of the Atlantic Ocean. Although HDD would typically be used for the application, Direct Pipe allowed the client to move forward with the project with minimal environmental risk without impacting the capacity of the project. The result was the largest number of Direct Pipe installations completed at one time anywhere in the world. Additionally, ten HDDs were performed to cross sensitive areas on land to install electrical conduits to house the new power cables.

The nine Direct Pipe landfall installations placed 42-inch-diameter steel casing from the beach to the ocean floor. Then, 36-inch HDPE conduit was pulled inside each steel conduit. Approximately 17,000 feet of HDPE pipe

was placed inside the steel casing between the nine installations. Next, the steel casing was extracted, leaving the HDPE conduit in place. Although it ended successfully, the project was not without challenges. The landfall installation included excavation of the entry pit to set up the Direct Pipe equipment. When Michels started the excavation for construction of the entry pit, it was discovered that the water table was approximately seven feet higher than previously anticipated. This led to a change in the dewatering method. Additionally, the test on the groundwater revealed the presence of per- and polyfluoroalkyl substances (PFAS).

The project team resolved the issue by building an on-site water treatment plant to treat the groundwater before disposal. While this led to additional project cost and impacts on the schedule, the project team was able to make up time by completing the landfall installations in shorter durations than scheduled.

Engineering a generational legacy

Trenchless Australasia sat down with Interflow to discuss the company’s new sustainability framework, and how it is leaving a better legacy for future generations.

Interflow Sustainability and Environment

Manager Pam Johnson and her colleagues have been communicating the new sustainability framework and plans across all levels within the company. Johnson has become increasingly aware of the importance of bringing the framework to life for individuals, their families and for the communities in which they live and work.

“While aligning with the United Nations Sustainable Development Goals (UN SDGs) provides important direction for Interflow, it is easy to feel that they are disconnected from our day-to-day decisions,” she said.

“But practical examples bring them to life. For instance, we know if sediment or pollutants are discharged into a stormwater drain, that directly relates to SDG 14: Life Below Water, which focuses on protecting aquatic ecosystems from pollution.

“It’s important to remember that our work is directly connected to real-world environmental impacts. In this same example, discharging pollutants into a waterway will contribute to degraded ecosystems, impacting

our local communities. Applying the SDG framework is all very relevant for governments and for industry, but it’s also very relevant for individuals and communities.”

When Johnson joined Interflow, she recognised that some good foundations had already been established to drive meaningful and positive sustainability outcomes.

What the organisation required was structure, clarity and momentum.

That’s what the sustainability framework delivers. It’s a live document that will be updated regularly to reflect changing regulations, stakeholder input and expectations, technological shifts and evolving best practice. This creates a shared language and understanding across the business, and sets a clear course for the future.

Johnson said sustainability is sometimes mistakenly reduced to just environmental management, particularly in operational or project-based industries. Instead, Interflow’s latest sustainability framework deliberately connects environmental protection, social considerations, governance, ethical practices and economic sustainability together.

While the broad focus of the framework is on the UN SDGs that will help improve global outcomes such as responsible consumption and production and climate action, Johnson and her team are working to translate its pieces into personal, relatable outcomes for all members of the Interflow family.

Interflow’s key areas of sustainability

The framework identifies three main pillars: environmental stewardship, social responsibility, and governance.

From the environmental angle, this means a commitment to net zero greenhouse gas emissions by 2040. Interflow is also committing to using 100 per cent renewable electricity by the end of 2026, and 100 per cent decarbonisation of light vehicles, by the end of 2031.

Less than 20 per cent of the company’s emissions come from operations, with over 80 per cent coming from Interflow’s supply

regional managers, team leaders and business partners to ensure implementation at all levels.

Transparent reporting is a key focus of this, That reporting will be aligned with Australian Sustainability Reporting Standards and moving forward, with the Global Reporting Initiative.

“We need to measure and document what we’re doing and what we’re achieving, so we can continually improve,” Johnson said.

The new sustainability framework is an invitation. It asks all stakeholders to join the organisation on the sustainability journey.

“Sustainability isn’t the responsibility of one person, it needs to be woven into the work of

so many within the business and outside of it,” Johnson said.

“That’s why Interflow’s message is clear: this is a journey we take together.

“This sustainability framework is going to be my handbook – it’s something I can go back to and hold myself, and the organisation, accountable to.

“And as the framework says: as a business we can drive meaningful change, create shared value and improve lives for generations to come.”

A first for the Territory

Driven by a strong local partnership and demand for long-lasting trenchless solutions, Pro Line’s UV-CIPP liner technology delivered over 5km of structural pipe rehabilitation.

Strengthening its presence across remote Australia, Pro Line partnered with leading trenchless contractor Northern Territory Pipe Relining to deliver the NT’s first ever ultraviolet cured-in-place pipe (UVCIPP) installation.

The large-scale rehabilitation involved more than 5000m of sewer pipeline relining across several remote sites, a process that required a combination of precise planning, logistical coordination, and robust trenchless technology.

With limited access, harsh environmental conditions, and minimal allowable downtime, the project demanded a liner system and delivery team that could perform under pressure, a challenge well-matched by Northern Territory Pipe Relining.

As a full-service trenchless rehabilitation provider, the company offers a comprehensive suite of solutions – including CCTV inspection, and no-dig repair methods –positioning itself as a trusted partner for complex pipeline works across the region.

At the heart of the project was Pro Line’s innovative permanent inner foil liner, designed to remain inside the liner after curing. This eliminated the timeconsuming process of removing inner foil postinstallation, a change that

proved especially valuable on a project of this scale; the innovation is estimated to have saved approximately three full working days across the works, streamlining delivery and reducing overall time on site.

The environmental benefits were also significant. By eliminating the need to remove and dispose of inner foil, Pro Line’s design reduced plastic waste generated during installation, a key improvement in the sustainability profile of UV-CIPP relining.

Pro Line is widely recognised as the pioneer of sustainability across the UV-CIPP industry, with demonstrated environmental performance embedded at every level of its operation. This position continues to drive innovation and raise the standard for greener, lower-impact trenchless solutions.

Pro Line Sales and Technical Director Kevin Woolf is excited to bring the innovations to the Australasian market.

“We developed the permanent inner foil system to solve exactly these kinds of challenges – remote access, tight timeframes, and the need for consistency,” he said. “It’s a major innovation that simplifies installation, reduces waste, and improves results.

“This project [in the NT] proved exactly why it’s the right solution for high-stakes work in tough conditions. And it’s why we’re seeing such strong uptake and positive feedback from contractors and asset owners across the market.”

Pro Line has conducted independent testing which found it’s UV-cured glass-reinforced plastic (GRP) liner offers long-term structural rehabilitation with a 100-year service life. The use of the trenchless product eliminates the need for excavation and dramatically reduces future maintenance. It also cures rapidly under UV light, minimising time in the ground and reducing disruption to surrounding infrastructure.

Northern Territory Pipe Relining owner Jay Stuart said the company had to pick a supplier he could really trust.

“Pro Line’s demonstrated experience on complex relining projects showed from the start,” he said. “Their support was hands-on and the liner quality was outstanding.

“The new permanent inner foil saved time on site, and with a 100-year service life we know we’re delivering a long-term solution for our clients.”

This landmark project marks a significant step forward for trenchless technology in the NT, opening the door to faster and more sustainable pipeline rehabilitation.

With further regional projects already in planning, Pro Line’s commitment to innovation and strong delivery partnerships continues to drive outcomes across Australia’s most challenging environments.

Amiblu Australia: New name, unmatched expertise

Australia’s only GRP jacking pipe manufacturer brings global strength and local excellence to No-Dig Down Under.

Amiblu Australia’s manufacturing facility may be based in Adelaide’s south, but it’s ready to travel anywhere for the right job – and the company is making the most of it’s market.

Amiblu’s mission to deliver sustainable and durable water management solutions on a global scale was considerably bolstered with the acquisition of RPC Pipe Systems, its longstanding technology partner for Flowtite pipe systems.

The move has enabled Amiblu to expand its operations into the Asia-Pacific region.

RPC Pipe Systems has been a trusted licensee of Flowtite technology since 2006, playing a critical role in establishing glassreinforced plastic (GRP) as a key material for addressing acute water shortages across Australia and New Zealand.

Now fully under the Amiblu umbrella, Amiblu Pipe Systems’ local manufacturing arm will align even more closely with Amiblu’s mission to combat the world’s water crisis with advanced, long-lasting pipe systems.

Founded as a joint venture in 2017 by Amiantit Europe and Hobas Europe, Amiblu rapidly positioned itself as the global leader in GRP pipe production, leveraging its ownership of Flowtite continuous filament winding and Hobas centrifugal casting technologies.

Amiblu operates the world’s largest fully accredited GRP pipe testing laboratory, located in Norway, and remains committed to innovation, quality and long-term sustainability across its operations.

By integrating RPC Pipe Systems’ technical capabilities and local experience with its own global reach, Amiblu is now better placed to provide effective, value-driven water infrastructure solutions in the face of growing environmental and urbanisation pressures.

Amiblu-owned products have been utilised in countless of Australia and New Zealand’s major construction projects in recent years.

The West Gate Tunnel Project’s North Yarra Main Sewer in Melbourne used 660m of Dn3000 Amiblu HOBAS jacking pipe in works that redirected the sewer to make way for the tunnel. The Elizabeth Street Sewer – one of the most prominent in Melbourne – significantly increased its capacity with 756m of DN800 Amiblu Flowtite jacking pipe, with trenchless technology ensuring minimal disruptions around the city’s busiest tram lines. New Zealand’s largest wastewater

project, the Central Interceptor, used OD3600 Amiblu jacking pipes to allow the tunnel to run for 16.2km under Auckland and the Manukau Harbour.

The sewer line was a small diversion between two maintenance holes, and Amiblu was the only pipe supplier that could manufacture a pipe with the required internal diameter of 3500mm.

With the niche expertise of a local supplier,

in the local market and an opportunity to showcase its unique technology platforms.

“Amiblu is a world-leading technology manufacturer for trenchless pipes. We’ve chosen to exhibit at this year’s conference to bring awareness to who Amiblu is in the market and what our long-term goals are, particularly as the only Australian manufacturer of GRP jacking and relining pipe,” he said.

“We love that this event brings both

to the market and highlighting the innovation behind its suite of trenchless solutions.

For anyone uncertain about attending, Fraraccio’s message is simple.

“If you’re involved in civil infrastructure, you should be at this conference,” he said.

“The trenchless industry is growing, and you might be surprised by how these solutions could fit your construction needs.”

Amiblu will be showcasing its proprietary technologies, including Flowtite continuous filament wound, Hobas centrifugally cast and NC Line filament wound systems.

VTI: Building more than trucks

Trenchless Australasia sat down with Vac Truck Industries to hear how the company is creating trust, safety, and a community of innovators.

In an industry often dominated by competition and complexity, Vac Truck Industries (VTI) has carved out a different kind of legacy; one grounded in purpose, people, and practicality. Founded not to outshine the rest, but to meet real needs with integrity and innovation, VTI has grown into one of Australia’s most trusted original equipment manufacturers of vacuum excavation and liquid waste equipment.

“We never set out to beat everyone else. That was never the goal,” VTI Managing Director Ned Popovic said.

“We built this company on friendship, on a shared desire to improve safety in the industry, and most of all, on a commitment to help people.”

With head office based on the Gold Coast, VTI designs and manufactures Australianmade, high-quality equipment for the civil construction, electrical, infrastructure, mining, drilling, oil, and gas sectors across Australia and New Zealand. In just a few years, the company has rapidly scaled its operations, becoming a key equipment supplier not only across Australia but throughout the broader AsiaPacific region.

Every VTI unit is designed, engineered, and built right here in Australia.

This means equipment is engineered to suit challenging Australian conditions – with fast, local support, ready access to spare parts, and a clear understanding of what operators need on the job.

From hydro excavation vacuum systems (vac trucks), to high-pressure drain cleaning jetters and liquid waste collection trucks (sucker trucks, suction trucks, vacuum suction trucks), VTI delivers purpose-built vehicles across a broad range of volume sizes and power capacities.

“We run a wide range of VTI units, from compact models to larger builds,” one customer said. “No matter what kind of job we’re facing, there’s always a VTI truck that fits the task. That kind of flexibility is a real asset in today’s fast-paced market.”

VTI equipment is known for being simple and practical, with no-fuss controls and solid, reliable performance. Whether you’re a small contractor or managing a large-scale fleet, VTI works closely with each client to customise builds that meet specific job demands –without over-engineering.

From dream to demand

“We saw a gap in the market and we knew we had something to offer. So, we went for it,”

VTI Managing Director Matt Clough said.

“It wasn’t easy. In fact, it took us over three years just to get the business off the ground.”

With perseverance through late nights, tough decisions, and uncertain days, VTI’s vision slowly came to life. Today, the company has outgrown its original facilities three times and delivers a minimum of six custom builds per month.

“We used to dream about the day when we’d be so in demand that we’d have to tell customers, ‘It’ll be a few months before we can even start your build.’ Now, that’s our reality,” Clough said.

While manufacturing excellence sets VTI apart, it’s the company’s ongoing commitment to customer support that defines its reputation. Ready Group is one such customer.

“When you invest in a VTI unit, you’re getting more than just a machine, you’re gaining long-term support,” Ready Group Chief Operations Officer Pascal Beylacq said.

“The parts department is stocked, responsive, and there’s always someone ready to help. And the best part? They don’t forget about you after the sale.”

Cleaner, smarter, more profitable

GN Solids Australia is leading the way to a more environmentally friendly and cost-effective way of working

In trenchless operations, efficiency, cost control and environmental responsibility are more important than ever.

For contractors, hydrovac operators and drilling companies across Australia and the wider Pacific region, GN Solids Australia is offering practical, proven solutions that directly support these goals.

Established in Brisbane in 2023, GN Solids Australia is the local branch of Hebei GN Solids Control, a global manufacturer of industrial separation and solids control equipment.

With warehousing, spare parts, commissioning, servicing and repair and dedicated support available on the ground, the company is now better placed than ever to meet the needs of trenchless professionals across Australia and New Zealand.

One of GN’s standout offerings is its hydro excavation recycling plant, designed specifically to tackle the challenges of slurry disposal.

Instead of relying on costly and timerestricted tipping at waste facilities, hydrovac operators can now process slurry themselves, recovering graded solids and reusable water through a robust multi-stage system.

disposal and cutting overall fluid costs.

The process includes coarse and desilting shakers, screening bars, a decanter centrifuge and a chemical dosing unit.

The recovered solids can be resold to landscapers, construction firms, farms, plumbers and garden suppliers, opening new revenue streams while reducing landfill volumes and water usage.

For waste management facilities, this technology offers a smart way to handle incoming slurry while minimising disposal volumes and maximising recycling outcomes.

The system’s ability to recover clean water and high-quality solids not only supports environmental targets but also enhances operational efficiency for both private operators and councils.

GN’s trenchless support also extends to horizontal drilling and microtunnelling. There are four types of standard mud recycling systems including 200/400/600/1000GPM. The 600GPM mud recycling system, currently in use with trenchless contractors, is a compact and mobile solution for maintaining drilling fluid quality on site.

Equipped with hydraulic jacking-up legs, the unit can be easily loaded or unloaded without the need for crane trucks, making it particularly valuable for contractors working in remote or urban environments. Even without a centrifuge, the system maintains healthy drilling mud, reducing the need for frequent

This technology has been utilised by contractors across Australia and New Zealand, including NSW based Openshore, to streamline its cleaning processes.

By investing in this kind of equipment, contractors can avoid downtime, reduce operating expenses and improve environmental performance.

Hydrovac operators can benefit from processing not only their own slurry, but

also that of others, creating a service and resale opportunity that turns waste into a commercial asset.

With a strong local presence backed by global engineering, GN Solids Australia is helping trenchless operators move forward with smarter, cleaner and more cost-effective solutions built for the realities of today’s work.

Faster than expected

The AdaptX technology has proven its worth in a recent trenchless project in Victoria.

Edge Underground has again demonstrated the disruptive power of innovation, completing a recent microtunnelling project at speed.

The 16m wastewater pipe installation for Winslow in Geelong, Victoria, was expected to take up to two weeks using conventional methods. With the AdaptX trenchless drilling system, however, the job was completed in just four days – an outcome that has surprised even seasoned industry professionals.

Edge Underground Operations Manager Adrian Sneddon said the project showcased how the latest in trenchless technology can transform productivity.

“The AdaptX is an amazing machine to run,” he said. It’s not just the power of it that makes a difference, but the in-built troubleshooting features that mean unexpected issues are dealt with before they even have the chance to become problems.

The project involved installing DN1050 reinforced concrete jacking pipe (RCJP) with an outside diameter of 1194mm through clay containing rock floaters.

As with all AdaptX microtunnelling projects, a 350mm pilot bore was completed first, followed by a single back ream to expand the bore to a final size of 1220mm.

“That’s an impressive size-up by any standard,” Sneddon said. “Being able to go from a 350mm pilot to a 1220mm bore in one step is not something many systems are capable of achieving.”

The AdaptX system’s ability to switch between standard and geared back reaming

using a four-to-one reduction gearbox provides significantly more torque while slowing cutter speed, reducing wear and improving effectiveness in mixed ground conditions and hard rock.

Coupled with AdaptX’s vacuum extraction system, which improves ground stability and keeps the whole process neat and clean, this gives AdaptX its speed and capabilities.

AdaptX inventor and Edge Underground founder Stuart Harrison said the machine’s performance has repeatedly challenged expectations.

“Contractors are often concerned about whether microtunnelling jobs will finish on time. With AdaptX, we’re not just meeting schedules, we’re smashing them,” Harrison said.

“People find it confronting to see how quickly we complete these jobs. We might begin with a plan to run an older AXIS machine enhanced with AdaptX equipment, which is already more capable than the original. But once the full AdaptX system arrives on site, it often completes the job in the time it would take to set up other systems.”

The system’s capabilities don’t stop at mechanical performance. The AdaptX includes advanced monitoring and feedback systems that allow operators to identify and resolve emerging issues in real time.

By addressing potential complications before they become critical, the machine offers speed and reliability; two qualities not often found together in complex trenchless installations.

This blend of power, control and adaptability is part of a broader movement by Edge

Underground’s parent company, OptionX Group, to modernise and simplify the drilling, tunnelling and boring industry.

The company has been at the forefront of trenchless innovation in Australia and around the world.

Harrison, who is also the CEO of OptionX Group, has recently been on a mission to take advances in microtunnelling to the world, having recently met with companies in the Middle East looking to run AdaptX machines, and taught about vacuum extraction at the Microtunnelling Short Course in the US.

The Geelong project demonstrates how quickly the AdaptX is rewriting expectations. Harrison believes the industry needs to evolve – and fast.

“It’s clear that our industry is facing increasing demand for faster, more efficient solutions that don’t compromise on accuracy or safety,” he said. “AdaptX was created to meet those demands head-on.

“We know how valuable time is to our clients. Getting in and out quickly, with less disruption and lower overall costs, is the future of microtunnelling – and AdaptX is leading the way.”

With results like those seen in Geelong, AdaptX continues to gain attention in Australia and all over the world.

As more contractors look for efficient solutions that can handle complex ground conditions, the speed, power and precision of the AdaptX system are proving hard to ignore.

Trenchless trailblazing

Pezzimenti Trenchless has the civil infrastructure market covered, whatever the ground conditions.

Pezzimenti Trenchless has been shaping Victoria and South Australia’s subterranean landscape since its foundation in 1957.

Over the decades, the company has emerged as a trusted leader in trenchless pipeline construction, partnering with major infrastructure groups and becoming a go-to specialist for projects spanning sewer, water, drainage, gas and telecommunications.

At the core of Pezzimenti’s operations lies its laser guided microtunnelling system, which is backed by a fleet of vacuum trucks. Designed and built in-house, this microtunnelling technology enables the installation of pipes ranging from 325–1850mm in diameter through diverse ground types, and up to 1250mm in rock conditions.

“We pride ourselves on our unparalleled experience and expertise, as well as on our dedicated research and development program,” Pezzimenti Director Joe Pezzimenti told Trenchless Australasia

The company is currently undertaking a suite of projects that showcase its broad capabilities.

At the Love branch sewer in Wollert, Victoria, more than 1850m of 718mm glass-

reinforced polyester (GRP) jacking pipe is being installed through basalt, highlighting Pezzimenti’s ability to navigate hard rock conditions. In the Melbourne suburb of Blackburn North, the Eley Road branch sewer is progressing with 950m of 616mm, 516mm and 427mm GRP jacking pipe driven through siltstone.

Completed works demonstrate Pezzimenti’s breadth of expertise just as clearly. The company recently delivered sewer works for the Arts Centre in Melbourne, where the team faced challenging Coode Island silt conditions.

This type of silt is known for being unstable, prone to swelling, and not self-supporting, which can complicate traditional excavation techniques. But Pezzementi delivered the project with minimal disruption, installing 700m of 427mm and 324mm GRP jacking pipe.

Similarly, the company recently installed 1000m of 376mm GRP pipe through clay and sandy clay strata at Ridgelea Estate in Pakenham in Melbourne’s south-east.

These examples reflect the company’s ability to adapt to softer, environmentally sensitive ground conditions.

Whether free boring, sleeve boring or pipe jacking, the company ensures seamless

trenchless installation, tailoring its methods to each project’s technical requirements.

“Focused on delivering the best results for our clients, we are committed to providing the most efficient and effective solutions for every project, however big or small,” Pezzimenti said.

“Pezzimenti will continue to position itself at the forefront of the trenchless industry.”

In every sense, Pezzimenti stands as a partner on which the civil infrastructure industry can rely. Its in-house engineering capabilities, combined with the depth of its field experience and steadfast commitment to innovation, positions it well to continue delivering safe, reliable and cost efficient trenchless solutions across Victoria and South Australia.

Pezzimenti will be on the ground at this year’s No-Dig Down Under, to be held in Melbourne from 17–18 September. The event is the perfect opportunity for utilities, asset owners, and other stakeholders in the civil infrastructure sector to speak with the Pezzimenti team and learn how it can help elevate projects.

Underground intelligence, above-ground confidence

Untethered and in-service, the FLOAT AI is helping utilities and contractors rethink how high-risk sewer assets are inspected, prioritised, and managed at scale.

Foften the ones they can’t see. And when it comes to wastewater networks, some of which are more than 100m underground and several decades old, those risks can be hard to assess and even harder to address without introducing new ones.

Until now. Automaton Infrastructure’s FLOAT AI system is changing the game for trunk main assessment.

“FLOAT AI is the first and only untethered, AI-powered inspection platform in Australia designed specifically for largediameter wastewater pipelines,” Automaton Infrastructure Lead – Specialist Projects Sam Blanch told Trenchless Australasia

“It offers live condition insight over long distances, without needing to put people in the pipe.”

Built to operate in high-flow, high-risk environments, the FLOAT is able to travel up to 20km in a single run through live wastewater networks. No shutdowns. No dewatering. No excavation. And, critically, it minimises the need for confined-space entry.

The device carries a suite of non-destructive sensors, including high-resolution visual cameras, sonar, and ultrasonic thickness gauging, to build a detailed picture of what’s happening underground. This data is then run through FLOAT AI’s triage model, which categorises assets as ‘now, soon or later’, giving engineers and asset managers a defensible way to prioritise action.

or traditional assessments,” Blanch said.

“But we are trying to help teams do them more strategically. The FLOAT gives you a riskbased framework to work from. It’s about getting eyes in the pipe before boots hit the ground.”

That clarity is already being put to good use.

So far, FLOAT AI has been deployed across more than 250km of Sydney Water’s highest-risk assets, including the Northern Suburbs Ocean Outfall Sewer (NSOOS), a major transport sewer that carries roughly 25 per cent of Sydney’s total wastewater flow. In one deployment, The FLOAT completed a 14.2km untethered survey in a single run through live flow, delivering continuous 360°

visual and volumetric sonar data.

The result was high-resolution insights into sediment build-up, structural integrity, and flow capacity, captured in a single shift, without any of the traditional access risks. These outputs enabled a focused rehabilitation scope, avoided unnecessary planning work, and supported engineering decisions in areas too deep for safe entry or excavation.

That dataset now serves as a baseline for ongoing monitoring and future inspections, enabling Sydney Water to benchmark change, spot emerging faults early, and stretch asset life through proactive intervention.

But perhaps more importantly, FLOAT AI has become a cornerstone in the utility’s broader capital planning process. Its outputs are now embedded in the scope design of a new 100km/year structured inspection contract, signalling a shift toward data-led decision making at a network level.

“This is the kind of intelligence that builds over time,” Blanch said. “The more kilometres you inspect, the better your model gets. That means lower costs per run, more precise outputs, and greater confidence in the actions you take next.”

The FLOAT continues to support condition assessment programs across a growing number of trunk main networks.

As the pressure to do more with less increases, data-driven approaches like this are helping reshape how asset inspections are planned, prioritised, and executed, while reducing risk to workers and the network itself.

Independent testing confirms Denso Bore-Wrap’s HDD performance

As trenchless technology continues to evolve, so too does the expectation for protective coatings that can withstand the extreme demands of horizontal directional drilling (HDD).

The team at Denso Australia believe that these expectations must be met with evidence, not assumptions.

Since launching Bore-Wrap, Denso Australia has committed itself to an extensive program of internal research and development and independent third-party testing.

Its most recent collaboration with the National Facility for Pipeline Coating Assessment (NFPCA) at Deakin University provided valuable, unbiased insights into the product’s performance across a range of fieldrelevant conditions.

The testing assessed gouge resistance and adhesion strength using international standards including CSA Z245.20, NACE TM0215, and ASTM D4541. Two separate gouge test setups were used to reflect real-world HDD risks.

In both scenarios, Bore-Wrap demonstrated exceptional resilience.

In the weld margin configuration, it resisted gouging forces up to 1250kgF before disbondment – more than double the load required to compromise other tested systems. This is a critical result, as field joint weld zones are particularly susceptible to mechanical damage during pull-through.

Beyond its mechanical performance, BoreWrap also offers several practical and long-term advantages for trenchless pipeline installations. It is fully non-shielding, ensuring compatibility with cathodic protection systems.

The wrap is supplied in convenient, easy-

to-apply packaging and can be installed in multiple layers if required. Its field-friendly formulation allows for application in a wide range of environmental conditions, whether on-site or off-site.

Bore-Wrap’s patented fibre architecture ensures that during HDD installations, its flexural strength is greater than that of the underlying parent coating system such as FBE, 3LPE and 3LPE parent coatings.

This is due to its high fibre content which provides enhanced durability under HDD stress, unlike more brittle UV-cured ARO systems.

Adding to this, Bore-wrap’s overlaps are

smooth thus allowing for an easier installation uninhibited by larger overlaps which can cause additional stress on coatings and equipment.

From lab validation to in-field success (such as with recent applications in Bolivar, South Australia), Denso’s approach has been consistent and clear: test, refine, verify, and protect.

Denso Australia is committed to transparency, quality, and innovation. It invites engineers, asset owners, and pipeline professionals to explore the data for themselves.

Nordiloc: Made in Australia

Norditube, a global leader in trenchless pipe rehabilitation, is making its mark down under.

As a household name in pipe rehabilitation technologies, NordiTube operates across the US, Europe, Singapore, Australia and China, and has always aimed to provide partners with the best technical solutions.

The company made it a priority to grow its presence in the Australian market, best demonstrated by its acquisition of Aussie Trenchless in August 2024.

For over a decade, Sydney-based Aussie Trenchless had supplied SRP Expanda equipment and SRP PVC profiles to customers across Australia, New Zealand, Taiwan, South America and beyond.

Now, NordiTube Australia will take on the important job of delivering this Spiral Wound SRP Expanda business to its new and expanded customer base.

NordiTube Asia Pacific Managing Director Edmund Luksch said the SRP solution will now be promoted internationally under a new brand: Nordiloc.

“The Nordiloc technology for Gravity Pipes is an important addition to NordiTube’s portfolio, complementing our 40-year foundation in pressure pipe rehabilitation, including CIPP and IH liner technologies,” he said.

The first two SRP systems under the Nordiloc brand are Nordiloc X – a close-fit liner solution for diameters DN150–1200, and Nordiloc S – a steel-reinforced system for diameters DN600–3000.

In addition to the Adelaide-based sales centre, the newly established Sydney based unit of NordiTube will manufacture Nordiloc equipment with support from KRE Engineering.

From there, locally made Nordiloc

systems will be exported worldwide, marking an expansion of the former Aussie Trenchless business.

The first 10 Nordiloc units are set to be shipped from Sydney in 2025, with plans to double annual production to 20 units in the near future.

As climate change creates unpredictable conditions on job sites, installers are seeking technologies that minimise dependency on factors like resin curing under rainy conditions.

The Nordiloc system is not reliant on resin; it allows for controlled live-flow installations, reducing project risk and simplifying site logistics.

With production plants across the US, Europe, and the Asia Pacific region, NordiTube also offers customers faster lead times and greater material availability.

“It’s great to know that equipment manufactured in Australia will soon play a key role in rehabilitation projects around the world,” Luksch said.

In addition to exhibiting at No-Dig Down Under, Norditube’s presence at the event will extend to the conference room.

On Wednesday 17 September from 4.30pm–5pm, Norditube Central and Eastern Europe Sales Manager Thomas Samanns will deliver a must-listen presentation on CIPP- lining technologies for the trenchless rehabilitation of Asbestos Cement (AC) pipes.

The presentation will delve into the urgent global need to rehabilitate aging AC pipelines, which suffer from delamination at the joints, posing a risk of water contamination.

As traditional excavation and disposal are both hazardous and costly, the focus is on a smart, trenchless solution that preserves the integrity of the existing network.

A structural pipe-in-pipe system was developed to withstand internal and external loads for the next 50+ years, with the NORDIFLOW system emerging as the optimal technology.

It ensures minimal fibre disturbance and uses negative pressure with specialised filtration to safely manage any loose asbestos during pipe cutting.

Spacers prove vital in motorway extension

A important project in New South Wales made excellent use of kwik-ZIP’s HDXT-153 spacers.

kwik-ZIP’s HDXT, HDX, and HD Series spacers have been successfully appraised by the Water Services Association of Australia.

Vaughn Civil recently deployed the iconic HDXT-153 spacers from kwikZIP to facilitate the slip-lining of two water main runs as part of the M1 Pacific Motorway extension project.

kwik-ZIP’s HDXT-153 spacers were used to centre and support the carrier pipe inside the host pipe during the slip lining process.

The HDXT’s unique load-sharing design maximises the load-bearing capacity of each runner and reduces point loading. The simple and efficient installation process does not require any special tools.

The M1 Pacific Motorway extension is a $2.1 billion project funded by the Federal and New South Wales Governments that, once complete, will feature a 15km extension of the Sydney–Newcastle motorway, along with the removal of five sets of traffic lights.

All up, the project will result in a reduction of nine minutes of travel time during peak periods.

It will also deliver a 2.6km viaduct over the Hunter River and floodplain, the Main North Rail Line, and the New England Highway.

In addition, there will be new bridge crossings over local waterways at Tarro and Raymond Terrace, and an overpass for Masonite Road at Heatherbrae, improving connection between the M1 Pacific Motorway and the Pacific Highway and the surrounding road network, and leading to improved safety for all road users.

Vaughn Civil worked on runs of 62m and 127m and involving 1219mm OD Sintakote® Steel MSCL carrier pipes into 1574mm ID GRP casing.

kwik-ZIP’s HDXT-153 spacers were used to centre and support the carrier pipe inside the host pipe during the slip lining process.

The fusion-bonded coating on Sintakote pipes is crucial for corrosion prevention and must stay undamaged to work effectively. kwik-ZIP spacers not only provide protection but also feature integrated rubber grip pads, preventing slippage and preserving the coating.

kwik-ZIP spacers have no metal parts and are made from the company’s engineered thermoplastic blend that is flexible and extremely tough, and has a low co-efficient of friction.

In its commitment to going above and beyond, and despite all of kwik-ZIP’s products being equipped with comprehensive instructions, Business Development Manager Paul Keegan attended the site prior to the first installation to provide installation training and ensure a trouble-free utilisation of the product.

kwik-ZIP’s HDXT, HDX, and HD Series spacers have been successfully appraised by the Water Services Association of Australia (WSAA), with the products the only casing spacers on the market that have been approved as compliant by WSAA.

The WSA PS-324 product specification prescribes casings spacer requirements for correct protection of carrier pipes when installed inside casings.

Safety at the front of the line

Primus Line holds safety as its top priority approaching this year’s No-Dig Down Under.

German engineer Heiko Manzke has led Primus Line’s operations in Australia and New Zealand since 2019.

After years working at the company’s headquarters in Germany, he relocated to the east coast of Australia to support and grow the network built by his predecessor.

His role has been instrumental in expanding the company’s footprint in the region, bringing technical expertise to a wide range of projects.

Among the standout initiatives delivered under Manzke’s guidance are the rehabilitation of a vertical pipe, a series of wastewater pressure pipe renewals, and the first three-in-one project of its kind in Australia with Hunter Water.

Projects have also been completed in New Zealand and with major mining operator Rio Tinto. These efforts have helped solidify Primus Line’s reputation as a trusted and flexible trenchless solution for complex rehabilitation challenges.

A significant milestone came in 2020 when Primus Line entered a partnership with Interflow, one of Australia’s leading pipeline infrastructure contractors.

Interflow began stocking Primus Line products locally, ensuring faster delivery for urgent works.

While the exclusive agreement came to an end in mid-2024, the relationship continues, with Interflow remaining a key installation partner.

Primus Line will now also work with other regional specialists across the water sector to further expand its reach.

The company is also seeing early success with its overland piping system, a temporary, above-ground pipeline primarily aimed at mining applications. According to Manzke, the potential in the region is clear.

“Australia and New Zealand are extremely interesting markets for a pioneering product like ours,” he said. “The local network operators and engineering firms are highly qualified and therefore greatly appreciate a high-quality product made in Germany.”

He describes Primus Line as offering more than just a technical solution. “We provide a carefree all-in-one package – a first-class

This year, Manzke will present a technical paper on a topic of growing relevance: the relining of asbestos cement (AC) pressure pipelines.

“In my paper, I am presenting on the advantages of relining asbestos cement pressure pipelines using the Primus Line system,” he said. “I will demonstrate how this

approach eliminates the need for pipe removal, minimises hazardous fibre release, and complies with stringent occupational safety regulations, particularly those defined in TRGS 519.”

Recognised by Germany’s DGUV (German Social Accident Insurance) as a low-emission procedure, the Primus Line method provides a legal and low-risk pathway for AC pipeline rehabilitation.

“Through realised projects, I’ll highlight the benefits and practical advantages for operators,” Manzke said. “This trenchless solution offers a sustainable and efficient alternative to traditional methods and represents a significant advancement in asbestos pipeline rehabilitation.”

Safety, transparency and regulatory leadership are core to Primus Line’s identity, particularly in areas such as asbestos and PFAS.

“At Primus Line, we stand for transparency and innovation, always striving to lead in regulatory compliance,” he said. “We don’t just talk; we act. Every claim we make and every product we market is backed by independent testing.

“The safety, health and wellbeing of everyone involved in a Primus Line installation are of utmost importance to us. That’s why we continuously test our products – to guarantee this level of safety and quality.”

Double dose of innovation

No-Dig Down Under attendees will get a first look at two of the most talked-about additions to the Ditch Witch CEA fleet – the JT21 directional drill and the purpose-built AX30-300 vacuum excavator.

Making their debut appearance at a major industry show, the JT21 and the AX30-300 are engineered to deliver next-level performance across trenchless and utility installation projects, offering a double dose of cutting-edge technology for Australian operators.

A leap forward

The JT21 is the latest evolution in Ditch Witch’s horizontal directional drilling (HDD) line-up, building on the success of the JT20 while packing in a host of performance upgrades.

In a market where productivity and reliability are non-negotiable, the JT21 lifts the bar with up to 40 percent more downhole horsepower than its predecessor and, according to Ditch Witch CEA, a 35 per cent faster carriage speed than other drills in its class. It’s built for crews that need to move faster, drill smarter, and deliver consistent results in tight or complex work environments.

At the heart of the JT21 is a robust 74-horsepower (55kW) Deutz TD2.9 diesel engine, which is designed to produce consistent power across a wide range of ground conditions.

The drill’s 21,000 pounds (lbs) of pullback and 20,000lbs of thrust give it the strength to tackle tough utility installations, while 2250 foot-pounds of rotational torque allow for precise control and efficiency.

Beyond the numbers, the JT21 is defined by its thoughtful design. A lower centre of gravity improves stability and operator confidence, especially on uneven ground.

This subtle shift in engineering , Ditch Witch CEA Brand Leader Scott O’Hare said, makes a substantial difference in safety and performance, especially during pullback operations or when operating on sloped terrain. By placing heavier components closer to the ground, the machine is less prone to tipping, allowing operators to push harder without compromising control.

Technology also plays a pivotal role in the JT21’s edge. The integration of Virtually Assisted Makeup and Breakout (VAM) streamlines one of the most critical parts of HDD operations. Rather than relying on traditional floats and sensors, the VAM system uses electronic controls to ensure drill pipe is connected and disconnected at precisely the right torque. The result is greater consistency, reduced wear on threads, and a lower risk of damage that can slow a job down.

The JT21 delivers up to 40 per cent more downhole horsepower than its predecessor.

It’s an addition that helps protect equipment investments while maintaining productivity in the field.

The JT21 is also equipped with a highcapacity, low-RPM fluid pump capable of generating 132L per minute. Running at lower speeds extends the life of the pump and its wearable components, reducing service intervals and long-term operating costs.

In the operator’s seat, control and visibility have taken another leap forward.

The multimode joystick system allows for familiar control styles, including Ditch Witch, Competitive and American Augers control patterns, enabling seamless transitions between machines and making training more intuitive for mixed-experience crews.

Paired with integrated LCD screens that provide real-time diagnostics and performance data, the machine provides operators with more insight than ever into what’s happening below ground.

In a vacuum

If the JT21 represents a major leap forward in drilling performance, the Ditch Witch AX30-300 brings a similar level of innovation to vacuum excavation – a technique rapidly becoming the preferred method for exposing underground services.

Safer, cleaner and more precise than traditional excavation methods, vacuum excavation is gaining serious traction across infrastructure and utility projects.

The AX30-300 was developed specifically for the Australian market and brings together the power, capacity and ease of use that contractors

need in a trailer-mounted vacuum excavator.

The machine is equipped with a 32.5-horsepower Kubota diesel engine, offering reliable suction performance while maintaining fuel efficiency. With a 1135L spoil tank – the largest in its class on a 4.49-tonne GVM trailer – the AX30-300 is designed to minimise downtime and maximise time spent on the job.

Every aspect of the AX30-300 is engineered for efficiency and durability, from its hydraulic rear door and tank tilt system to its silenced power pack, which keeps noise levels low without compromising power.

Controls are positioned for kerbside access, while the hose reel system is designed to keep tooling always connected, allowing for faster mobilisation and set-up.

The machine also prioritises easy maintenance, with a high-capacity cyclonic filtration system significantly reducing the need to clean filters, keeping the machine running longer between service intervals.

Together, the JT21 and AX30-300 represent the next generation of productivity for Australian contractors. With power, precision and user-first engineering at their core, these machines reflect Ditch Witch CEA’s ongoing commitment to helping customers work faster, safer, and more profitably.

As always, Ditch Witch CEA backs its equipment with national support, training and service capabilities, with branches in Adelaide, Brisbane, Rockhampton, Mackay, Melbourne, Perth and Sydney.

On FMG’s Iron Bridge magnetite project, the company successfully delivered two simultaneous 499m river crossings of the Turner River, installing twin DN650 steel pipelines in hard rock exceeding 120 megapascal. ParaTrack magnetic guidance systems enabled accurate drill path control through variable geology, while real-time data analytics informed tooling adjustments mid-drill. With multiple rigs operating concurrently, the project achieved schedule efficiencies and mitigated program risk.

In the Kosciuszko National Park, Cape Dunstans was engaged to remediate and complete three critical utility crossings for Snowy 2.0 after previous contractors were

within a highly sensitive environmental zone. Cape Dunstans remodelled hydrofracture risks for each shot, implemented bespoke fluid recycling systems, and worked closely with environmental personnel to ensure full compliance. All three crossings were delivered without incident, reinforcing the company’s ability to complete technically and environmentally sensitive projects.

Off the coast of Queensland, Cape Dunstans was engaged by the University of Queensland to construct new seawater intakes at the Heron Island Research Station. This nationally significant project was the first use of HDD beneath a live coral reef within the Great Barrier Reef Marine Park. Under strict regulatory controls, the project team used biodegradable drilling fluids, gyroscopic steering technology, and noise reduction curtains to minimise impact to the environment. A conductor casing was installed to safeguard a freshwater lens beneath the island’s surface that supports rare terrestrial vegetation. The completed intake system exceeded expectations and delivered a critical upgrade for the research

engineering design, environmental planning, and HDD expertise to deliver safe, efficient, and innovative outcomes. The company’s in-house fluid recycling systems reduce waste, support compliance, and enhance performance in constrained and high-risk environments –proving critical in projects like Snowy 2.0, Iron Bridge, and Heron Island.

As demand grows for lower-impact, high-performance infrastructure, trenchless technology will continue to play a key role. Cape Dunstans is ready to meet that demand, offering intelligent, field-proven solutions delivered with professionalism and care.

Built-in reliability

Project profitability hinges on dependable equipment – and Vacuum Truck Supplies delivers the reliability that drives results.

From communities and councils to asset owners, civil infrastructure projects involve many stakeholders, but it only takes one equipment failure to derail progress and inflate costs. That’s why reliability isn’t just valuable – it’s profitable.

To that end, Vacuum Truck Supplies (VTS) is turning industry heads with its bold offering: a five year structural warranty for its vacuum trucks, paired with round the clock support.

“Our five-year warranty is industry-leading,” VTS Managing Director Rod Glue told Trenchless Australasia

“It goes to show how confident we are in our products, as well as the calibre of feedback we’ve been getting from our customers for years.”

Indeed, VTS has been a long-time supporter of the Australian trenchless industry, boasting more than 30 years of experience and over 1000 vacuum trucks built to date.

The latest additions to its fleet, the DiggerVac and DrainVac, are delivering reliable non-destructive digging (NDD) and draincleaning services to projects across Australia.

Both models come in a highly manoeuvrable 6x4 configuration – ideal for tight urban environments – while the heavy-duty 8x4 option is built for larger jobs and heavier payloads.

With high payload capacity, powerful pump technology and durable stainless-steel construction, each of the new models means serious business.

These robust machines combine tested durability with a straight forward, non computer control system – ideal for operators who demand performance without the burden of over-complexity. Relying on simplified drive line and control components, which have been proven for decades, means intuitive operation, greater reliability and simple maintenance.

“VTS has designed its own non-computer control system for hassle-free operation and maintenance,” Glue said. “Our trucks have been designed to withstand the harshest Australian conditions and are built to be abused.”

These combined features have been a huge hit with customers.

Geelong-based D.A. Beretta Plumbing and Gasfitting has been using VTS vacuum trucks since 2009, and picked up the new DrainVac shortly after it launched in 2024. Company owner Chris Beretta said the truck has been performing especially well amid heavy use.

“We use the truck virtually every day for hydro excavation as part of a water services replacement project for a large water utility,” he said.

“We’re working around services that we need to identify in the ground. We use this machine to eliminate the risk of damaging these services, which can easily happen through mechanical excavation.

“The system is easy to operate, is efficient and digs very well.

“If we need back-up or parts support, VTS is more than happy to help. Their ethos is that they offer exceptional support for their products and customers.”

Attendees to No-Dig Down Under 2025 will get the chance to see this new range up close and personal.

“We’re excited to showcase our new range of vacuum trucks at the event,” Glue said. “If you want to see them in person and learn more, come to the show and pay us a visit.”

In a market where underground work is increasingly congested and non destructive digging is essential, having machinery that performs reliably day-in, day-out is non negotiable.

VTS takes the guesswork out of the equation, delivering vacuum trucks that are easy to operate, and backed by reliable support that protects a project’s bottom line.

Channeline rehabilitates 5.3m diameter sewer

Channeline’s innovative multi-segmental GRP lining technology provided a robust solution for complex large-diameter sewer rehabilitation in the US.

Wunderground infrastructure, Channeline continues to raise the bar with its bespoke, fully-structural glass-reinforced plastic (GRP) liners. A project in Detroit, Michigan, highlighted Channeline’s capacity to deliver custom-designed, large-diameter, and multi-segmental liners that meet the unique challenges of trenchless rehabilitation on a monumental scale.

In 2021, Channeline supplied GRP liners for a pilot rehabilitation project on the North Interceptor – East Arm (NI-EA) in OaklandMacomb County, Detroit. The section of sewer in question, constructed in the 1970s, measured an enormous 17.5ft (5.3m) in diameter and had suffered significant structural deterioration due to corrosion from high hydrogen sulphide levels.

To meet the challenge, Channeline delivered a custom four-piece multi-segmental liner with a 16ft (4.9m) internal diameter and a wall thickness of 3.54 inches (9cm), designed to withstand severe loading using AWWA M45 Direct Bury methodology. The solution was also tailored to accommodate a six-degree curve in the alignment; a true demonstration of Channeline’s design flexibility.

Large-diameter pipes come with equally large logistical hurdles, particularly shipping.

scale. This drastically reduced freight costs and simplified delivery for a liner system that was otherwise too large for conventional transport.

“Onsite, the multi-segmented units were quickly and securely bonded using Channeline’s proprietary structural adhesive, achieving the same integrity and 150-year service life as their monolithic counterparts,” Channeline Chief Operational Officer Tim Webb told Trenchless Australasia

One of the key breakthroughs made possible by Channeline’s tongue-and-groove design is the ability to install structural liners through existing manholes or access shafts, entirely trenchlessly. This was critical in Detroit, where the construction footprint had to be kept under 150ft (45.7m).

Contractor Marra Services worked closely with Channeline’s design team to fine-tune the liner for ease of handling and placement, including solving the project’s most complex challenge: a tapered curve transition midline.

As well as the customisable qualities of Channeline GRP, the material also offers excellent durability thanks to its resistance to extreme temperatures, ultraviolet radiation, and chemical exposure.

On the Detroit project, a spray-in-place liner installed in 2017 had already shown signs of deterioration under harsh chemical conditions by 2021. This prompted a full replacement of an additional 110ft (33.5m) using Channeline.

“As far as we are aware, this is the largest fibreglass sewer liner ever built to date. This was a huge challenge for Channeline, but I was confident in my team and the Channeline product to get this done and exceed expectations,” Webb said.

Thanks to Channeline’s custom design and manufacture processes, large-diameters, non-circular profiles and complex curves are no problem for these liners.

Certainty you can build on

Every underground service located before excavation begins tells part of the story.

But without a digital record, it’s a story that can easily be lost.

Asset location maps provided by utilities are a helpful starting point, but they are indicative only, not a guarantee of exact pipe or cable position. That’s why savvy planners, project managers, and contractors are asking their utility locating and hydro excavation teams to map and record utility positions using highprecision GNSS equipment and the Geolantis 360 platform.

Geolantis 360 is a utility mapping software that transforms a standard mobile device into a powerful tool for capturing, recording, and visualising essential utility and infrastructure data.

It offers unmatched speed and precision in mapping buried utilities such as cables, pipes, ducts, and drainage routes, all enriched with comprehensive metadata on type, depth, and cover.

Geolantis 360 creates accurate, geospatially referenced maps that can be exported into GIS, CAD, or Google Earth formats, giving contractors a reliable, shareable record throughout the job. This supports better planning, more innovative work sequencing, faster site briefings, and improved health and safety outcomes.

Unlike standard smartphone GPS, which can be inaccurate by several metres, GNSS survey-grade equipment used with Geolantis 360 delivers centimetre-level accuracy. That level of trust in the data makes a significant

The rapid evolution of underground locating means all you need might already be in your pocket.

difference when planning work near critical infrastructure.

More importantly, digital locates provide certainty, not just in asset positions, but also in the cost of protection, strike avoidance, and minimising unnecessary utility cable.

In addition, Geolantis 360 is pre-configured to comply with the AS5488 standard – an Australian standard for the classification and management of subsurface utility information.

In a recent project, subsurface utility detection specialists Subsurface Mapping Solutions utilised the Geolantis 360 technology to work through a challenging project.

Subsurface Mapping Solutions Director Andrew Watson said the company was impressed by the technology.

“The overall user experience with Geolantis 360 has been very positive for our team,” he said. “The platform has proven to be intuitive and user-friendly, which has made the transition smoother and more effective.”

Unlike standard smartphone GPS, which can be inaccurate by several metres, GNSS survey-grade equipment used with Geolantis 360 delivers centimetrelevel accuracy.

The technology replaced multiple fragmented tools with a single, integrated platform that allowed for a more seamless management of mapping projects from start to finish.

PelicanCorp is a niche provider of software and services to utilities, asset owners and to the one call industry specifically for the protection of essential infrastructure.

PelicanCorp’s unique technology platforms are developed through deep global industry knowledge and market experience.

The company uses its own platform of products to deliver services such as beforeUdig New Zealand, BHUG, Promark, and LocateServices NZ.

Built for Australia’s toughest jobs

Vacvator’s latest and most advanced vacuum excavation unit, the HD 8-90 NDD, will make its debut at No-Dig Down Under 2025.

The curtain is about to be lifted on Vacvator’s HD8-90 non-destructive digging (NDD) truck, a powerful 5000cfm, 9000L vacuum truck engineered to deliver exceptional payload capacity and performance – all while staying compliant with Australian transport regulations.

This model stands out for its ability to legally carry up to nine tonnes of payload on Australian roads, an achievement made possible by meticulous engineering and a deep understanding of national standards.

Vacvator General Manager Con Alvanos said the unit was born directly from industry feedback.

“The market has been calling for a highperforming hydro excavation unit that can legally carry serious payload without compromising on power or usability,” he told Trenchless Australasia.

“That’s exactly what the HD 8-90 NDD delivers.”

A product of painstaking design, the HD 8-90 NDD is built to carry maximum spoil tank loads keeping in mind axle loading limitations, making it ideal for contractors and

asset owners who demand compliance without sacrificing productivity.

Safety and compliance are at the core of the truck’s design. A standout feature is Vacvator’s intelligent CAN bus operating system that automatically disables the blower once legal load limits are reached.

“The CAN bus system protects the operator, the business owner and other road users,” Alvanos said.

Paired with the robust Iveco S-Way truck into which the unit is incorporated, the HD 8-90 NDD is a heavy-duty machine that knows its limits.

The model also boasts outstanding performance. Each unit is fitted with a powerful 5000cfm (8495m3/h) blower capable of generating up to 28”Hg (95kPa) vacuum. This is further supported by two NDD highpressure water lances which can deliver 32L per minute at 3600psi (248bar).

Put simply, the HD 8-90 NDD is built for bulk haulage to make light work of even the toughest excavation tasks.

“With a top-of-the-line excavation system, 9000L of spoil and 4000L of water, this unit

offers the power, suction and capacity needed for the most demanding applications,” Alvanos said.

And just like all Vacvator trucks, the HD 8-90 NDD is built to the same standard of care that the trenchless industry has come to expect.

“Our trucks are easy and safe to use, with intuitive controls and operator-focused designs,” Alvanos said. “But our commitment to our machines and our customers extends well beyond the moment the trucks roll out of our shop.

“We provide operator training and fullservice support. Smart features built into our machines also allow us to perform remote diagnostics, minimising downtime and maximise return on investment.”

With the backing of a three-year warranty on all Vacvator-made components, local manufacturing and a reputation for service and support, the HD 8-90 NDD is a true nextgeneration solution for vacuum excavation.

“We look forward to showcasing this new unit and connecting with the trenchless community at No-Dig Down Under in September,” Alvanos said.

On a roll in New Zealand

Smart Lock Group continues to deepen its presence across the Tasman, reinforcing its position as a go-to provider for efficient, trenchless repair solutions.

Contractors NuFlow and Pipework

Solutions – both owned by Dan Barnett – recently rolled out the Smart Lock repair system on their New Zealand trenchless projects, with the first being deployed in rehabilitation works for a major water utility on the North Island.

Backed by training and installation support from Smart Lock Group, the contractors executed the project efficiently and with no issues.

“The team has done an awesome job,” an asset manager from the utility company said. “The Smart Locks looked nice and tidy. We thank them for their good service.”

This is the latest in a long list of glowing reviews for Australian-based Smart Lock Group. The company’s flagship Smart Lock is also a domestic success, ensuring the structural repair of cracks, breaks, and voids in pipes.

With a simple load, lock and leave design and no curing time, Smart Lock is made for rapid deployment without the disruption potentially associated with traditional repair methods. The system consists of a stainless-steel sleeve and locking system, fibreglass matting, and silicate resin that adheres to moist surfaces and has a high resistance to acid and alkaline water.

A Smart Lock sleeve can be installed in as little as 30 minutes, which the company said not only cuts down operational costs but also helps to minimise a project’s carbon footprint.

Installing the Smart Lock system is straightforward and installation equipment includes a wheeled packer, CCTV inspection camera, air compressor, pull line, layout table, personal protective equipment, and additional

safety equipment including underground access equipment.

The solution is suitable for pipes ranging between 100–900mm in diameter, with a larger variation called the Big Bore suitable for 1050–2100mm applications.

But Smart Lock Group delivers more than just a product. Team members like National Technical Manager Michael Nickolaus work closely with contractors such as NuFlow and Pipework Solutions to ensure systems are correctly deployed and will stand the test of time.

“Michael from Smart Lock is a great communicator, passionate about the product and a great all-round guy,” NuFlow Operations and Installation Technician Greg Young told Trenchless Australasia. “He was willing to teach us about the product and assist us with our first installations, which was a great confidencebooster for our team.

“Smart Lock is a simple, well-designed, fast-to-install product that has a robust stainless finish that looks great and fits perfectly.

“We look forward to using many more Smart Locks.”

For Nickolaus, the respect was mutual.

“NuFLow and Pipework Solutions are terrific partners, always striving to provide the best avenue of works for their clients using outside the box thinking,” he said.

“Dan Barnett is able to draw from his range of businesses across the trenchless, plumbing and heating sectors to find a solution to most challenges facing the market.

“Smart Lock Group looks forward to deepening its relationship with Dan and his team throughout New Zealand.”

Facing the future

Ready Group is building a greener world through its environmental stewardship initiatives.

Ready Group has earned a name in the trenchless industry for its vacuum excavation, liquid waste management, jetting and drain-cleaning services, but there’s much more to this company than meets the eye.

Behind its broad suite of civil construction services, Ready Group is a company with environmental stewardship carved into its bedrock.

Central to this effort is Ready Group’s adoption of an environmental management system certified to ISO 14001 standards. This framework is recognised globally for its structured methodology in identifying, managing and enhancing environmental performance through continual improvement, legal compliance, resource efficiency and waste reduction.

Holding this certification since 2017 reflects Ready Group’s proactive stance on environmental risk, positioning it ahead in regulatory compliance and bolstering its reputation among stakeholders.

In recent years, a more ambitious approach to carbon accountability has taken shape.

Ready Group began offsetting 100 per cent of its Scope 1 emissions in 2021, broadening

this commitment in 2024 to include Scope 2 emissions through a formal partnership with Greenfleet. That alliance resulted in the offset of approximately 903 tonnes of CO₂ in the 2024 financial year, achieved via reforestation projects that restore biodiverse ecosystems and absorb carbon from the atmosphere.

Greenfleet CEO Wayne Wescott commended Ready Group for working towards genuine climate action.

“By working with us to remove their emissions, Ready Group is enabling the restoration of protected native forests,” he said.

“Since partnering with us in 2024, the company has directly contributed to reforestation projects in Queensland and Victoria which are delivering climate action and protecting our environment.

“It is thanks to organisations like Ready Group that Greenfleet can protect our climate and restore nature in this way. We’re proud to partner with them to grow climate hope.”

Ready Group’s environmental ethos extends far beyond carbon offsetting. All Ready Group plant and equipment runs exclusively on biodiesel, significantly reducing reliance on fossil fuels and curbing emissions.

The company also practices circular construction waste management, ensuring materials are reclaimed and recycled through a licensed waste partner network, which diverts substantial volumes from landfill.

In administrative settings, waste is meticulously sorted and recycled. Employees participate in beverage-container-return programs with proceeds donated to charity, and purchasing policies favour eco-friendly consumables such as recycled paper, compostable bin liners and sustainable cleaning products.

These collective actions underscore the company’s philosophy that incremental choices contribute to meaningful environmental change.

Further cementing its hands-on approach, Ready Group team members joined Greenfleet’s tree-planting day in August at the Lucas Heights Conservation Area, directly taking part in ecosystem restoration and biodiversity enhancement firsthand.

Together, these efforts paint a picture of a company deeply invested in environmental stewardship. For more information, visit readygroup.au

The ISTT’s International No-Dig is Landing in Auckland in 2026

New Zealand International Convention Centre, Auckland 28 – 29 October 2026

International No-Dig provides an unparalleled opportunity to connect with the global trenchless technology industry. Hosted each year in a different country to showcase the global industry, International No-Dig will bring together the best of the innovations and advancements in trenchless technology.

Driving sustainability with smarter plastic pipe systems

Plastic pipes have transformed the way we live, delivering essential services to homes and communities.

As Australia sharpens its focus on lowering environmental impacts and shifting from a linear to a circular economy, plastic pipes are increasingly becoming the preferred choice for infrastructure renewal and upgrade projects.

Designed for durability and recyclability, plastic pipes align strongly with circular economy principles. They minimise waste and pollution, remain in use for decades, and are recyclable at end-of-life. These attributes are especially amplified when combined with trenchless installation methods, such as directional drilling, pipe cracking, slip lining, and swage lining, which significantly reduce disturbance to the environment and communities.

“One of the important features of plastic pipes is their design life,” PIPA Executive General Manager Cindy Bray said.

“They are intended and designed to last over 100 years under typical environmental conditions – remaining functional and lowmaintenance when installed correctly and used as intended.”

Plastic pipes are manufactured efficiently in clean production facilities with low emissions and low embodied energy.

Where suitable, recycled pre- and postconsumer materials can be incorporated in accordance with relevant standards, ensuring performance is maintained whether pipes are made from virgin or recycled materials.

In support of informed, evidence-based material selection, PIPA recently commissioned two independent Life Cycle Assessment (LCA)

studies through Edge Impact. These studies, aligned with ISO 14040/44 and underpinned by third-party verified Environmental Product Declarations (EPDs), compare the environmental performance of plastic pipe systems – including PE, PP, and PVC – with traditional materials such as ductile iron and steel-reinforced concrete.

Covering key infrastructure applications like water supply and drainage, the studies evaluated a wide range of environmental indicators: carbon footprint, water use, energy consumption, transport emissions, and recyclability.

“While no one material outperforms across all categories, the LCA results show that plastic pipes consistently deliver strong advantages – particularly in reducing greenhouse gas emissions, conserving water, and supporting circular economy outcomes through local manufacturing and recyclability,” Bray said.

These findings are particularly relevant as governments and infrastructure providers pursue climate-resilient, cost-effective and lower-impact solutions.

Plastic pipes paired with trenchless technology provide further environmental and financial benefits. Trenchless methods allow for installation without large-scale excavation, reducing disruption to ecosystems, waterways, roadways and urban environments.

“Plastic pipes used in buried infrastructure like water will likely never be dug up, even at the end of their long service life,” Bray said.

“They’ll become a host pipe for a new pipe, inserted using trenchless techniques, saving enormous energy and material

critical. PIPA’s Industry Technical Guideline POP003: Butt Fusion Jointing of PE Pipes and Fittings, reflects global best practices and offers guidance on equipment, operator competence, quality assurance, site records, and testing.

“This guideline also offers important insights for asset owners and project managers,” Bray said.

“By understanding the role of welder competency in long-term asset performance,

Leading Underground Asset Safety.

Plastic pipes combined with trenchless installation represent a smart, sustainable solution for Australia’s infrastructure future. With verified environmental performance, long design life, and the ability to support circularity, they provide a powerful pathway toward cost-effective, low-impact, and resilient pipeline networks.

“By using resources responsibly through better design, we’re working smarter,” Bray

Raising the bar

Australian Custom Pipes has ramped up its manufacturing capacity to better support the PE100 market.

For more than two decades, Australian Custom Pipes (ACP) has worked to establish itself as a trusted name in the manufacture of high-density polyethylene pipes (PE100), fittings and custom fabrications.

Known for its fast turnaround times and manufacturing flexibility, ACP produces PE piping in a wide array of specifications, including custom coils up to 500m in length, and with colour-coded striping for gas, water, fire hydrant, electrical conduit, and communication lines.

PE100 is a go-to pipe choice in many trenchless utilities’ projects owing to its inherent corrosion resistance, light weight, flexibility and ease of installation. As urban centres and infrastructure expand, demand for PE100 pipe has seen a sharp increase.

In response, ACP is raising the bar by ramping up its manufacturing capacity with additional production line machinery.

“ACP has increased its capacity to manufacture PE100 pipe in step with our customers’ growing demands,” ACP Managing Director Dennis Jones told Trenchless Australasia.

“This update to the business has all the bells and whistles to ensure we are still delivering the quality pipes that ACP is known for in the market, so that we can continue to meet customers and industry expectations.”

The newly commissioned production line is more than just an expansion, it’s a strategic investment in efficiency, flexibility, and quality. The increased capacity allows ACP to shorten lead times, manufacture specialised sizes and lengths, and reduce pressure on existing production lines.

“The new line is exactly what ACP needed to deliver for its customers,” ACP Production Manager Tim said.

“It’s taken the pressure off other lines which are highly utilised, and in turn has allowed us to employ more technicians to run the operation efficiently.”

In an era where domestic manufacturing faces mounting challenges, ACP’s continued investment in its people and technology is a standout achievement.

“It is great to see an Australian-owned company continuing to prosper in these challenging economic conditions,” Jones said.

“This can be put down to ACP’s great team, machinery and loyal customers.”

Built on quality, backed by training ACP’s strength lies not only in its machinery but in its people. Every technician and team

member undergoes rigorous training, with a company-wide training matrix ensuring

delivery of high-performance PE pipes. All of these pieces come together to make

Leveraging the company’s access to the ParaTrack™ HDD Guidance System paired with decades of field-proven expertise, Prime Horizontal’s team across Australasia supports contractors and operators with the specialised tools and technical know-how needed to tackle the region’s toughest crossings, from remote terrain to busy urban corridors. With a focus on professionalism, ethics, and client collaboration, Prime Horizontal is helping shape the future of trenchless technology throughout Australasia.

With more than 25 years of hands-on experience in the HDD industry, Gary Bowen serves as Operations Manager for Prime Horizontal’s Australasian operations, leading the company’s growing presence from its Brisbane base. Gary’s career began in the UK as an HDD mechanic and drill operator, steadily

building his expertise across every level of HDD fieldwork – from walkover systems and wireline steering to site supervision and project management. Since joining Prime Horizontal in 2013, he has become a trusted resource for Australasian contractors tackling some of the region’s most technically demanding trenchless projects.

Under Bowen’s leadership, the Brisbane office provides comprehensive guidance services using the ParaTrack HDD Guidance System, while also offering mud motors, rock reamers, and the increasingly in-demand GyroTrack service. He and his team support projects not only throughout Australia but also across Japan, Taiwan, Thailand, Indonesia, and beyond. Prime Horizontal offers clients design input, technical troubleshooting, and precision tools that help deliver safe, accurate bores, even in challenging urban corridors or remote offshore energy sites. Bowen’s decades of handson HDD experience allow him to bring an insider’s understanding of what contractors face in the field. Prime Horizontal offers more than just technology, it brings practical support and

guidance that gives clients confidence to tackle the toughest crossings.

According to Bowen, one of the strongest drivers for HDD work in the region right now is the growing demand from the electric sector, especially for offshore power projects. Much of Prime Horizontal’s recent activity in Taiwan and Japan has focused on offshore energy installations, and similar projects are emerging in Australia as well. Onshore, cities like Melbourne are seeing a surge in small rig HDD work where tight urban corridors and strict accuracy requirements mean traditional walkover systems are no longer enough. In these cases, the ParaTrack Gyro Module is proving essential, giving contractors the accuracy needed to navigate congested underground spaces and meet demanding tolerances that ensure new trenchless infrastructure is installed exactly where it’s designed to be.

Bowen said that the ParaTrack Gyro can be used with a compact 4–3/4-inch drilling assembly, making it versatile enough to run on smaller 15- or 18-tonne rigs. This flexibility

is especially valuable in urban environments where contractors often face surface access limitations. The ParaTrack Gyro allows them to achieve the required accuracy without the need for surface coils.

Case study: Snowy Hydro’s complex intersects

One standout example of Prime Horizontal’s expertise in action was its work on the iconic Snowy Hydro project in the remote mountains of New South Wales. In this supporting role, Bowen and his team provided guidance

services for three critical HDD intersects – each crossing stretching nearly 3000m in length with an elevation change of around 600m. Navigating this challenging terrain demanded not only precise steering and advanced technology but also the practical insight to manage extreme length and elevation shifts deep underground. Prime Horizontal’s contribution helped ensure these complex bores were completed safely and accurately, playing a vital role in one of Australia’s most ambitious renewable energy infrastructure expansions.

Looking ahead, Bowen remains optimistic about the outlook for HDD and trenchless work across Australasia. While the market has been temporarily impacted by tighter government budgets and shifting priorities, he sees clear signs of momentum building. Major infrastructure drivers like the upcoming Brisbane Olympics and the ongoing expansion of power, internet, and offshore wind networks promise a steady rise in drilling demand in Australia and neighbouring regions such as Taiwan. Backed by Prime Horizontal’s depth of expertise and field-proven technology, Bowen is confident his team is well positioned to support contractors as the region’s next wave of critical projects gets underway.

Manufacturing Quality PE100 Pipes

Delivering Customer Satisfaction with Quality Products and Service

Since 2004, Australian Custom Pipes (ACP) has been providing conventional piping systems, custom pipes, injection moulding and fabrication to the Gas, Water, Fire, Electrical and Communications pipeline construction industries

S&Z Australia’s contribution

In a significant step toward improving Melbourne’s road infrastructure, S&Z Australia has successfully contributed to the M80 Ring Road Completion as part of the North East Link Program – Victoria’s largest ever road project.

The company’s involvement centres on a strategically important section between the Greensborough Highway and the VicTrack rail corridor. Here, S&Z Australia was engaged to carry out precision micro-tunnelling operations

two separate bores, ensuring the installation of pipelines without disturbing the surrounding roadways, rail lines, or utilities. These bores included two lengths of 123m reinforced concrete jacking pipe – one DN600mm and the other DN400mm.

These pipelines are more than just conduits, they form protective sleeves, housing essential water infrastructure: a 450mm mild steel cement lined (MSCL) water main and a 300mm MSCL water main. By safely enclosing these mains

at the Grimshaw Street Interchange. As one of the more complex intersections in the northeast corridor, Grimshaw Street is set to undergo a full transformation, requiring pre-installed services to streamline the main works and avoid costly delays.

To complete these micro-tunnelling works, S&Z Australia employed a dry excavation method.

To complete these microtunnelling works, S&Z Australia employed a dry excavation method, a progressive approach that contrasts with traditional wet slurry tunnelling. This technique is centred on the use of the Bohrtec Microtunnelling Machine, which efficiently removes dry spoil via augers, eliminating the need for high volumes of water.

The underground pipeline works were a crucial

S&Z General Manager Jim Pound said the choice to use dry excavation is in line with the company’s commitment to environmentally conscious and cost-effective construction solutions.

“Unlike conventional tunnelling techniques that rely on vast amounts of water to create a removable wet slurry, the Bohrtec MicroTunnelling Machine efficiently extracts dry spoil through augers. This approach eliminates excessive water usage and significantly lowers the environmental footprint of tunnelling projects,” he said.

Pound added that dry excavation is particularly effective in urban environments like Greensborough, where managing water and slurry disposal presents additional logistical and environmental challenges.

PROJECTS

Key benefits

The use of dry excavation on this project delivered a range of benefits across waste management, logistics, environmental sustainability, and overall project efficiency. By removing dry spoil rather than slurry, the volume of waste was significantly reduced, making disposal both faster and simpler.

This approach also allowed for greater flexibility on-site, with dry material able to be stockpiled temporarily and removed by tip truck at more convenient times, easing congestion and supporting better sequencing throughout the construction program.

From an environmental standpoint, the elimination of slurry treatment not only conserved large amounts of water but also removed the need for complex disposal systems, aligning the project with modern sustainability standards.

Operationally, the simplified spoil management process helped streamline the tunnelling workflow, minimising downtime for machinery and contributing to faster, more cost-effective project delivery.

The broader impact of S&Z Australia’s work extends far beyond the tunnelling site. Once completed, the M80 Ring Road Completion and North East Link will remove an estimated 19,000 cars and trucks a day from Greensborough Road. Through traffic will be redirected underground, passing beneath Grimshaw Street, Elder Street, and Watsonia

Road –dramatically reducing congestion and returning local roads to local communities.

In addition, the integration of the North East Link tunnels will create a more cohesive transport network by separating local and long-distance traffic. With dedicated express lanes feeding into the tunnels and improved surface roads for local travel, road users will enjoy shorter travel times, less frustration, and improved road safety.

S&Z Australia’s role in this transformation reflects its growing reputation as a trusted partner in the delivery of critical infrastructure. With deep experience in trenchless technology,

company is playing an increasingly important role in Victoria’s Big Build.

“Whether it’s rail, road, or utility infrastructure, our focus is always on delivering precision outcomes with minimal disruption,” Pound said. “This project is a perfect example of what’s possible when smart engineering meets sustainable construction practices.”

As Melbourne and Victoria continue to grow, projects like the North East Link will be vital in creating a resilient, modern, and future-ready transport network for generations to come.

The

world of HDD Technology

Below the surface

How Lismore quietly future-proofed its sewer network.

It’s not the kind of project that turns heads or sparks public fanfare. There were no ribbon-cutting ceremonies, no before-andafter photos, and few signs of disruption, but an important transformation has taken place beneath the streets of Lismore, NSW, one that is set to deliver long-term benefits to the city’s residents, environment and essential services.

Lismore City Council recently completed a $2.78 million sewer relining program, an infrastructure project aimed at restoring the health of the city’s ageing wastewater network without digging up roads or tearing through neighbourhoods.

By choosing trenchless technology, the council managed to upgrade more than 5km of sewer mains and 1.4km of lateral pipes with minimal surface impact.

The program focused on four key zones: Union Street, Bruxner Crescent, the Lismore Base Hospital precinct, and Heritage Park, areas that were identified as priorities due to pipe condition and usage demands. The goal was to improve performance, prevent failures and extend the lifespan of critical infrastructure.

In locations where trenchless methods were feasible, the upgrades were carried out below ground using two advanced techniques. For lateral pipes, a resin-coated liner was inserted and cured in place. Larger mains, meanwhile, were relined using a spiral wound method. This involved feeding a continuous PVC strip through existing manholes and winding it into the shape of the host pipe.

The result is a new, structurally sound pipe formed entirely within the old one, sealed at

both ends to prevent infiltration and leakage. Robotic cutters were then used to reopen service connections.

This modern approach is designed to significantly reduce the environmental footprint of construction, while boosting hydraulic performance and protecting the network from common issues such as infiltration and root intrusion.

Mayor Steve Krieg called the project a smart investment in Lismore’s future.

“It’s about doing the job right and making sure our sewer network is safer, stronger and better for the next 50 years,” he said.

“These aren’t the kinds of projects people see every day, but they’re absolutely critical. They reduce blockages, emergency callouts and overflows. That means fewer disruptions for homes and businesses – and better outcomes
