SONOTUBE® ROUND
concrete forms
TRUE. AUTHENTIC. GENUINE.
A heritage of trust
• Outdoor sign, light pole and fence-post bases
Contractors around the world have relied on the Sonotube® brand for over 70 years. More than just paper tubes, Sonotube concrete forms stand strong as the most economical way to create round columns for buildings, entrance ways, structural columns, light posts and other commercial and residential structures.
• Footings
Rain resistance
Applications
• Stub piers for elevated ramps • Columns for residential and commercial buildings and other structures • Flagstones and round steps • Theatrical and movie props • Super-sized shipping tubes
Sonoco engineers applied more than a century of leadership in design, technology and manufacturing to create a high-strength, rain-resistant paper for Sonotube forms. The paper’s attributes allowed Sonoco to reduce the weight of the forms, making them easier to handle, set, strip and discard. And with RainGuard® paper technology, Sonotube forms stand strong even in wet weather. Set today and pour tomorrow.
Industry-leading technology and value The superior strength-to-weight properties of Sonotube forms prevent blowouts and may eliminate the need to use a crane during setup. Contractors around the world know Sonotube concrete forms stand strong in their superior technology and value.
Advantages • Rain-resistant technology keeps wet weather from impacting your pour. • Easier to setup and brace so multiple columns can be poured at one time.
On the Job
• Superior strength-to-weight properties prevent blowouts.
• Easy to cut and drill at the job site. • Heat resistance eliminates form deformation during the pour. • Sonoco manufactures and distributes Sonotube brand concrete forms throughout North America, minimizing lead times.
Important instructions for field use How to store
Store Sonotube concrete forms in a dry place at the job site: • For best results, store forms vertically to maintain roundness. • Keep ends covered at all times. • If stored horizontally, elevate a minimum of 4 inches off the ground and support the full length of the forms.
Placing
Even the largest Sonotube brand forms are easier to place either manually with block and tackle, or by crane: • Position over a reinforcing bar cage if desired. • Avoid damaging the inside surface. • Place individually or in groups for continuous pouring.
Bracing
Sonotube concrete forms require minimal bracing to be brought to plumb: • Use light lumber or scaffolding. • Secure the column foot with collars if necessary. • If pouring bents for bridges, consider tying the column form in with the beam form. Sonotube concrete forms can also be tied into other forms or structural members.
Pouring NOTE: Use of a release agent is recommended with all Sonotube forms, especially when working with aggressive concrete formulations. Sonotube concrete forms are engineered not to buckle, swell or lose shape. Sold in standard lengths of 12', Sonotube concrete forms are designed to be poured in a single lift. Do not exceed ACI-recommended pour rates. Concrete must be vibrated during pour.
Stripping
If stripping is required, strip the form as soon as possible after the concrete has set to prevent concrete from sticking to the form. Recommended time for the easiest and fastest stripping is 24 to 48 hours after the pour. Sonotube concrete forms should not be left on the column for more than five days. Stripping options: • Use a circular power saw to make two vertical cuts on opposite sides of the form. To prevent marring, make sure the depth of cut is less than form thickness. Remove the form. • Use a utility knife to cut the form from the top down at least 12 inches. Use a broad-bladed tool such as a shovel and short strokes to pry the form away from the column in a spiral motion.
