Sonotube Round Concrete Tubes and Forms

Rain resistance
Sonoco engineers applied a century of leadership in design, technology and manufacturing to create a high-strength, rain-resistant design for Sonotube forms. The new technology allowed Sonoco to reduce the weight of the forms, making them easier to handle, set, strip and discard. And now with RainGuard paper technology,* Sonotube Standard concrete 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 round concrete forms stand strong in their superior technology and value.
