Sonotube Premium® Concrete Forms

Sonotube Premium concrete forms leave an impression on you – not the column

New Sonotube Premium concrete forms produce exceptionally smooth columns that require no manual finishing. How? Sonoco applies a patented Duraglas® coating to the inside of its Premium forms, eliminating spiral marks, seams and imperfections that would otherwise be left on the finished surface of the concrete. This results in significant cost savings through the elimination of the labor and materials required to finish columns.

Easier form removal

Sonotube building concrete forms now feature a quick, safe and convenient way to remove the forms after the concrete sets. The RipCord™ stripping filament eliminates the time-consuming process of cutting the form away. Sonotube Finish Free concrete forms are manufactured with the RipCord filament mounted inside the tube. When pulled with a hammer, pry bar or other tool handle, the RipCord strap cuts right through the form wall. Now the form can be removed without marring the surface of the column.

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 technology allowed Sonoco to reduce the weight of the forms, making them easier to handle, set, strip and discard. And now with RainGuard™ technology, Sonotube forms stand strong even in wet weather. Set today and pour tomorrow.
