Sonotube Plus Concrete 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 Plus concrete forms stand strong even in wet weather. Set today and pour tomorrow.

Finishing

Sonotube Plus give a smooth finish on the column. Sonotube Plus forms have an inliner inside. The inliner is taped at the tube ends to prevent collapsing. Depending on the diameter of the tube, one or more vertical joints will be visible.
