Forming in the rain

Sonoco water-resistant concrete forming tube with RainGuard technologySonoco has re-engineered its water-resistant Sonotube concrete form with new RainGuard technology.

The new-generation Sonotube forms incorporate a proprietary, high-strength, water-resistant paper that allows contractors to set them in wet weather and pour concrete the next day. The fiber forms boast improved strength, toughness and durability in wet conditions, resulting in superior strength-to-weight properties and the virtual elimination of “blowouts” — the most frequent mode of failure of wet fiber concrete forms. What’s more, fiber forms are cheap compared to other types of column forms.

RainGuard technology has been incorporated into all existing types and sizes of Sonotube brand forms, including both round and square forms, as well as Sonotube Finish Free concrete forms.
