“ Waterproof ” Carton Forms for Grade Beams / Wall Beams & Concrete Slabs

Using the information provided in ACI—347 & ACI—347—SP—4) Guide to Form Work, The SuperVoid products are designed to help us meet and exceed these important guidelines. Void Forming is “Serious Business”, thus we have created the SuperVoid.


The SuperVoid products provide a unique and dependable void forming method, with safe and certain results every time.  The dangers of Expansive Soils, are the volumetric changes, increases/decreases in soil volume. These changes are most often due to climatic changes affecting the underlying soil moisture levels.


As these soil changes occur with resulting increased volumes, the soils expand primarily upwards towards the surface. This creates upward pressure, this pressure causes the SuperVoid products to lose vertical strength. As designed, the pressure mechanically deforms, bends, crumples, crushes the SuperVoid, providing structural protection as a medium of isolation from the potential impact of expansive soils and otherwise damaging uplift pressures.
