Reliable void Forms

A solution to expansive soils

Invented With the help of engineers and contractors 

Our patented molded pulp void form is made from 100% recycled waste paper. Reliable Void Forms are much stronger than current corrugated paper boxes used to create void space under the concrete slab during the placement and curing process when dry and especially when wet. Reliable Void Forms become slowly weaker over time as moisture is naturally absorbed into the form and additionally the design allows the soil to expand into the form.
