Patented cone design allows the soil to expand into the open space. With only 18% of the form in contact with the ground the soil can expand around our cones.

Gausul Hasan, M Sc., E.I.T, tested and proved that soil expands around our form in his thesis study for the University of Texas at San Antonio.
25% of homes in the United States has some damage caused by expansive soils. Expansive soils cause a greater financial loss to property owners than earthquakes, floods, hurricanes & tornadoes combined.
The best protection from expansive soil is creating reliable void space when you build. Saving you the time and hassle of recovery excavation and replacement.
Use a void form you can rely on. Use Reliable Void Forms.
