SureVoid® SlabVoid® is a corrugated paper product that helps eliminate severe damage by creating a space between the structural concrete slab and underlying expansive soils.
The SureVoid® material, lying under structural concrete construction, absorbs ground moisture and loses strength only after the concrete has set, creating space into which soil can expand without causing damage. SlabVoid® is designed to withstand the working load of the concrete construction process, then deteriorate with the absorption of moisture.
