WallVoid products provide temporary support systems for liquid concrete until the concrete sets and can support itself. They are ideal for concrete components that span across drilled piers, pads, intermittent footings, as well as other concrete work. The Wallvoid 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.
