WallVoid® is a corrugated paper carton form that helps eliminate severe damage to structural concrete grade beams and walls by creating a space between them and underlying expansive soils.
WallVoid® provides temporary support for the placement of liquid concrete until the concrete sets and can support itself. It is used primarily in panel-forming applications, having a panel flange along the bottom edge on which the concrete form rests, which holds the material down and prevents it from floating up into the wall during concrete placement. It is ideal for vertical concrete structures that span across drilled piers, pads, or intermittent footings.
The WallVoid® material, lying under the structural concrete construction, absorbs ground moisture and loses strength after the concrete has set, creating space into which soil can expand without causing damage.
