Cardboard void former is a honeycomb cardboard sheet designed to support the weight of wet concrete and then break down over time to form a void under the concrete. The void created reduces the risk of reactive soils impacting the slab or causing damage to the structure in the future.
This product is “bagged”. As the void former is designed to break down with moisture, exposure to moisture prior to installation can cause the void former to break down prematurely. We highly recommend purchasing the bagged version as this will protect the void former during transport, on-site, and before the concrete has been placed.
