Clayboard® Residential & Commercial

Clayboard® Residential & Commercial are unique, environmentally friendly void formers and foundation system to protect against clay heave and ground movement. Clayboard® has a 100% recycled and biodegradable paper honeycomb core set between lightweight polypropylene facings which have up to 70% recycled material content. When dry, Clayboard® is strong enough to support the weight of wet concrete and steel reinforcement.

Water is introduced to the Clayboard® core once the concrete slab or beam is set, degrading the Clayboard® honeycomb centre which will ultimately lead to the creation of a void and clay heave protection. This space will accommodate clay expansion without exerting undue pressure on the structure above. The resulting void continues to accommodate natural soil shrinkage and expansion.
