Clayboard® is unique, environmentally friendly void former and foundation stabiliser developed by Dufaylite. Clayboard® is a biodegradable honeycomb core set between lightweight polypropylene facings.
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 is set, degrading the Clayboard® honeycomb centre which will ultimately lead to the creation of a void. This space will accomodate clay expansion without exerting undue pressure on the structure below.
The resulting void continues to accomodate natural soil shrinkage and expansion.
