Dufaylite Clayboard

Void formation system
‘’Clayboard’ is a 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.’
