Product Details

Clayboard Residential is a unique, environmentally friendly void former 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.

  • Has a nominal compressive strength of 30kN/m2 when dry
  • BBA Certified to comply with NHBC Standards.
  • Only to be used for Residential projects
  • Lightweight
  • Cost effective for residential budgets
  • Environmentally Friendly
