Jablite Claymaster (Clay Heave Protection) is a BBA certified product that provides protection against clay heave.

Claymaster is an EPS compressible-fill material which can be used to prevent potential problems in foundations due to moisture movement in soils which contain a large proportion of mineral particles below 0.002mm.

Jablite Claymaster works by surrounding the pile cap with a layer of low density, compressible, expanded polystyrene, reducing pressure on the ground beams as the surrounding clay expands and contracts.

The material can also be used as permanent shuttering for cast in-situ reinforced concrete, reducing pressure on ground beams in piled foundations, and on the sides of trench fills.
