Ground heave


A compressible fill, low density expanded polystyrene. Used to reduce the pressure exerted on reinforced concrete ground beams or on the vertical face of concrete foundations, caused by the expansion of clay soils (clay heave) during the life of the structure.

Claylite for standard applications with ground beams and in even sided trenches.

Claylite Castellated for fitting under lightweight ground beams.

Claylite Super for extra strength in uneven sided trenches.

Claylite Super Castellated gives added strength and stability over Claylite Castellated.
