Claymaster is a compressible-fill material; it is used to prevent potential problems in foundations caused by moisture movement in soils. This occurs in soils which contain a large proportion of mineral particles below 0.002mm.

Claymaster is used as a permanent shuttering for cast in-situ reinforced concrete, reducing pressure on ground beams in piled foundations, and on the side of trench fill.

Cellcore is a composite cellular compressible-fill material; it is used to prevent potential problems in foundations due to moisture movement in soils which contain a large proportion of mineral particles below 0.002mm.

Cellcore is used as a permanent shuttering for cast-in-situ reinforced concrete slabs, piled beams and rafts, reducing upwards pressure due to ground heave.
