Jablite Claymaster (Clay Heave Protection) is a BBA certified product that provides protection against clay heave.
Shrinkable clays are soils containing a large proportion of mineral particles of less than 0.002mm in diameter. This produces an extremely cohesive soil type when wet, but shrinks to a crumbly, crazed structure when dry. The expansion and contraction process during wet and dry periods is known as ‘clay heave’. This can cause severe problems with foundations.
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.
