Stylite Clayfill is a low density Expanded Polystyrene (EPS) compressible fill that helps reduce any forces exerted onto deep fill foundations, concrete ground beams and piled foundations. These pressures can be caused by many things, the expansion of clay soils, excess water or overgrowth of tree roots. Whatever the reason for the development of these forces Stylite Clayfill can help absorb the pressure exerted onto the foundations. Our Stylite Clayfill is easy to install and is available in standard thicknesses of 50, 100, 150 and 200mm to accommodate the different levels of ground movement. The compressible fill is also available in pre-cut pile collars to suit the diameter of the pile. EPS is the perfect clay heave protection solution as it is water and rot resistant and will never lose its compressibility.
