The standard range of products are available in a variety of depths and grades to suit most commonly encountered combinations of soil heave potential, concrete depth and U-value requirements.
300mm Cellcore HX Plus is specifically engineered to be employed beneath reinforced concrete floor slabs, serving as an insulated solution for ground heave protection.
Please be aware that in order to define the comprehensive product specifications, the initial steps involve determining the appropriate 300mm Cellcore HX depth and grade to counteract potential ground heave while adequately supporting construction loads. Subsequently, the necessary thickness of the Filcor insulation must be calculated to meet the desired U-value requirements.
