CCW MiraCLAY is designed for use under reinforced concrete slabs 4″ (100mm) thick or greater on a compacted earth/gravel substrate. If installed over a mud slab, CCW MiraCLAY requires a minimum 5″ (150mm) thick reinforced concrete slab. In addition, a minimum of 2’ of compacted dirt must be over CCW MiraCLAY.
