2-6mm Carboniferous Limestone (SUDS Sub-Base)
Perfect for the top layer of a permeable sub-base. Placed on the larger 20-5mm material the 2-6mm OGCR carboniferous limestone is ideal for laying your patio blocks, slabs or paviors on. The combination of the carboniferous aggregates will allow the excess water to slowly drain into the ground and not into the already overworked sewers or watercourses.
