Fosroc® Proofex Cavitydrain Waterproof Membrane
Fosroc® Proofex Cavitydrain High density polyethylene drained cavity former for internal waterproofing of substructures Uses Proofex Cavitydrain is used to waterproof below ground structures where Type C (Drained Cavity) protection is required either as the sole protective measure or in conjunction with Type A (Barrier) or Type B (Integral) waterproofing to achieve the required grade of protection in accordance with the recommendations of BS8102-2009. Any water ingress is contained within a free draining cavity and channelled to an appropriate internal water management system so that no pressure forms against the internal linings, thereby providing protection against water ingress into usable spaces.
