BBA Agrément Certificate
High density polyethylene (HDPE) profiled drained cavity former and damp proof membrane.
Proofex Cavitydrain 200 is typically laid onto basement floor slabs 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 BS 8102.
Proofex Cavitydrain is a profiled HDPE membrane with ribbed conical voids spaced to permit high water flow through a permanent void against the sub-structure face.
Any water ingress through the structural concrete will not enter the internal environment because Proofex Cavitydrain provides a continuous water and damp proof drainage former to connect with drainage channels or outlets cast into the floor. Internal application in a controlled environment increases security against waterproofing failure.
