Proofex Cavitydrain

Description

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.

Proofex Cavitydrain is used where sub-structures are constructed in concrete designed to minimize water entry in accordance with BS 8102, Type C. 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.

Fixing:

Hammer-in steel anchors or Hilti XSW 30 fasteners are recommended. Fixing centres: 1000 mm.

Joint laps:

25 mm minimum overlap between sheets is recommended.
