Verified by manufacturer 4 months ago
BBA Agrément Certificate
Certificate type
High density polyethylene (HDPE) profiled drained cavity former and damp proof membrane.
Application
Proofex Cavitydrain 80 is typically applied to the internal face of basement walls 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.
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.
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.
Features and benefits:
- Resistant to most acids, alkalis, oils and fuels.
- Suitable for new and existing construction projects.
- Acceptable for all water table classifications.
