Description:
Proofex Cavitydrain membranes are cuspated rolls designed to permit high water flow through a permanent void against the sub-structure face. A range of grades are available.
Proofex Cavitydrain 80 is a space saving solution for vertical applications in conjunction with internal lockwork walls and dry lining systems.

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.

Advantages:

• Suitable for new and existing construction projects
•  Acceptable for all water table classifications (low, variable, high) as per Table 1 of BS8102-2009
• Eliminates increase in structural load due to water pressure.
• Provides a maintainable form of ingress protection.
• Can be specified in conjunction with a monitoring system to provide automatic alerts in the event of pump failure.
•  Internal application in a controlled environment reduces risk of defective installation
• Provides a continuous drainage pathway and vapour barrier
•  Minimal deformation under load maintains drainage performance
•  Conical voids enable high load transfer to structural elements
•  Chemically resistant, unaffected by contaminated substrates and water.
