Description:
Proofex Cavitydrain SF is a damp proofing membrane applied to internal floor surfaces in above ground areas. Proofex Cavitydrain SF can be formed around external and internal corners.

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.
• 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
•  Vertical and horizontal
• Internal application in a controlled environment reduces risk of defective installation
