CM8 is manufactured in the UK from high-density polyethylene (HDPE) and is impermeable to water, water vapour and radon gas. The product provides an effective barrier to the transmission of salts or other contaminants from the substrate.­  Typical uses include protection against the effects of water ingress by isolating walls, floors, vaults and tunnels.

The 8mm high membrane has stand-off studs to provide drainage capacity as part of a cavity drain tanking system with provision made for disposing of water build-up behind the membrane to a drainage outlet point or to am pump and sump.

Whilst being extremely robust, it sufficiently compliant to fold neatly around corners and is easy to trim with a standard utility knife.  When tanking walls, special membrane plugs can be used to fix battens in front of the membrane to accommodate a fixed stud wall.  When using on floors it can be used with a concrete screed, insulated screed or with a floating dry board system.
