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.
