Visqueen CM8 Membrane is a 8mm studded cavity membrane formed from 0.45mm thick high density polyethylene (HDPE). The cavity membrane is translucent off-white in colour and supplied in rolls, 2m x 20m which includes an 85mm stud free overlap flange along the length of the roll.

Visqueen CM8HD Membrane is an 8mm studded high density variant that can be used as part of a radon protection system. The membrane is 2m x 20m.

Usage
Type C waterproofing is defined in BS 8102:2022 as ‘drained protection’. This is achieved by the incorporation of a drained cavity within the below ground structure. The walls and floor must provide enough primary resistance to water ingress to ensure the cavity only accepts a controlled amount of water or dampness. Water is collected in the cavity, between the external wall/floor and an internal lining (cavity membranes), and diverted to a suitable drainage point.

Visqueen CM8 Membrane is used as an internally applied vertical membrane as part of a Visqueen cavity drainage system. However in areas where the design permits, the membrane is suitable for use for both horizontal and vertical substrates.

The membrane system is used for damp proofing and internally waterproofing new or retrofit substructure build projects such as the walls (and floors where the design permits) of basements, vaulted ceilings, retaining walls, and tunnels.

The membrane system causes little or no damage to the existing structure making it suitable for heritage buildings and conservation projects.

When used as part of a Visqueen cavity membrane and drainage system, Visqueen CM8 Membrane is suitable for structures requiring Grades 1, 2 or 3 waterproofing protection.

The Visqueen cavity membrane and drainage system can also be used in conjunction with Visqueen Type A or Type B waterproofing protection systems where combined protection is required.
