Wykamol Damp Proof Membranes:

The Wykamol Range of Damp Proofing Membrane include Wykamol CM3 Membrane and Wykamol CM3-MESH Membrane, both of which are supported by BBA Certification Certificate Number 18/5595.

Other than the distinctive difference in colour, the main difference between these membranes is Wykamol CM3-MESH Membrane has a meshed surface on one side which creates a mechanical key to allow the membrane to be plastered, rendered or to receive dot & dab plasterboard.

Wykamol CM3 Membrane on the other hand has been designed as an alternative to meshed membranes where a meshed surface is NOT required, typically where the wall finish to the damp proof membrane is timber battens, a dry-lining frame or block wall.

Product Range:

Wykamol CM3 Membrane

Wykamol CM3 Waterproof Membrane is a High Quality, 3mm Stud Cavity Drain Membrane suitable for Waterproofing of Walls, Floors, Vaults and Tunnels. With its 3mm Stud, Wykamol CM3 Waterproof Membrane is ideal for when space is tight, such as with stairs or low headroom.

Distinctively Black in colour, Wykamol CM3 Membrane is suitable for in 'Type C' Waterproofing and Damp Proofing Applications while delivering a Grade 3 Environment to BS8102:2009 and NHBC Chapter 5.4.

Wykamol CM3 MESH Membrane

Wykamol CM3 MESH Waterproof Membrane is a High Quality, 3mm Stud, Damp Proof Meshed Membrane comprising of HDPE Membrane with a rot-proof HDPE mesh on the surface of one side, perfect for damp proofing. The meshed surface creates a mechanical key to allow the membrane to be plastered, rendered or to receive dot & dab plasterboard.

Fixing Plugs

For Fixing Wykamol CM3 Membrane to the wall, we recommend using the Wykamol CM Brick Plugs (With Seals).

When Fixing Wykamol CM3 MESH Membrane, either Wykamol Plaster Membrane Plugs or Wykamol Ultimate Plaster Membrane Plugs should be used.

Membrane Sealing Tapes

We supply a range of tapes compatible with our range of Wykamol Damp Proof Membranes.

When applying Wykamol CM3 Membrane, use Wykamol Corner Strip Tape for sealing over any 'butted' joins on the membrane. Wykamol Membrane Tape can also be used for any overlapping joins.

When applying Wykamol CM3 MESH Membrane, use Wykamol Mesh Tape when over-sealing any 'butted' joins on the membrane. This tape is manufactured with a 'Fleece' surface which provides a 'key' for plastering and rendering over.

Wykamol Rope may be used to either wrap around the head of fixing plugs in a membrane application, giving the fixing a waterproof seal. It can also be used to form a seal at the overlap of adjacent sheets of Wykamol Membranes when neither a flange joint of stud into stud joint has been made.
