Membranes

The Wykamol range of cavity drain membranes are high quality waterproof basement tanking materials giving a wide choice of stud height (drainage capacity) and plaster finish (dry lining or wet plaster).

For use on walls, floors, vaults and tunnels with minimal surface preparation required.

Also suitable for external foundation waterproofing and to provide insulated dry lining for walls above ground level which may not be suitable for conventional plaster finishes.

Guidance Notes for Cavity Drain Membranes

CM8

Wykamol CM8 is a medium capacity drainage membrane (4 litres/m2) for floors and walls both above and below ground level.

When used on basement floors it is recommended that perimeter drainage channels are provided to optimise the flow of ground water towards the sump location (see separate data sheet ‘Wykamol Drainage Solutions’).

Kontract 8

Kontract 8 is a high density polyethylene membrane incorporating 8 mm studs which allow the creation of a continuous drainage pathway for water in basement floors and walls and/or the isolation of damp walls above ground level. The dry surface created allows rapid project completion via dry lining and screeding or timber floor finishes.

Kontract Mesh

Kontract Mesh is a high density polyethylene membrane incorporating 8 mm studs which allows the isolation of wet walls above and below ground.

Incorporates a tough HDPE mesh lathing welded to the front face to allow the direct application of various plaster finishes or adhesive ‘dabs’ and plasterboard. Also suitable for use on floors above ground to be screeded or in conjunction with Kontract 8 below ground.

Slimline Mesh

Slimline Mesh is a high density polyethylene membrane incorporating 3mm studs which allows the isolation of wet walls above and below ground. Incorporates a tough HDPE mesh lathing welded to the front face to allow the direct application of various plaster finishes or adhesive ‘dabs’ and plasterboard.

Also suitable for use on floors above ground to be screeded or in conjunction with Kontract 8 below ground.

CM Plaster

Wykamol CM Plaster is a specialist wall membrane for basements and other damp surfaces giving a low-medium drainage capacity (1.84 litres/m2). The 5 mm studs are uniquely designed so that, when the membrane is fixed using CM Plaster Plugs, the walls can be plastered using conventional methods or ‘dot and dab’ plasterboard finishes.

In basements, CM Plaster can be used in combination with CM8/CM20 on the floor. Above ground, the low stud height enables CM Plaster to be used as a remedial re-plastering system following insertion of a DPC where it is necessary to match-up to retained plaster at higher levels.

Kontract 20

Wykamol CM20 is the highest drainage capacity membrane in the CM range giving a void volume of 14 litres/m2.

Suitable for use on floors and walls in very wet situations or where the large stud height is desired to maximize insulation values.

When used on floors CM20 can normally be installed without the need for perimeter drainage channels and, when overlaid with concrete, the large diameter studs will give high point load resistance capabilities (150 kN/m2) to support load bearing walls built off the slab.

CM Floor

Wykamol CM Floor is a low profile membrane (2 mm studs) specially designed for fast-track sealing of damp concrete at ground floor level – no need for extensive surface preparation normally required with liquid DPM systems (epoxies etc.) and no curing times before floor finishes can be applied. It may also be used on basement floors where the low stud height is critical to maintain ceiling clearance and special measures can be taken to ensure the floor drains freely via drainage channels both around and across the floor.

Wykamol Slimiline

Wykamol Slimline is a tough, damp-proofing membrane that can be laid on top of damp concrete floors or newly laid floor-slabs.

A wide choice of flooring types can then be laid on top, for example, screeds, particle board, and laminated wooden flooring. Insulation can also be used in conjunction with the system, where required.

Kontract Geotex

Wykamol Geotex is a multi-layered cavity drain membrane designed to manage ground water to the land drain, relieving pressure from the structure.

In below-ground waterproofing applications, the primary function of Wykamol Geotex is to divert water away from the structure. It can be act as a barrier against ground gases, like Radon and methane.
