Membrane products

No two basements are the same and naturally there are a range of waterproofing solutions suitable for each environment. In general there are two main methods used-membranes or structural waterproofing (tanking).

Wykamol’s high quality Cavity Drainage membranes provide an air gap between the membrane and the wall, which allows any free water to run behind it. The membrane is mechanically fixed to the original sound wall surfaces then overlaid with treated battens or other framing systems, on to which plasterboard can be fixed. In some circumstances the battens can be omitted and plasterboard and membrane fixed using special plastic plugs, alternatively a wet plaster could be applied.

Wykamol has an extensive range of membrane types, from shallow studded ‘Slimline’ profiles to deep cavity (20 mm) flooring products which allows a wide variety of situations to be dealt providing tailored solutions. The final choice of membrane is determined by two factors:

1. the finish required and
2. the anticipated flow rate.

Since the introduction of the British Standard for water proofing structures below ground (BS 8102:2009) the use of cavity drain membranes has become the most popular form of structural waterproofing in the UK. Our systems can easily deal with aggressive ground water conditions, where basements are liable to flooding, or indeed where simple dampness, contamination or salting problems are prevalent. Other more diverse applications include turf covered roofs, barn conversions, tunnel linings or even a barrier against radon gas.

As there is little or no preparation required for the membrane system it is very quick to install. When dry finishes are used the system is a “fast track” solution. Decoration does not need to be delayed and there is no drying process.

The Wykamol membrane system has been used successfully in many situations in the UK - from small domestic basements up to major waterproofing projects such as the London Underground stations. There is rarely a dampness or water ingress problem that falls outside the scope of the capabilities of the Wykamol system.
