Cavity drainage membrane

CavityTech Systems Ltd design and install cavity drainage membrane systems within basement construction. This is an effective method of water proofing for both new build and existing basements.

The main benefits of cavity drainage membrane are:

Preparation - As the membrane is mechanically fixed, there is no reliance on the system to bond with the substrate, so preparation is minimal. These membranes can also be applied to more friable backgrounds, which are often not suitable to receive a cementitious rendering type system.
Depressurising the structure - The studded membrane design creates a air cavity between the membrane and the substrate, allowing any moisture to move freely. This depressurises the structure, eliminating weak points and ensures that the problem is not forced elsewhere. The most critical part of the system is the floor/wall junction, where we install suitable drainage channelling, to collect and direct any moisture to a suitable point for exit.
Finishing - A membrane installation is often finished using a dry-lining system, enabling electrical and plumbing services to be concealed, and if required, the inclusion of insulation to increase thermal values. As soon as the membrane / lining systems is installed the basement area will feel instantly warmer and drier. Subsequent decoration can be carried out promptly.
