What is Membrane Tanking...
For areas where the internal floor level is below the external ground level, or adjacent to high ground level, the walls are wholly or partially earth retaining. Where it is not possible or practical to lower the external ground, the moisture/dampness from the ground can be blocked by a vertical membrane in the form of a waterproof damp proof barrier (CDM tanking). This membrane is then usually finished with a coat of plasterboard, and skim finished to provide a surface for decoration.
Where very high levels of moisture are suspected a pump and sump unit is also recommended to deposit the excess moisture to a safe area. These products are idea for basement flats and other subterranean structures which need to remain dry.
Where suitable we also offer robust cementatious alternatives such as SIKA and Vandex systems.
