Damp Proof Membranes

Surface DPMs are designed to protect floorcoverings from residual construction moisture and rising dampness, when a structural DPM is missing or damaged. 

What is the purpose of a DPM?

A surface DPM, which bonds to the surface of the concrete, minimises moisture vapour transmission. It, therefore, prevents moisture build-up beneath vinyl or other floor coverings. The installation of a surface DPM is a vital stage in the construction process, for all types of projects. To determine the most suitable and cost-effective surface DPM for any application, it is essential to determine the relative humidity and the moisture vapour transmission rate of the substrate and floor covering.
