For use as a proprietary floor membrane that will resist ground moisture and rising damp. The membrane is suitable for use in most domestic, commercial and industrial buildings that are not subject to hydrostatic pressure. The 300 and 500 micron membranes meet the requirements for use as a gas control membrane against radon or on gas contaminated land in accordance with the recommendations published by the Building Research Establishment (BRE) and the Building Regulations (E&W).

Description

High performance damp proof membrane which is manufactured from a blown film of extruded low-density polyethylene, suitable for use in concrete floors and structures where hydrostatic pressure is not encountered. Hydroprufe DPM is available in a range of nominal thicknesses to suit a wide range of applications.


Ancillary components:

Can be used with the following to create a complete membrane solution:
