MemTech M1 is a flexible, loose-laid ground gas barrier membrane made from a low-density polyethylene membrane which incorporates a polypropylene reinforcement grid and a foil core layer.

It can be used as a gas barrier and damp proof membrane for application on concrete ground floors, above and below the slab (not subject to hydrostatic pressure), to protect a structure against moisture, radon, methane and carbon dioxide contaminates from the ground.
