Gas and hydrocarbon barrier.
A multi-layer, flexible polyethylene membrane, designed to protect against radon, methane, carbon dioxide, ground gas, hydrocarbon, volatile organic compounds (VOCs), air and moisture.
The barrier also acts as a damp-proof membrane (DPM) designed to withstand the most aggressive environments.
Suitable for use on sites previously used as petrol stations, coalfields, landfill sites, contaminated industrial sites, fracking sites and heavily contaminated areas.
