Innovation built on experience
ProctorGeo Gas Barrier 2000 is a low-density, polythene gas barrier and damp-proof membrane in concrete ground floors, above and below the slab not subject to hydrostatic pressure, to protect the building against moisture, radon, methane and carbon dioxide from the ground.
ProctorGeo Gas Barrier 2000 is satisfactory for use as a gas-resistant barrier to restrict the ingress of radon, methane and carbon dioxide gases into building from landfill and naturally occurring sources.
