GPS 2000 is a low permeability, highly robust, monolithic thermoplastic LDPE membrane for use as a radon, carbon dioxide and methane barrier for NHBC AMBER 1 situations. GPS 2000 prevents the transmission of harmful gases. Due to the nature of its construction, the membrane overcomes problems associated with membranes manufactured from post-consumer recycled waste. GPS 2000 also acts as a damp proof membrane and can be heat welded. GPS 2000 fully complies with the recommendations of the Building Research Establishment Document: 414 and with the requirements of NHBC guidance on methane and carbon dioxide report issue 20 for Amber 1 sites.
