Radon is a naturally occurring radioactive gas formed by the breakdown of uranium and radium.
Carbon Dioxide is a colourless, odourless gas formed as a by-product of decomposing organic matter.
Methane is a colourless, odourless, flammable gas formed as a by-product of organic material breakdown.

GPS Total Gas Barrier is a multi-layer, low-density polyethylene membrane, reinforced with a polypropylene reinforcing grid with an integral aluminium foil.

GPS Total Gas Barrier is specifically designed and manufactured to perform as a methane, carbon dioxide, radon ground gas, volatile organic compound and air & moisture protection system.

GPS Total Gas Barrier complies with the latest codes of practice as published by BRE, CIRIA and BSI (BS 8485:2015). Suitable for use as gas protection for NHBC GREEN, AMBER 1, and AMBER 2 site characterisations.

Available in a standard roll size of 2m x 50m.


The performance of gas membranes is heavily dependent on the quality and design of the installation, resistance to damage after installation and the integrity of the joints (BS 8485)
