Keytec GP-TITAN-BOND- Gas and Hydrocarbon Barrier is a multi-layer, polyethylene membrane with an bonded textile for pre-applied applications; specifically designed and manufactured to perform as a Methane, Carbon Dioxide, Radon, Ground Gas, VOC, Air & Moisture, and Hydrocarbon protection system.

Keytec GP-TITAN-BOND is a pre-applied waterproofing membrane comprised of GP-TITAN and a specialist bonded geotextile to provide a bonding layer for poured concrete specifically for waterproofing applications (TYPE A BARRIER). The product is available in roll format, 1.0 x 20m and as detailing strip at 0.3m x 20m (other dimensions available on request) in black and white colour.

Keytec GP-TITAN-BOND Hydrocarbon Barrier offers a safe solution for the protection of buildings and occupiers against all levels of hydrocarbons, methane, carbon dioxide and radon ingress. Typically these are sites previously used as petrol stations, coalfields, landfill sites, contaminated industrial sites, Fracking sites and heavily contaminated sites. The membrane also acts as a damp-proof membrane. GP-TITAN-BOND is designed to withstand the most aggressive environments. Testing has been completed in accordance with BS8485:2015 and C748 to determine the permeation rates for Methane, Carbon Dioxide and a range of VOC’s. Immersion testing has also been completed too for Chemical Resistance to EN 14414 and EN 14415.

Roll weights can be in excess of 20kg and hence appropriate care and equipment is required for unloading and handling. This product is non-toxic nor flammable.
