Triton TGS – HP750

Triton TGS HP750 is a high performance proprietary reinforced gas (methane, radon and carbon dioxide) barrier, which incorporates a 12 micron aluminium foil layer for maximum protection against ground-borne gases.

The membrane can be used to protect against hydrocarbon vapours when not in direct contact with the ground (above block and beam floor design). Specifically designed to conform to the latest guidance documents. Due to its unique composition, the membrane is extremely robust, flexible and easy-to-install on site. The membrane also provides protection from damp when placed below the slab, and therefore there is no need to install a separate DPM.
