Protech GM Super is a high-performance proprietary reinforced gas barrier, that incorporates a 12-micron aluminium foil layer, for maximum protection against ground-borne gases. This has been specifically designed to conform to the latest guidance documents.

Due to its unique composition, the membrane is extremely robust and flexible and, therefore, 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.
