The Evolution Gas Damp Proof Course was developed for all masonry wall construction types and is manufactured at 0.5mm thick using latest co-extrusion technology to produce a flexible 14-layer combination of high-performance engineering polymers that cannot de-laminate containing 2 independent layers of gas resistant polymer (EVOH) to offer exceptional gas protection and moisture resistance into buildings.

The Evolution GAS DPC provides gas resistance, robustness, and exceptional strength without the requirement for reinforcement or containing aluminium layers and will maintain maximum durability in application.  It is supplied in 20mtr rolls and in standard widths 300mm, 450mm, 550mm, 600mm, 650mm, 750mm, 900mm and 1200mm. The system incorporates an extensive range of preformed components to maintain the integrity of the system to be installed in accordance with the relevant sections of BS 8215:1991, PD6697:2019 and BS 8000-3:2020 and joined using sealing tapes or easily heat sealed/welded for VOC applications.
