HomeProductsGround Gas ProtectionProtech GM Super
Protech GM Super Gas Membrane is a reinforced LDPE, loose - laid, gas barrier that incorporates an aluminium foil layer to provide maximum protection from the ingress of Methane, Carbon Dioxide and Radon in new developments. The membrane is fully compliant with the recommendations made in Ciria 665, BS8485 and The Local Authority Ground Gas Handbook when installed in accordance with BRE 414.
Protech GM Super is a high performance proprietary reinforced gas barrier that has been specifically designed to conform with the latest guidance documents. Due to its unique composition, the membrane is extremely robust and flexible and, as a result, easy to install on site. The membrane also provides protection from damp and, therefore, there is no need to install a separate DPM.
Full range of accessories to ensure that the membrane is gas tight
Aluminium Core for reduced methane permeability on higher risk sites
Reinforced for superior tear resistance and reduced elongation
Compatible with the Provoid Gas Venting System
Manufactured from High Grade Virgin Polymer
Gas protection systems are critical in developments constructed on sites affected by permanent
ground gas and/or volatile organic compound (VOC) contamination. Systems are designed using the
methodology which is set out in various advisory documents and legislation. The primary purpose is
the prevention of hazardous gases and contaminants from the underlying soils that may cause harm
to occupiers. A well-designed system should also perform the function of a damp-proof membrane,
assisting in preventing the uptake of moisture into the construction.
Whatever your requirement, our head office team of highly trained specialists is on hand to provide
technical advice to assist in all aspects of designing gas protection systems. From recommending the
ideal level of protection for a particular site, through to selection of suitable materials, and advice on
detailing, our team will work with you to ensure that all elements are covered.
As part of providing this complete service to customers, we have developed relationships with strategic
partners; these include:
• Consultants specialising in all aspects of gas protection system design
• Specialist installation sub-contractors
