The Installation of Gas Membranes to buildings is a highly skilled specialised activity and is becoming more of a requirement in the construction Industry of today due to the release of greater amounts of brownfield Land as a consequence of government directives for the construction of a wide range of buildings including homes, industrial units, shops, sports centres etc.
Dangerous ground gases such as radon, methane and carbon dioxide can infiltrate buildings and build up in areas of poor ventilation and create dangerous environments for inhabitants of the buildings which can be harmful to health. Methane is explosive and an asphyxiating gas and carbon dioxide is asphyxiating.
Planning departments and other controlling bodies have become aware of the importance of correct installation of protection measures on construction projects and have subsequently made the installation of gas membranes, by a competent contractor, a

condition of planning. Local authority Contaminated Land Officers are insisting that the appropriate measures and evidence are in place to demonstrate and prove that an appropriate gas membrane has been installed and that this companies with the latest guidelines.
The National House Builders Council (NHBC) is also active in this area and has measures in place to ensure that gas membrane installation has been carried out correctly in the private house building market.
Training in this highly skilled activity was historically limited and tended to be carried out in-house.
By having an industry approved training programme and linking successful completion of this training to the NVQ qualification, the gas membrane sector can promote and demonstrate
compliance and commitment to having a fully qualified and competent workforce which will also be evidenced via the Construction Skills Certification Scheme (CSCS) with the production of an appropriately endorsed CSCS card.
