Gas membrane installation

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

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.
