Why the need for a protective gas barrier combined with damp proof membrane?

The Building Regulations (Approved Document C) require that proper precautions be taken to prevent danger to health and safety when building on contaminated land. However, a number of significant political and economic factors have led to the need for commercial and residential developments to be located on sites with the potential for gas contamination:

Political pressure requiring the reclamation and rehabilitation of former industrial sites, including former gas works.
 
An acute shortage of available inner city and urban sites.
   
Planning consent difficulties in rural locations.

The Solution - Visqueen Gas Barrier

Visqueen Gas Barrier offers a safe solution for the protection of buildings and occupiers against Methane, Radon and Carbon Dioxide. When installed in accordance with the BRE Report:Construction of New Buildings on Gas Contaminated Land, Visqueen Gas Barrier is an essential component of a gas protection system. It is also a fully effective damp proof membrane.

Protection against Radon, Methane, Carbon Dioxide and moisture penetration.

 

What gases are involved?
Three common gases require an integrated foil barrier solution:
 
 Methane
 

Description: an odourless flammable gas that is explosive when released to atmosphere levels as low as 5% and exposed to a source of ignition

 

Where Found: Methane is formed wherever there is below-ground degradation of organic substances e.g. landfill sites, sewage treatment areas, mining localities and peat bogs.

 

Protection: Whole site gas barrier protection is necessary

 
 
 Radon
 

Description: a naturally occurring radioactive gas that is colourless and odourless. Radon is harmless when vented to atmosphere but life-threatening if allowed to accumulate in buildings. Radon is the second largest cause of lung cancer after smoking.

 

Where Found: Large areas of the UK (not just granite areas) are affected.

 

Protection: Building foundation area gas barrier protection is essential.

 
 
 Carbon Dioxide
 

Description: a colourless gas that in high concentrations can result in asphyxiation.

 

Where Found: The gas is formed by the oxidation of carbon compounds such as in land fill sites.

 

Protection: Building foundation area gas barrier protection is recommended.
