Ground Gas Protection

Ground gas protection is a method used to control and prevent volatile gases penetrating into buildings and structures. It involves the installation of ground gas membranes. These systems are essential in construction projects on land affected by ground gas contamination.

Orchard Preservation work with developers reclaiming unused land to make the environment safe for development and inhabitants. We supply and fit a range of gas membranes and venting solutions. For more information please call us on 01395 233 436.

What are ground gases?

There are a number of ground gases that can pose a health hazard and must be addressed if they are present on development sites. They include:

• Radon
• Hydrocarbons
• Methane
• Carbon Dioxide
• Volatile Organic Compounds (VOCS)

Why are ground gases dangerous?

Ground gases can pose a risk to health. These gases can be highly toxic and some types are carcinogenic. As a result, it is highly important that if such gases are found on a potential development site that steps are taken to minimise risk and reduce or prevent the gases releasing into the atmosphere.

How does radon enter a building?

Radon is a naturally occurring radioactive and carcinogenic gas that can cause lung cancer if exposure levels are too high. Radon gas can enter a home in many ways, including:

• Cracks
• Groundwater
• Windows
• Exposed soil
• Pipe penetrations that are loosely fitted
• Mortar joints
• Wall and floor joints

Ground gas membranes

Ground gas membranes provide the perfect solution to overcome gas contamination issues. We offer a range of solutions and provide a first class service including design support, specification and site support.
