Ground Gas Protection
When working within basements or below-ground spaces, assessing and managing ground gases is an important consideration. Gases such as radon, methane and carbon dioxide occur naturally in the ground and can pose health and safety risks if they accumulate within buildings.
These gases can enter structures through cracks in foundations, service penetrations and other openings, making proper assessment and protection measures essential during basement and below-ground construction.
As part of our basement, construction and new build services, we can assist in identifying potential ground gas risks and advising on appropriate protection measures. Where required, we recommend specialist testing and design to ensure your project is safe, compliant and built to the highest standards.
When ground gas protection needs to be considered
Building regulations require that developments on land affected by ground gases are properly assessed and protected against the ingress of harmful gases. Local authorities and regulatory bodies enforce strict requirements where there is a risk of ground gas contamination.
For basement and below-ground construction, it is essential to consider ground gas protection at an early stage in the planning and design process. Identifying potential risks early helps avoid costly design changes, delays and compliance issues later in the project.
Types of ground gases
There are several types of ground gases that can affect basements and below-ground structures, including:
- Radon
- Carbon Dioxide
- Carbon Monoxide
- Nitrogen
- Methane
- Hydrogen Sulphide
- Volatile organic compounds (VOC)
Where you can find specialists
If you are working with us, we can recommend experienced ground gas specialists as part of your project.
Alternatively, if you wish to source a specialist independently, we recommend visiting the UK Radon Council or the Property Care Association (PCA). These organisations can help you find qualified professionals who can assess ground gas risks, provide system designs and specifications, and support installation to ensure compliance with best practice standards.
