Ground Gas Protection Services in the UK

Protecting Developments Through Expert Ground Gas Risk Management

At UKRS, we provide a complete suite of ground gas design and verification services — from initial risk assessment through to on-site inspection and final validation.
Our work ensures that all gas protection measures are fit for purpose, installed correctly, and compliant with the latest UK standards.

Ground gases such as methane (CH₄), carbon dioxide (CO₂), radon, hydrogen sulphide (H₂S), and volatile organic compounds (VOCs) can migrate from contaminated or naturally gassing ground into structures.
If left unmanaged, these gases can present serious risks to human health, building integrity, and long-term asset value.

Our goal is to provide safe, compliant, and cost-effective solutions that give developers, contractors, and regulators total confidence at every stage of the project.

Ground Gas Risk Assessment & Design

Every successful gas protection system starts with a sound design.

UKRS engineers are experienced in assessing site conditions, interpreting gas monitoring data, and developing practical protection strategies tailored to your project’s needs.

Our Ground Gas Design Services Include:

Preliminary and detailed gas risk assessment in accordance with CIRIA C665 and BS 8485
Characterisation of gas regime from site investigation data
Determination of gas protection requirements (points scoring and design selection)
Design of passive and active gas protection systems
Specification of membranes, venting layers, and interface details
Production of gas protection design drawings and specifications
Design reviews for planning or warranty submissions

We collaborate with your design team, contractors, and regulators to ensure gas protection measures are appropriate, buildable, and verifiable.

Ground Gas Verification & Validation

Once a design is approved and implemented, independent verification is essential.

Our verification services confirm that protection measures are installed correctly, sealed effectively, and fully documented in line with industry expectations.

Our Verification Services Include:

On-site inspection and monitoring during installation
Verification of membranes, venting systems, and seals
Integrity testing (e.g., smoke testing, vacuum decay, or dielectric spark testing)
Photographic and written evidence collection
Compilation of verification and validation reports
Independent certification for planners, regulators, and warranty providers

All verification is carried out in accordance with:

CIRIA C735 – Good practice on the testing and verification of protection systems for buildings against hazardous ground gases
BS 8485 – Code of practice for the design of protective measures for methane and carbon dioxide ground gases for new buildings
