Good Practice Gas Membrane Testing and Verification of Protection Systems for Buildings against Hazardous Ground Gases was updated and clarified in 2015 when new standards such as BS8485:2015+A1:2019 were introduced to operate alongside CIRIA C735. These updates emphasized that independent membrane verification is just as critical as the initial design and installation.
As ground gas protection verification becomes increasingly essential in complex developments, project teams in cities such as Edinburgh, Nottingham, Liverpool, and London should involve an independent gas membrane verifier early in the process. This proactive step helps avoid delays, non-compliance, and costly remediation later in the build.
UK Resilient Structures (UKRS) specialises in the verification of gas protection systems, ensuring that your project aligns with UK regulations and satisfies planning and environmental requirements.
We support contractors and design teams by providing full compliance across the following standards:
BS8485 ground gas verification (BS 8485:2015+A1:2019)
CIRIA C735 (2014)
CL:AIRE RB17 (2012)
These guidelines outline industry best practices for gas membrane verification in the UK, including the critical need for QA/QC inspections, robust documentation, and professional oversight during ground gas barrier installation checks.
As part of our comprehensive geo-environmental gas verification services, UKRS delivers end-to-end support backed by Professional Indemnity Insurance, including:
Ground gas risk assessment and CSM ground gas assessment
Strategy planning and pre-verification documentation
On-site ground gas testing services and membrane inspections
Final ground gas compliance reports with photographic and field evidence
Radon and methane verification UK and contaminated land gas verification
Early integration of a ground gas monitoring services UK partner is often a planning condition and can significantly improve the long-term performance and approval rate of your development. Our services are available across the UK, including Manchester, Glasgow, Sheffield, and Birmingham, ensuring consistent compliance and confidence for developers, environmental consultants, and local authorities.
