Where a site has been designated as requiring gas protection measures it is a requirement to ensure these are appropriately validated by an independent verifier. DAM Geotechnical Services have experience in the verification of gas protection systems, including gas resistant membrane validation.  We can also assist with gas protection solutions and correct product specification. 

​

Specifically, we can offer:

​

• Recommendations for gas protection measures as part of a ground gas risk assessment.

• Verification of gas protection systems in line with BS 8485:2015+A1:2019 and CIRIA C735.

• Visual inspections.

• Integrity testing using air lance and tracer gas.

• Verification reporting.
