A practical guidance tool for safer delivery
Developed by leading industry specialists and driven by the Offsite Alliance Technical Group, this Ground Gas Protection Best Practice Guide has been created as a practical tool to support those responsible for designing, specifying, manufacturing, installing, and assuring buildings where ground gas protection is required.
As construction moves towards more industrialised and manufacturing-led delivery, ground gas protection is too often approached using assumptions and details developed for traditional, site-led construction. This guidance helps bridge that gap by focusing on how systems are actually designed, built, and verified in practice.
The guide is intended to be used during project planning, design development, and delivery, helping teams avoid over-design, reduce risk, and improve buildability while maintaining safety and compliance.
This guidance tool includes:
Clear explanation of ground gas risks, including methane, carbon dioxide, radon and VOCs
Practical design considerations for modular and panelised systems
Guidance on membrane location, material selection and integration
Verification, training and warranty provider considerations
Real-world case studies highlighting common challenges and lessons learned
Who it is for:
Designers, manufacturers, specifiers, installers, verifiers, warranty providers and clients working within offsite and industrialised construction.
This guidance is intended to support competent professionals and should be used alongside relevant industry standards.
