Ground Gas Design & Vent Calculations
If your site investigation has found ground gas, you need a gas protection design that meets BS 8485:2015+A1:2019 before building starts. We design gas protection for housing and commercial developments and supply a full set of drawings for your installers and building control. All of our design work is covered by comprehensive Professional Indemnity insurance.
What's included
Our design service includes:
• A review of your site investigation and gas characteristic situation (CS1 to CS6)
• Selecting protection measures that achieve the score BS 8485 requires
• Membrane specification and detailing
• Sub-floor venting design and vent calculations
• Drawings for installation, verification and approvalDesign and verification from one team
Because we also verify installations, our designs are detailed with inspection in mind. That helps avoid problems on site and delays at sign-off.
Standards we design to
