Mandatory Requirements For Gas Membrane Testing
In 2015 the British Standard for Good Practice on Gas Membrane Testing and Verification of Protection Systems for Buildings against Hazardous Ground Gases was updated, BS 8485:2015+A1:2019 supersedes all previous guidance.
BS 8485:2015+A1:2019 operating alongside the CIRIA 735 code of practice states Independent Membrane Verification and Testing Programs are as important as the design and installation process.
Many Contractors are unaware of the advances put forth by the British Standards and CIRIA and to how projects may fail to meet current requirements; GeoShield Limited ensure contracts are in accordance with:
BS 8485:2015+A1:2019 sets the codes of practice which govern the installation of gas proof membranes. Dependent on the various project risks and criteria independent inspection is mandatory.
GeoShield provides gas membrane testing and verification requirements from inception to completion.
An Independent Testing and Membrane Verification program is required as an integral part of the project strategy, back-up documentation needs to be in place and hand-over package included in the final documents.
