BS 8485:2015+A1:2019 , CIRIA 735 (2014), International Radon Measurement Association & ISO EN 9001:2015

From 2015 construction & design standards Worldwide have started to be reorganised with the objective of eliminating all possible elements that relate to the failure of solutions used to protect against life threatening ground gas ingress into brand-new developments.

The pioneer of these improvements was in the UK with the updated version of the British Standard for Good Practice on the Testing and Verification of Protection Systems for Buildings against Hazardous Ground Gases. BS 8485:2015+A1:2019 , this succeeded all past guidance. BS 8485:2015+A1:2019 operating alongside the CIRIA 735 code of practice ‘Independent Verification & Testing Programs’ has now been harmonised by many EU Countries.

BS 8485:2015+A1:2019 sets the codes of practice that govern the installation of gas membrane systems meant to safeguard against the ingress of Methane, Carbon Dioxide and has annexes concerning Radon & VOC’s.

Depending on the different project criteria independent gas membrane inspection is now usually mandatory to ensure that every effort is made to significantly lower the risk to life.

For projects of CS2 & above (British Standards)/ Amber 2 (NHBC) an Independent Testing and Verification program is needed as an essential component of the project strategy.

The membrane verification company is generally required to be employed preceding development.

GeoShield Limited are founder members of the British Verification Council and are ISO EN 9001 and ISO EN 14001 Accredited.

GeoShields Gas Membrane Validation, Verification & Testing programs are already in progress across Europe including projects in the United Kingdom, Croatia, the Republic of Ireland, Turkey, Belgium, Romania and as far east as the Philippines.

The GeoShield Verification Package is in accordance with all of the insistences made by the British Verification Council including ₤ 2,000,000 PI Insurance that is specific to Verification.
