Since 2015 construction & design standards Internationally have begun to be
restructured with the aim of eliminating all possible factors that relate to the
failure of systems applied to protect against life threatening ground gas
ingress into new constructions. The spearhead of these changes 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 BS 8485:2015+A1:2019 – this superseded all previous guidance.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. GeoShield Validation, Verification & Testing programs are currently
underway across Europe including projects in the United Kingdom, the Republic of
Ireland, Romania, Croatia, Belgium, Turkey and as far east as the Philippines.
BS 8485:2015+A1:2019 sets the codes of practice which govern the installation of
membrane systems designed to protect against the ingress of Methane, Carbon
Dioxide and has annexes regarding Radon & VOC’s. Dependent on the various
project criteria independent inspection is now often mandatory to ensure every
effort is made to minimise the risk to life. GeoShield Limited are founder
members of the British Verification Council and are ISO EN 9001 and ISO EN 14001
Accredited. For projects of CS2 & above (British Standards) / Amber 2 (NHBC) an
Independent Testing and Verification program is required as an integral part of
the project strategy. The Verification Company is usually required to be
employed prior to construction. The GeoShield Verification Package is in
accordance with all insistences made by the British Verification Council
including £2,000,000 PI Insurance that is specific to Verification.
