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 & VOCs. 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 Verification Program
Conforming with all relevant European Standards
BS 8485:2015+A1:2019 , CIRIA 735 (2014), International Radon Measurement Association & ISO EN 9001:2015
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 BS 8485:2015+A1:2019 – this superseded all previous guidance.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 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.

Independent Ground Gas Protection Verification Services
The British Standard for Good Practice on Gas Membrane Testing and Verification Of Protection System for Buildings against Hazardous Ground Gases, BS 8485 was updated in 2015 and now BS 8485+A1;2019 replaces all prior guidance.
BS 8485.2015+A1:2019 is in operation alongside the CIRIA 735 Code of Practice and states Independent Membrane Verification and Testing Programs, are equally as important as the design and installation process.
Ensure Your Projects Meet Current Requirements
Many contractors are unaware of the British Standards’ and CIRIA’s advances. This can lead to projects not meeting current requirements. GeoShield Limited ensures all contracts are in accordance:
- BS 8485:2015+A1:2019
- CIRIA 735 (2014)
- CL:AIRE RB17 (2012)
BS 8485 + A1:2019 defines the codes that regulate the installation of gas proof membranes. Independent inspection is mandatory depending on the project risks and criteria.
GeoShield covers all aspects of gas membrane testing, verification, and design from inception right through to completion.
As part of the overall project strategy, Independent Testing and Membrane Verification programs are necessary. Backup documentation is needed and a hand-over package must be included in the final documents.

Radon Gas Ingress In The Workplace
GeoShield GSR+ Tech Program
There is a wide variation in work environments in terms of size and nature, but excessive amounts of Radon gas are not uncommon in almost every kind of environment. There are many factors affecting the amount of Radon collected in a building, such as its location, structure, and how it is used.
The biggest occupational health risk in offices, where hazards are typically low, is Radon. Additionally, employees who live close to the workplace may also be exposed to high Radon levels. Staff members can benefit from a better understanding of Radon.
GeoShield has created GSR+ TECH Program, a RADON monitoring strategy specifically to evaluate the effects of RADON in the workplace. Typical high profile categories include:
- Schools
- Hospitals
- Public Buildings
- Universities
The GSR+ TECH monitoring program is a comprehensive strategy that is tailored to each individual project. GeoShield uses the most technically advanced equipment combined with their experience when performing commercial Radon testing so that they can produce custom handover packages which provides the most accurate picture of RADON gas ingress in the workplace.

Systems Protecting Against Radon Gas Ingress Into New Constructions
GeoShield GSR+ Program
Home Builders & Main Contractors need to ensure comprehensive measures have been taken when protecting against RADON gas ingress, to provide evidence of this important activity GeoShield have formulated the GSR+ Quality Assurance Program.
GSR+ Quality Assurance Program
The GSR+ Quality Assurance Program is a comprehensive hand-over document created for house builders and developers to pass to future owners. GSR+ provides new buyers with a historical log of the protection system application, ensures peace of mind and assists in conveyancing. The GSR+ comprises:
- The Radon Protection Design & Validation
- Relevant Information from BRE 211
- Independent Verification of the Installation
- Test Results of Radon Monitoring (3 months testing)
- GeoShield Validation Certificate
- Desk Top Evaluation of Sub-Floor Ventilation
The comprehensive GSR+ Verification Program is UN-PARALLELED in the new build construction industry.
