Ground Gas Investigations and Risk Assessments

Coopers undertake ground gas investigations in accordance with CIRIA C665 and CIEH Local Authority Guide to Ground Gas (September 2008).

The conceptual model for a ground gas risk assessment will determine the likely sources of ground gas (landfill, peat, coal mine or fill strata derived) and hence the recommended borehole array to be installed across the site. The monitoring period over which the boreholes are analysed will be determined by the anticipated source of ground gas.

We utilise fully calibrated MiniRAE PID and Geotechnical Instruments GA2000 for ground gas monitoring.

The results of the ground gas investigation are assessed using CIRIA C665 and NHBC 10627-R01(04). Where vapours are encountered, they are risk assessed utilising appropriate software in conjunction with the Environment Agency R&D Tech Report P5-018/TR (soon to be superseded).

Ground gas mitigation measures are determined by Coopers and robust construction details produced for the proposed development.

We provide a service during the course of the ground investigation to determine whether or not a site is likely to be affected by Radon. If mitigation measures are required, robust details are supplied within the report.
