Ground gas

Ground gas risk assessment

We provide comprehensive ground gas and vapour investigations aligned with CIRIA C665, BS8576, and NHBC recommendations. By developing a preliminary conceptual model during the phase I study or early in the ground gas risk assessment process, we identify potential sources, whether landfill, peat, coal mine, or fill-derived strata, and design a site-specific monitoring regime accordingly.

Advanced monitoring equipment

• MiniRAE 3000 PID: fully calibrated for VOC monitoring, including on-site screening of soils and waters via headspace testing, as well as standpipe installations.
• Geotechnical instruments GA5000: measures oxygen, carbon monoxide, carbon dioxide, hydrogen sulphide, and methane, in addition to flow via an internal flow pod.
