Subsurface Geotechnical are a leading firm of independent geophysical consultants based in the heart of the historic city of Worcester. We specialise in carrying out geophysical surveys using a variety of geophysics methods for practical applications in site investigation, geoenvironmental surveys, electrical earthing and non-destructive testing. Established in 1985, our company was one of the first UK geophysical consultants to carry out ground penetrating radar surveys commercially. In the intervening years Subsurface Geotechnical have compiled a successful record of geophysical investigations completed in the UK and around the world.

Our geophysical surveys are always carried out by highly qualified geophysicists, not technicians. This allows problems to be solved on-site, by customising data acquisition to the highest levels of technical excellence. Following a comprehensive programme of data processing and interpretation by our team of experts; survey results are presented in an easy to understand engineering CAD format.

Engineering geophysics surveys investigate the physical properties of the ground by the use of specialised equipment. The survey results provide information on subsurface ground conditions that would not be evident from the ground surface, for all types of practical engineering and environmental applications. Geophysical surveys are non-intrusive and non-invasive, and can help to avoid disruption that may be caused by extensive drilling, pitting and trenching. A geophysics investigation can cover large site areas rapidly to provide either reconnaissance data or a detailed investigation, and can optimise the targeting of any essential intrusive inspections. In environments where intrusive ground investigations are not possible, our geophysical surveys can still provide engineers with useful site information.
