TerraDat uses state-of-the-art geophysical mapping techniques to map the subsurface. The benefit of geophysics is that it is non-invasive and can rapidly map large areas and reduce the chance of missing buried targets. We’ve been offering our services for over 25 years to clients from the engineering, environmental, energy and construction markets. Here are four case study booklets showing how geophysics can be applied to your ground investigations.
