GBG Group Services

We have a range of geophysical services to suit the needs of your projects. With 40+ years of experience globally, we can determine and characterise the details you need on your site. What goes on from a geotechnical perspective of a green or brownfield site? How about the history of an archaeological burial site? What’s the rock profile under off-shore? How can we preserve a heritage-listed building when testing its structure? Whatever your problem is, speak to us about a tailor-made solution for you.

Specialist Techniques

Every technique has its benefits and limitations, and GBG specialises in using different combinations of geophysical techniques to give more thorough investigations of the subsurface. By using multiple techniques, the limitations of one technique can be overcome by another. For example, soil that limits the transmission of Ground Penetrating Radar (GPR) waves can be ideal for the propagation of seismic waves, therefore using Multi-channel Analysis of Surface Waves (MASW) as an additional technique to a mine-shaft location investigation.

Some investigations are best done with one technique that has a high speed of collection but limited results. The results of that technique can then be used to more effectively target another slower technique to give more detailed information at a few key locations. This second dataset calibrates the first and provides a more cost-effective solution.

Each project will require a geophysical plan of action that we will create for you.
