Geophysical Surveys
Ground Penetrating Radar
GPR is a non-intrusive technique used to image the subsurface. Multiple-frequency antennas detect voids, buried obstructions, and other features by transmitting an electromagnetic pulse into the ground and recording the return signals' strength and timing from various materials below.
Application include:
- Subsurface/geophysical investigations to supplement intrusive methods
- Void detection and location, such as sinkholes, chambers, and septic tanks
- Locating buried tanks or reservoirs
- Identifying large buried objects
- Concrete scanning

Our surveyors would be more than happy to discuss testing with you, whether it is a straight forward site attendance or you have an application requiring a bespoke design.
Please contact a member of our structures or materials testing team for further details.
Electrical Resistivity
Resistivity imaging is widely used to map geological structures within the shallow subsurface. Our non-invasive approach provides continuous and accurate information about subsurface composition, offering a cost-effective alternative to traditional invasive methods.
Example applications:
- General Lithology
- Depth to Bedrock
- Thickness of Strata
- Presence of sinkholes and voids
- Shallow groundwater exploration
- Landfill and contamination zone boundaries
- Archaeological surveys
- Mineral extraction
