Some of our Customers
Mapping Shallow Abandoned Mineworkings using Geophysics
The problem of mapping shallow abandoned mine workings is significant in the re-development of brownfield sites or land reclamation in former mining areas. A TerraDat Geophysics survey can mitigate the risks of mapping mine workings using conventional ground investigation methods. … Read More
How can geophysical techniques be used to investigate and monitor leaking dams?
Dams are vital structures that contribute to vital infrastructure including drinking water, crop irrigation, and hydroelectric power. These structures, often over a century old are also put under huge stress by the large quantities of water they retain as well … Read More
Electrical Earthing: Advanced Soil Resistivity Measurements for Electrical Earthing Design
As part of our services for energy and infrastructure, TerraDat regularly carries out soil resistivity measurements for earthing installation design and corrosion engineering. These resistivity measurements are made by passing a DC electrical current through the ground using a pair … Read More

TerraDat’s approach uses our fully-trained geophysicists to deal with the geophysics while our … Read More
Geophysics for Mapping Geology along Pipeline Routes
Pipelines and cable routes present a set of unique developmental and geotechnical challenges. TerraDat has designed an integrated survey approach, providing data useful to all stages of the project design. Archaeological assessments and UXO detection: Due to the large distances … Read More
Brownfield Site Investigation using Geophysics
Most former industrial sites have a legacy of buried structural hazards and contamination. Geophysical surveys can detect buried targets without the need to excavate. Many industrial contaminants, such as salinisation by acids and hydrocarbon plumes, can leave a significant geophysical … Read More
Crosshole Seismics
Seismic methods can provide detailed information about rock properties and geological structure between boreholes. Fewer boreholes are needed to achieve a continuous picture of the subsurface, thereby reducing overall costs and the risk of missing target features. Borehole seismic methods … Read More
Characterisation of Landfill Sites using Geophysics
Addressing the growing challenge of environmentally compliant landfill management, TerraDat provides expert geophysical survey services for both active and closed landfill sites. Our advanced, non-invasive techniques deliver high-resolution insights into landfill composition and boundaries, surpassing traditional methods in efficiency and … Read More
Meet Bison “Thumper” – our seismic weight drop…
TerraDat’s expertise in shallow seismic surveying to profile bedrock and map changes in subsurface engineering properties goes to another level with the recent acquisition of a powerful weight drop source. As far as we know, it’s the only one of … Read More
