Some of our Customers
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
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
Slope Stability: Understanding Slope Stability using Geophysics
TerraDat has developed a strategy for investigating slope stability that provides key engineering properties for managing and monitoring existing and potential landslides. While each site is considered unique with respect to the survey design, the methods that most often prove … Read More
Magnetics
The magnetic survey technique is based on mapping localised variations in the Earth’s magnetic field caused by sub-surface magnetic materials, which range from naturally occurring magnetic minerals to man-made ferrous objects. This leads to a wide range of applications, from … Read More
Experienced Ground Radar (GPR) Company
TerraDat has been a GPR survey company since the technique evolved to a level where it could be applied to a wide range of applications over 20 years ago. Because the GPR method involves analysis of wave-form data, our experience … Read More
Electrical Resistivity Tomography (ERT)
The Resistivity technique is useful for characterising the sub-surface materials in terms of their electrical properties. Variations in electrical resistivity (or conductivity) typically correlate with variations in lithology, water saturation, fluid conductivity, porosity and permeability, which may be used to … Read More
How we brought the evocative story of Swansea’s copper heritage to life using 3D Reality Capture
An evocative video combining the oral history of one of Wales’ most important industrial sites with a 3D digital model created from laser scan surveys are preserving its heritage for future generations as well as connecting local communities with their … Read More
Seismic Reflection
TerraDat has specialist experience in designing and implementing high-resolution seismic reflection surveys for onshore and shallow marine environments. The company routinely carries out seismic survey work for geotechnical and environmental applications as well as larger-scale work for oil/mineral exploration. … 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
