Some of our Customers
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
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
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
Wind Farms: Investigation the Subsurface for Wind Farm Projects
Over recent years TerraDat have gained a wealth of experience providing geophysical services to the wind energy industry. By working alongside many major wind farm developers TerraDat have developed a suite of geophysical techniques ideally suited to the needs of … 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
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
Experts in Microgravity Surveys
A TerraDat microgravity survey is based on measuring localised variations in the Earth’s gravitational field using an extremely sensitive gravity meter. We own and operate the latest Scintrex gravimeters. A microgravity survey targets physical contrasts between materials of contrasting density. … Read More
