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
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
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
Ground Conductivity (EM)
A ground conductivity or electromagnetic (EM) survey involves the generation of an EM field at the surface and subsequent measuring of the response as it propagates through the subsurface. The main components of the instrument are a transmitter coil (to … Read More
River Crossings: Profiling Geology using Geophysics
Many of our clients constructing roads, laying pipelines or investigating historic bridges find profiling the geology beneath rivers tricky using conventional ground investigation methods. Since the path rivers take is often dictated by changes in geology, the problem can be … 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
Solar Energy: Investigating the Subsurface Beneath Solar Farms Using Geophysics
Click for more information on investigations for Solar Farms Archaeology beneath solar farms TerraDat provides geophysical services to the renewable energy industry, including wind and solar farms. We employ techniques for investigating the ground beneath these developments to assist with … Read More
GeoVoyager: A Collaboration with the Royal Society and Cowbridge School
We’re pleased to announce a partnership with Cowbridge School for an innovative educational project called GeoVoyager. The collaboration is made possible thanks to a STEM Partnership Grant from The Royal Society, the oldest scientific institution in continuous existence since 1660. … Read More
