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
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
How TerraDat’s work is helping monitor climate change
Twenty years ago, geophysics specialists at TerraDat became involved in a major pan-European project to measure the impact of climate change on permafrost in the mountains of Europe. The PACE (Permafrost And Climate in Europe) Project began monitoring a large … 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
Karst Geology: Void detection & Karst Mapping using Geophysics
TerraDat is regularly contacted by ground engineers asking about our void detection surveys using geophysics. The benefits of our geophysical surveys in terms of maximum area coverage and minimal ground disturbance provide an ideal solution. The best geophysical methods for … 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
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
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
