Geophysical Survey Company – TerraDat (UK) Ltd
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
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
TerraDat is a specialist Seismic refraction survey company with many years of experience applying and researching its use in shallow engineering and geotechnical work. Seismic survey methods provide a useful tool for investigating geological structure and rock properties. The technique
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
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
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.
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.
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
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
In this interview with Alan Wick, originally broadcast on his radio show, you will hear from TerraDat co-founder Nick Russill about: How to continue to grow your business by innovating and staying agile Why it’s important to sometimes say ‘No’
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
Multi-channel Analysis of Surface Waves (MASW) is a very useful method for investigating shallow geological structure and, in particular, the relative shear strength of subsurface materials. By incorporating density values for the local bedrock and overburden sediments it is possible
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
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
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
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.
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
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.
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
