Geophysical Survey Company – TerraDat (UK) Ltd
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
CHECK OUT OUR NEW DEDICATED ARCHAEOLOGICAL GEOPHYSICS WEBSITE TerraDat’s archaeological geophysics team is uniquely placed to draw on decades of experience in applied geophysics and archaeological surveying. TerraDat’s approach uses our fully-trained geophysicists to deal with the geophysics while our
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
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.
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
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
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
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
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
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
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
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
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.
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
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
Mapping peat is a common requirement for proposed developments such as wind farms and pipeline routes where they cross remote and/or sensitive areas. There are several geophysical methods that can provide plan and cross-sectional information to map the distribution of
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
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
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.
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
