Geophysical Survey Company – TerraDat (UK) Ltd
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
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
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
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
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
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
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
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
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.
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
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.
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 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
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’
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
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
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
