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

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
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
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
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
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 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
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
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
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
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
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
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
