Geophysical Survey Specialists
Complex Geophysics delivered by Down to Earth people
TerraDat is one of Europe’s leading geophysical survey companies with over 25 years’ experience. Our headquarters are in South Wales, UK and we have offices in Scotland, Spain, Italy and Austria. We work with engineers & consultants delivering honest, reliable and objective subsurface geophysical mapping services.
At TerraDat, we understand that our clients need reliable and actionable geophysical surveys to help make important decisions. That’s why we only ever recommend a survey design that we believe will provide the information and insight that is needed.
Our team of geophysics specialists combined with our unrivalled in-house collection of geophysical instrumentation are able to combine methodologies that maximise the chances of achieving a successful survey outcome – which means that we can always employ a practical and objective approach.
Our geophysical survey results are always presented in a way that’s easy to understand, in popular CAD/GIS formats, and where possible, integrated with other site data to give the full subsurface picture.
We never forget that it’s our job to use our expertise to help clients achieve their goals, so even if you are unfamiliar with geophysics, our free, no obligation consultancy service will help you get exactly what is needed.
We’re scientists, but are easy to work with and down to earth. And we’re here to help.

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 as significant environmental events. Hence monitoring dams and ensuring their safety is vital. Deformation of dams can occur because of erosion, hydraulic gradients, water load, and water saturation. That can put dams at risk of failure, possibly flooding homes, businesses, and farmland, and putting lives [...]
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 its kind in the UK and has significant benefits over other seismic sources, not least it's power and portability. We acquired the equipment in 2017 and it has undergone extensive refurbishment at our HQ in South Wales. The US-manufactured Bison EWG ‘Thumper’ model 1417-2 2 [...]
How TerraDat’s work is helping monitor climate change
A map of Europe showing the location of the Sierra Nevada mountain range. Courtesy of free maps at https://mapswire.com/countries/spain/. 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 area of permafrost between Svalbard in the north and the Sierra Nevada mountains in Spain in the south. The study, coordinated by Cardiff University and [...]
