Geophysical Survey Specialists
Complex Geophysics delivered by Down to Earth people
TerraDat is a trusted, multi-disciplinary geophysical survey company with over 30 years of experience. From our HQ in Wales (and also from satellite offices in Scotland, Spain, Italy and Austria), we work with engineers & consultants to deliver 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 design surveys that provide the necessary information and insights to help our customers understand the subsurface.
Our team of geophysics specialists, combined with our state-of-the-art technology, maximises the chance of achieving successful survey outcomes – meaning 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 or GIS formats, and integrated with other site data, such as historical desk studies and geological insights, to give the full 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, contact us for a no-obligation chat to work out exactly what’s needed.
We’re down-to-earth passionate earth scientists, easy to work with, and 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 [...]
