Some of our Customers
Experts in Microgravity Surveys
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. … Read More
Aerial LiDAR Survey & UAV Mapping Services
TerraDat has been mapping the world in three dimensions since the earliest days of close-range photogrammetry and terrestrial laser scanning. As drone technology matured, we were at the forefront of integrating airborne LiDAR — and today our UAV-mounted sensor represents … Read More
Ground Conductivity (EM)
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 … Read More
MASW (Surface Wave Surveys)
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 … Read More
Peat Mapping using Geophysics (Peat Surveys)
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 … Read More
Mapping Shallow Abandoned Mineworkings using Geophysics
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. … Read More
River Crossings: Profiling Geology using Geophysics
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 … Read More
Shallow Geophysics for Transmission Cable Route Characterisation
Shallow geophysics plays a crucial role in characterizing the subsurface for transmission cable routes, offering significant advantages to transmission teams working on energy infrastructure projects. By employing non-invasive geophysical techniques, energy providers can optimize cable route planning, reduce environmental impact, … Read More
TerraDat reveals ‘Port Talbot’s Pompeii’ at Margam Park
TerraDat was privileged to conduct the geophysical survey at Margam Country Park that revealed a substantial Roman villa While much of our work involves commercial geophysical surveys for infrastructure and engineering developments, it was wonderful to collaborate closely with archaeologists … Read More
