Applied Geophysics & Earth Science Services
Groundsearch applies a comprehensive range of geophysical survey methods to characterise the subsurface for engineering, environmental, and resource applications. Our geoscience services are built on 30 years of field experience across Asia-Pacific — from mineral exploration in remote Cambodia to foundation investigations in urban Singapore.
Our Geophysical Methods
| Method | Description & Applications |
|---|---|
| Electrical Resistivity Tomography (ERT) | 2D and 3D imaging of subsurface resistivity — groundwater, geotechnical, and environmental applications. Depths exceeding 100m. |
| Ground Penetrating Radar (GPR) | High-frequency electromagnetic pulse imaging — utility detection, void mapping, rebar scanning, pavement inspection. |
| Seismic Surveys (MASW / Refraction / Crosshole) | Subsurface velocity measurement — rock depth, soil stiffness, and dynamic foundation parameters. |
| Magnetics Surveys | Total-field and gradient surveys for mineral exploration target generation and buried object detection. |
| Borehole Geophysics | Downhole logging — gamma, resistivity, SP, caliper, acoustic — lithological correlation and aquifer identification. |
| Induced Polarisation (IP) | Chargeability measurements for sulphide mineral detection — gold and base metal exploration. |
