Geophysical GPR Surveys
Geophysical GPR Surveys
Non-invasive underground utility mapping serves as GEOTEC’s core business, where GEOTEC have over 25 years of experience.
Ground Penetrating Radar (GPR) is a versatile tool which can be used to meet a range of objectives:
- Buried services and utilities, in particular drainage, culverts and plastic pipes
- Changes in density relating to voiding or unconsolidated ground.
- The presence of subsurface features such as obstructions, tanks, pile caps and building lines
- Saturated ground conditions and wash associated with leaks
- Graves, crypts, tombs, basements and cellars
- Reinforcing and rebar in concrete slabs and concrete thicknesses
We use a range of GPR antennae in order to search for features at a variety of depths in order to best meet your needs
- Handheld GPR system 0-450mm (below ground level)
- Shallow antenna 0-1m
- Standard antenna 0.1-3m
- Deeper antenna 2-10m
- Dual frequency antenna

We also use GPR when carrying out PAS 128 and buried services / utility mapping surveys as a matter of course, examples below:

This tool also allows us to confirm the presence of metallic and conductive services that have already been detected through radio frequency detection / electro-magnetic locating (RFD / EML).
