Geophysical GPR Surveys
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
Geotec use a range of GPR antennae to search for features at a variety of depths 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

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

Mapping
An example of a survey where several unidentified ground penetrating radar targets are present, along with confirmed buried services and utilities.
This tool also enables confirmation of the presence of metallic and conductive services that have already been detected through radio frequency detection/electromagnetic locating (RFD/EML).
