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
Our standard digital hyper-stacking GPR system as part of a Utility Mapping Survey

We primarily use GPR when carrying out PAS 128 and buried services / utility mapping surveys and this system is invaluable in detecting non-conductive and non-metallic buried services and utilities such as plastic water & gas pipes, drainage and culvert routes.

Want to know more about GPR Surveys?

An example of a survey where we have several unidentified ground penetrating radar targets present, as well as confirmed buried services and utilities.

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).

We can combine 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 – this is the primary tool we use for utility mapping surveys 
  • Deeper antenna 2-10m •
  • Dual frequency antenna
