What is GPR?

Ground penetrating radar (GPR) is an advanced, non-invasive sub-surface imaging technique that typically uses short pulses of electromagnetic energy to ‘see’ into the ground.  GPR is very good at determining the shape, size, extent and depth of a buried object.  It can be used to find pipes, foundations, voids, trenches, geological layers, reinforcing bars, etc.  It works best in dry ground environments but can also work well in wet, saturated materials.  It does not work very well in saline conditions and through dense clays.

GPR is used by a wide range of people including:

  • Civil Engineers & NDT Archaeologists
  • Geologists
  • Geotechnical Engineers
  • Glaciologists
  • Forensic Investigators
  • Environmental Scientists
  • Hydrologists

In fact, anyone who needs to investigate buried features.  It is particularly popular for utility detection and roadway evaluation.
