Ground Penetrating Radar Scanning
Non-destructive subsurface scanning that finds the non-metallic underground services and hidden ground anomalies electromagnetic locators cannot see.
Ground Penetrating Radar (GPR) is a non-destructive geophysical method that transmits radar pulses into the ground and records the reflections from buried objects, voids, and material interfaces. Because GPR does not rely on a conductive signal, it is the only reliable way to find non-metallic underground targets such as PVC water mains, HDPE gas lines, and fibre optic conduits in soil.
Technicians select the antenna and frequency to suit the site, with lower-frequency antennas reaching deeper utility, void, and geological targets. Typical underground applications include void and sinkhole mapping, underground storage tank location, pavement and subgrade analysis, and the detection of unknown or abandoned services that no longer appear on any plan.

- Tank and UST (underground storage tank) location
- Grave and archaeological survey
- Unknown & Abandoned Services (services that were left in the ground that may still be live or contain hazardous material)
- Void and sinkhole detection
- Forensic investigations
- Pavement and subgrade analysis

Safety Warning
GPR catches what electromagnetic locators cannot. Plastic gas mains, PVC water lines, and fibre optic conduits carry no traceable signal and without GPR they are effectively invisible. A strike on a live HDPE gas main can be catastrophic.
