What is ground-penetrating radar (gpr)?
Ground-Penetrating Radar transmits radio pulses into concrete or soil and images the reflections, revealing buried pipes, rebar, conduit, voids and zones of saturation. It is invaluable for planning a safe excavation — locating utilities so they aren't struck, and confirming the wash-out a leak creates around a line.
How it works
- 1The GPR antenna is passed over the surface in a grid.
- 2Reflections map the depth and path of buried features.
- 3Voids and saturated soil produce distinct signatures.
- 4We mark utilities and the suspected leak zone.
Advantages
Images both metallic and non-metallic pipes
Estimates depth before digging
Reveals voids and wash-out
Protects against striking utilities
Where we use it
GPR — FAQs
Can GPR find plastic pipes?
Yes — unlike electromagnetic locating, GPR images non-metallic pipes and voids as well as metal services.
Does GPR find the leak itself?
It maps the pipe, depth and any surrounding wash-out; we pair it with acoustics, which find the leak's sound, for a complete picture.
