Method
Ground-Penetrating Radar (GPR)
Seeing into concrete and soil before cutting or digging.
GPR sends radio pulses into material and reads reflections to map rebar, conduits, hidden services and voids, so cutting, coring and excavation avoid what is inside.
How it works
- Grid scans over the area of interest
- Targets marked with depth estimates
- Caution zones noted for post-tension or dense services
Limits, stated plainly
- Metal ducts and wet material limit depth
- Results depend on material conditions
- Findings are marked, not excavated

Quick answers
Is Ground-Penetrating Radar (GPR) invasive?
No. The method works from surfaces and accessible points; if a small access point is needed to confirm a finding, it is discussed before anything is opened.
Can Ground-Penetrating Radar (GPR) be used on its own?
Ground-Penetrating Radar (GPR) is strongest when paired with a confirming method. Findings are only reported once verified, which is why single-method clues are labelled as such.
