Concrete Scanning with GPR Across BC
See rebar, post-tension cables, conduit and pipes before cutting, coring or drilling
About This Service
Concrete scanning with Ground-Penetrating Radar (GPR) maps what is hidden inside a slab or wall before any cutting, coring or drilling begins. Unlike X-ray methods, GPR is non-ionising, requires no safety exclusion zone, and produces results in real time on-site. Technicians mark safe cut lines around every embedded hazard — protecting the structure, the repair crew, and costly finishes.
How GPR Works for This Application
- 1
The GPR antenna is moved across the concrete surface in a systematic grid pattern.
- 2
Radio pulses penetrate the slab and reflect off embedded objects — rebar, PT cables, conduit, pipes and voids.
- 3
Each reflection appears as a hyperbola on the scan display; depth and material are interpreted from the signature.
- 4
We mark safe cut-line zones on the surface with chalk or paint, documenting every embedded hazard.
- 5
Results are available immediately on-site, with a scan report produced for your records.

Frequently asked questions
Can GPR find post-tension cables?
Yes. Post-tension cables are a primary hazard in BC's concrete construction and GPR detects them reliably, allowing safe coring around them.
How thick of a slab can you scan?
GPR penetrates 200–400 mm in typical concrete, sufficient for most slabs. Heavier aggregate or highly reinforced sections may reduce depth.
Is this the same as X-ray scanning?
No — GPR uses radio waves, not ionising radiation. There is no safety exclusion zone, and it works in occupied buildings during business hours.
