Buried Pipe Mapping in Slabs & Ground Across BC
Trace the route and depth of buried pipes before you dig or cut
About This Service
Knowing exactly where buried pipes run — and how deep — is the foundation of any safe excavation or slab repair. GPR traces the path of water mains, gas branches, drainage lines and conduit through soil and concrete with no need to trench exploratory holes. Combined with electromagnetic locating for metal lines, we produce a complete subsurface pipe map that keeps your repair targeted and your buried services intact.
How GPR Works for This Application
- 1
We identify the pipe material: metallic lines are traced with EM; all lines are confirmed with GPR.
- 2
GPR antenna sweeps the route in a grid and perpendicular to the suspected line direction.
- 3
Pipe reflections are identified by their consistent depth profile along the route.
- 4
We mark the line on the surface at regular intervals and note depth.
- 5
A plan or sketch records the route, depth changes and crossing utilities.
Common Use Cases
What You Receive
- Surface-marked pipe route at regular intervals
- Depth estimates along the route
- Combined EM and GPR locate plan
- Written report with route map
- Advisory for safe dig or cut strategy

Frequently asked questions
How accurate is GPR for pipe depth?
Depth accuracy is typically ±10–15% depending on the dielectric properties of the material above the pipe. We state confidence levels in the report.
Can you find radiant heating tubing in a slab?
Yes — PEX and polyethylene radiant tubing shows in GPR data. Running the heating system first (so tubing is warm) allows thermal imaging to confirm the loop layout as well.
What if the pipe route is unknown?
We begin from the known access point (meter, valve or cleanout) and trace outward in both directions, expanding the search area systematically until the route is established.
