Sewer Leak Detection in Squamish, BC

The camera sees the pipe's inside; GPR sees what the leak has done to the ground around it. A hairline crack can hide a washout void several times the pipe diameter — the thing that eventually becomes a sinkhole. Scoping the repair without the void picture routinely under-scopes the job.

Yes — under-slab sanitary failures are a classic GPR call. The void and moisture halo image clearly through 100–200 mm slabs with the 1.6 GHz antenna, and CCTV confirms from the cleanout.

PACP (Pipeline Assessment Certification Program) is the NASSCO standard for coding pipe defects. Coded reports let engineers, municipalities, and insurers compare condition objectively — and they hold up in disputes.

Usually no — sewers are gravity drains, not pressurised supply. The cost shows up instead as ground settlement, odours, pest attraction, and eventually structural undermining. That is why void detection matters more than flow measurement on sanitary leaks.

Squamish sits on glaciofluvial outwash sands and gravels on the Squamish River delta. Outwash sands give excellent penetration; delta-front and estuary parcels run wetter. One of the cleaner GPR environments on the coast. We select antenna frequency to match — and where local ground limits radar depth, we pair GPR with electromagnetic locating, acoustic methods, or tracer gas so the survey objective is met regardless of soil conditions.
