Sewer Leak Detection in North Vancouver, BC
GPR finds the voids and washouts that leaking sewers carve around themselves, while CCTV confirms the failure from inside the pipe. Serving North Vancouver and the Metro Vancouver region with certified technicians, non-invasive methods, and insurance-ready documentation — since 1999.

North Vancouver ground conditions & what they mean for GPR
Local geology: North Vancouver sits on coarse till and colluvium over shallow bedrock on the mountain slopes. Coarse till scans cleanly until bedrock ends penetration — often within 1–2 m on upper slopes. Services squeezed into that shallow band image sharply.
Local building stock: Steep-lot homes with long private service runs, creek-adjacent properties, and mid-rise growth around Lonsdale.
Common sewer leak detection work in North Vancouver
- Service line leak tracing on steep lots
- Pre-excavation scans where bedrock forces shallow utilities
- Slab scanning in Lonsdale mid-rises
- Sub-slab sewer failures
- Yard lateral leaks
- Pre-sinkhole void detection
How the North Vancouver site visit works
- 1
GPR void survey
Leaking sewers erode soil around the failure. GPR images these voids and saturated zones from the surface — often before any surface symptom.
- 2
CCTV inspection
A push camera or crawler documents the failure from inside: cracks, offset joints, root intrusion, with PACP defect coding.
- 3
Correlate
The GPR anomaly and the CCTV defect footage are matched by chainage so the surface mark sits exactly over the failure.
- 4
Repair scope
Report recommends point repair, lining, or replacement — with the void extent documented for ground remediation.
North Vancouver questions, answered
Why use GPR when a sewer camera already exists?
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.
Can you find sewer leaks under slabs?
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.
What is PACP coding and why does it matter?
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.
Do leaking sewers affect my water bill?
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.
How deep can GPR scan in North Vancouver?
North Vancouver sits on coarse till and colluvium over shallow bedrock on the mountain slopes. Coarse till scans cleanly until bedrock ends penetration — often within 1–2 m on upper slopes. Services squeezed into that shallow band image sharply. 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.
Do you actually work in North Vancouver, or dispatch from elsewhere?
North Vancouver is part of our standing Metro Vancouver service area — the same certified technicians and equipment that cover the rest of the region. Scheduling is typically within 24–72 hours, with same-day response often possible during business hours (Mon–Sat, 8am–6pm Pacific).
