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

Surrey ground conditions & what they mean for GPR
Local geology: Surrey sits on till uplands across Whalley and Fleetwood, Serpentine/Nicomekl floodplain silts through the lowlands. Upland till scans 2–3 m reliably; the Serpentine and Nicomekl floodplains run wet and silty, so deep targets there lean on EM pairing and tighter grids.
Local building stock: BC's fastest-growing city — City Centre highrise slabs, vast 1980s–2000s subdivisions, and farm parcels with undocumented private services.
Common sewer leak detection work in Surrey
- Pre-construction locates on infill developments
- Private utility mapping on agricultural parcels
- Underground service leak tracing in 1980s subdivisions
- Slab scanning across City Centre tower construction
- Sub-slab sewer failures
- Yard lateral leaks
- Pre-sinkhole void detection
How the Surrey 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.
Surrey 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 Surrey?
Surrey sits on till uplands across Whalley and Fleetwood, Serpentine/Nicomekl floodplain silts through the lowlands. Upland till scans 2–3 m reliably; the Serpentine and Nicomekl floodplains run wet and silty, so deep targets there lean on EM pairing and tighter grids. 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 Surrey, or dispatch from elsewhere?
Surrey 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).
What does sewer leak detection cost in Surrey?
Pricing matches our province-wide structure — no regional premium for Surrey. Most residential-scale work falls in the $350–$1,200 range depending on scope; commercial and multi-site projects are quoted after a free phone consult. Call 604-239-9934 and we will give you a tight estimate in five minutes.
