Pipe Leak Detection in Surrey, BC
Any pipe, any material — metal, PVC, PEX, asbestos-cement. GPR sees what EM locators can't, and pairs with acoustic and tracer gas for the confirmation. 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 pipe 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
- Plastic (PVC/PEX) lines EM can't trace
- Mixed-material systems
- Fire lines
How the Surrey site visit works
- 1
Map the run
GPR traces the pipe regardless of material — the critical advantage over EM locators, which need conductive pipe or tracer wire.
- 2
Choose the confirmer
Pressurised metallic lines get acoustic correlation. Quiet, low-pressure, or plastic lines get hydrogen tracer gas — the sniffer finds gas escaping at the failure.
- 3
Cross-confirm
Two independent technologies agreeing at one point is the standard before we mark any dig.

Report
Plan-view map with depths, the marked leak point, and the recommended repair access — delivered within 24 hours.
Surrey questions, answered
Can you find leaks in PVC and PEX pipes?
Yes — this is exactly where GPR earns its place. Electromagnetic locators cannot trace non-conductive pipe, but GPR images plastic lines by density contrast. Once traced, tracer gas confirms the leak point on quiet plastic lines that acoustic methods struggle with.
What about asbestos-cement (AC) water mains?
Common in BC systems built 1950s–1970s. GPR traces AC mains well, and acoustic correlation works on the pressurised line. We flag AC pipe in the report because repairs require hazmat handling.
Do you locate fire suppression line leaks?
Yes — buried fire lines between the street and the sprinkler room are a frequent commercial call. They hold pressure, which makes acoustic correlation effective once GPR establishes the alignment.
What if the pipe location is completely unknown?
That is the normal starting point. GPR grid-scans the corridor, finds the pipe, then the leak workflow proceeds. No drawings needed — we generate the as-built as part of the job.
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 pipe 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.
