Underground Water Leak Detection in Victoria, BC
GPR + acoustic correlation locates buried water service line and main leaks before any excavation — typically narrowing the dig to a 1-metre window. Serving Victoria and the Vancouver Island region with certified technicians, non-invasive methods, and insurance-ready documentation — since 1999.

Victoria ground conditions & what they mean for GPR
Local geology: Victoria sits on Victoria clay over bedrock, with rock outcropping through much of the core. The famous blue clay attenuates GPR quickly when wet — winter surveys run shallower than summer ones. Rock outcrops end penetration but also force utilities into predictable corridors.
Local building stock: Canada's oldest West Coast housing — pre-1940 homes with oil-tank histories, brick-era downtown services, and heritage strata conversions.

How the Victoria site visit works
- 1
Confirm flow
Meter isolation confirms water is moving with all fixtures off — establishing an active underground leak before any survey cost.
- 2
GPR pipe trace
The buried line is traced and depth-profiled with 200–400 MHz GPR so the acoustic work targets the actual alignment, not a guess.
- 3
Acoustic correlation
Sensors at two access points triangulate the leak sound along the traced line — typically within 30 cm.
- 4
Mark + report
Dig window marked on the surface; written report with GPR profile, correlation output, and depth estimate delivered within 24 hours.
Victoria questions, answered
Does GPR find the water leak itself?
GPR locates and depth-profiles the buried pipe and can image disturbed, water-saturated soil around a failure. The leak point itself is confirmed by acoustic correlation along the GPR-traced alignment — the two technologies together produce a dig window the width of a shovel, not a trench.
How deep can you trace a residential service line?
Most BC residential service lines sit 0.6–1.2 m deep — comfortably within 400 MHz GPR range in typical till and sand soils. Wet clay or saline fill reduces range; in those conditions we lean more heavily on acoustic methods and EM tracing.
Do you need to shut off my water?
Briefly, during the meter-isolation step that confirms the leak. The acoustic correlation itself works on a pressurised, flowing line — that is what makes the leak audible.
What does this cost compared to exploratory digging?
A located leak typically needs a 1 m × 1 m excavation. Un-located leaks routinely require trenching the full line at 10–30× the cost. Detection is usually $450–$1,200 and pays for itself in the first metre of digging avoided.
How deep can GPR scan in Victoria?
Victoria sits on Victoria clay over bedrock, with rock outcropping through much of the core. The famous blue clay attenuates GPR quickly when wet — winter surveys run shallower than summer ones. Rock outcrops end penetration but also force utilities into predictable corridors. 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 Victoria, or dispatch from elsewhere?
Victoria is part of our standing Vancouver Island 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).
