Underground Leak Detection in Duncan, BC

Duncan ground is predominantly Cowichan Valley alluvium — sands and silts with seasonal saturation, and that cuts both ways: it governs whether escaping water surfaces or vanishes, and how far leak noise carries to our sensors. Summer scans reach well into the alluvium; winter saturation shortens range. Farm and First Nations lands carry generations of undocumented lines. Method selection here starts from the dirt — acoustic spacing, GPR antenna choice, and when aerial thermal screening earns its place on long runs.

Compact heritage downtown, surrounding farm parcels, and valley acreages with legacy water systems. Underneath that stock: service laterals from each building era, irrigation mains in the landscaped areas, and site services on the larger parcels — the usual suspects when a Duncan meter moves and nothing shows above ground.

Province-wide pricing — no regional premium for Duncan or anywhere in the Vancouver Island. Single investigations start in the low-to-mid hundreds; larger properties and multi-system files are quoted by scope. The free phone consult (604-239-9934) produces a firm number in about five minutes. Mon–Sat, 8am–6pm PT.

Three physical signatures reach the surface: sound (pressurised escape resonates along pipe and soil — correlators and ground mics triangulate it), ground change (GPR maps saturation and washed-out bedding), and heat behaviour (saturated soil lags dry soil's daily swing — readable thermally, including from the air on long runs). Stacked, they converge on a dig point; any one alone can be fooled.

Because soil routes it away first — along trench bedding, into drains and gravel seams, downward through free-draining ground. In much of BC, a service line can pass thousands of litres a day for months with the lawn above bone-dry. The meter notices; the surface lies. That asymmetry is the entire case for instrument-based location.
