Underground Leak Detection in Sidney, BC

Sidney ground is predominantly marine sands and gravels on the Saanich Peninsula lowland, and that cuts both ways: it governs whether escaping water surfaces or vanishes, and how far leak noise carries to our sensors. Dry peninsula sands are excellent — consistent 3 m penetration makes Sidney one of the Island's cleanest scan environments. Method selection here starts from the dirt — acoustic spacing, GPR antenna choice, and when aerial thermal screening earns its place on long runs.

Compact seaside town of postwar bungalows and newer condos, with airport-industrial lands adjacent. 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 Sidney meter moves and nothing shows above ground.

Province-wide pricing — no regional premium for Sidney 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.
