GPR Leak Detection in Victoria, BC

Ground is everything in radar. Victoria sits on predominantly 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 pick antennas and set depth expectations to that reality — and pair radar with acoustic confirmation so the conclusion never rests on one instrument.

The local mix follows the building stock: Canada's oldest West Coast housing — pre-1940 homes with oil-tank histories, brick-era downtown services, and heritage strata conversions. In practice that means slab-line location before repairs, washout and void checks where pavement is settling, and buried-line mapping where drawings never existed — the everyday Victoria radar workload.

Province-wide pricing — no regional premium for Victoria 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.

It sees what leaks do to the ground. Radar reflects off contrasts — and water changes ground's dielectric behaviour dramatically. A leak shows as saturation signatures, disturbed or washed-out bedding, and voids where soil migrated into a failing pipe. GPR maps those consequences and the pipe's exact position; acoustic methods then confirm the active escape point. The pairing is the method — neither alone is the whole answer.

GPR earns its place when geometry is unknown or the ground itself is in question: no reliable drawings, suspected voids under slabs, pavement settling near a line, in-slab pipes that must be located before cutting, or rebar that must be cleared before coring into a repair. If the pipe's route is known and the question is purely 'where along it is the leak' — acoustics may be all the job needs, and we'll say so.
