Vancouver ground conditions & what they mean for GPR
Local geology: Vancouver sits on glacial till uplands with deltaic sands toward False Creek and Fraser flats. Till and sand image well — 400 MHz reaches 2–3 m across most of the city; signal shortens in fill zones around False Creek and the port lands.
Local building stock: Pre-1965 oil-tank-era homes on the west side, post-tensioned towers downtown, and some of BC's oldest buried services in Strathcona and Mount Pleasant.

How the Vancouver site visit works
- 1
Records review
Available drawings and BC One Call public locates are reviewed first — then treated as hints, not truth.
- 2
EM sweep
Energised and conductive utilities are traced with electromagnetic locating — fast and precise for anything carrying signal.
- 3
GPR grid
GPR finds what EM cannot: plastic water and gas lines, concrete duct banks, septic components, old abandoned services.

Mark + map
Paint and flags on the ground for the crew; optional CAD plan for the permit set or engineering record.
Vancouver questions, answered
Doesn't BC One Call already do this for free?
BC One Call locates public utilities up to your property line. Everything past the line — the gas run to the garage heater, irrigation mains, the old abandoned service — is private and unmarked. Striking it is the digging party's liability, which is why private locating exists.
How accurate are the surface marks?
Within 5–10 cm horizontally for most targets at typical utility depths, with depth estimates ±10%. We mark conservatively and recommend hand-digging the last 30 cm near any mark — the same rule professional excavators follow.
Can you locate utilities under driveways and slabs?
Yes — GPR scans through asphalt and concrete. Duct banks, conduits, and pipes under paved surfaces image well, which matters because that is exactly where most accidental strikes happen.
Do I get documentation for WorkSafe BC compliance?
Yes. The written locate report — marks photographed, targets listed with depths, methodology stated — supports your damage-prevention duty of care under WorkSafe BC excavation requirements.
How deep can GPR scan in Vancouver?
Vancouver sits on glacial till uplands with deltaic sands toward False Creek and Fraser flats. Till and sand image well — 400 MHz reaches 2–3 m across most of the city; signal shortens in fill zones around False Creek and the port lands. 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 Vancouver, or dispatch from elsewhere?
Vancouver 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 underground utility locating cost in Vancouver?
Pricing matches our province-wide structure — no regional premium for Vancouver. 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.
