Port Coquitlam ground conditions & what they mean for GPR
Local geology: Port Coquitlam sits on Pitt River floodplain silts with till toward the north side. Floodplain silts limit deep imaging south of the rail corridor; northern till scans conventionally. Shallow residential services image well throughout.
Local building stock: Postwar bungalows mid-renewal, distribution warehouses on the floodplain, and a compact older downtown with mixed-age services.

Port Coquitlam questions, answered
We already called BC One Call. Why scan privately?
One Call marks public utilities to the property line and only those registered. Private services — irrigation, gas to outbuildings, landscape lighting, old septic, abandoned lines — are invisible to it. Most strikes happen on exactly those, and liability lands on whoever dug.
What do you find most often that records miss?
Abandoned-in-place services, owner-installed plastic gas and water runs, buried oil tanks in pre-1965 neighbourhoods, and duct banks that left the drawings decades ago. Every one is a strike that didn't happen.
How close to your marks can the machine dig?
Standard practice: mechanical excavation to within 60 cm of a mark, hand exposure from there. Our depth flags tell the operator when targets enter the cut profile.
Can you scan the morning of the dig?
Yes — same-day scans within business hours are routine. Marks go down, photos are taken, the report follows by email, and the excavation proceeds the same morning where scheduling allows.
How deep can GPR scan in Port Coquitlam?
Port Coquitlam sits on Pitt River floodplain silts with till toward the north side. Floodplain silts limit deep imaging south of the rail corridor; northern till scans conventionally. Shallow residential services image well throughout. 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 Port Coquitlam, or dispatch from elsewhere?
Port Coquitlam 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).
