Kelowna ground conditions & what they mean for GPR
Local geology: Kelowna sits on dry glaciolacustrine silts and sandy benches — classic Okanagan GPR country. Dry silts and sands give the deepest, cleanest GPR returns in BC — 3–4 m is routine. Irrigation saturation creates local wet anomalies that are themselves diagnostic of leaks.
Local building stock: Lakefront estates with pools and extensive irrigation, orchard and vineyard parcels, and a fast-rising downtown tower skyline.

How the Kelowna site visit works
- 1
Walk the dig plan
Corridor and depth of the planned excavation define the survey footprint, with a safety margin.
- 2
Dual-technology sweep
EM finds live and conductive services; GPR finds plastic lines, tanks, duct banks, and the abandoned surprises.
- 3
Mark everything
Industry-standard colour codes on the ground; depth estimates flagged where targets cross the dig.
- 4
Clearance documentation
Photo-documented marks and a written report — the contractor's damage-prevention record.
Kelowna 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 Kelowna?
Kelowna sits on dry glaciolacustrine silts and sandy benches — classic Okanagan GPR country. Dry silts and sands give the deepest, cleanest GPR returns in BC — 3–4 m is routine. Irrigation saturation creates local wet anomalies that are themselves diagnostic of leaks. 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 Kelowna, or dispatch from elsewhere?
Kelowna is part of our standing Okanagan 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 pre-excavation scanning cost in Kelowna?
Pricing matches our province-wide structure — no regional premium for Kelowna. 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.
