Fort St. John ground conditions & what they mean for GPR
Local geology: Fort St. John sits on Peace plateau clays with deep seasonal frost. Clay attenuation plus metre-plus frost defines northern survey planning — summer windows give the best returns, and frost-depth services sit deeper than anywhere else in BC.
Local building stock: Energy-sector service city — industrial yards, work camps, and newer subdivisions built to northern frost specs.

Fort St. John 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 Fort St. John?
Fort St. John sits on Peace plateau clays with deep seasonal frost. Clay attenuation plus metre-plus frost defines northern survey planning — summer windows give the best returns, and frost-depth services sit deeper than anywhere else in BC. 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.
