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.

How the Fort St. John site visit works
- 1
Scan the penetration points
Each drill or anchor location gets a local 1.6 GHz scan in two directions — a 60-second operation per point.
- 2
Distinguish targets
Rebar, conduit, and pipe have distinct reflection signatures and depths; each is identified and labelled.
- 3
Mark clear zones
Safe drilling windows marked directly on the surface; obstructed points get an offset recommendation.
- 4
Same-visit clearance
Crews typically drill immediately after marking — one mobilisation, zero strikes.
Fort St. John questions, answered
How small a conduit can GPR see?
A 12 mm conduit at 50 mm depth resolves clearly with the 1.6 GHz antenna. Resolution decreases with depth — at 300 mm, closely spaced small targets can merge — which is why we scan every penetration point individually rather than extrapolating.
Hitting one conduit doesn't sound expensive. Why scan?
A severed feeder in a live commercial building means an electrician, an outage, possibly a fire-watch, and a schedule slip — routinely $5,000–$50,000 against a scan that costs a few hundred dollars. Hitting a water line in a wall is worse. The economics are not close.
Can you scan walls and ceilings, not just floors?
Yes — the concrete antenna works on any orientation. Wall penetrations for sleeves and ceiling anchors for mechanical hangers are everyday scans.
Do you mark directly on the surface?
Yes — targets in one colour, safe windows in another, photographed for the report. Crews drill against the marks the same visit.
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.
