Courtenay ground conditions & what they mean for GPR
Local geology: Courtenay sits on Comox Valley alluvium and glacial outwash. Outwash terraces scan deep and clean; river-flat parcels run seasonally wet. Agricultural legacy piping is common across the valley floor.
Local building stock: Valley farm parcels, growing retirement subdivisions, and a compact riverside downtown.

How the Courtenay site visit works
- 1
Scope the corridor
We define the survey area from your renovation, repair, or documentation need — a single run or a whole property.
- 2
Trace with GPR + EM
Both technologies sweep the corridor; everything found is flagged on the surface in real time.
- 3
Depth profile
Each line gets depth estimates at intervals, because 'where' without 'how deep' still gets utilities hit.
- 4
Deliver the map
Annotated plan-view PDF standard; CAD (DWG/DXF) for design teams and permanent facility records.
Courtenay questions, answered
We have no drawings at all for a 1970s building. Can you still map it?
Yes — that is the typical job, not the exception. GPR + EM reconstruct the actual routing of water, drainage, electrical, and gas without any prior records. The map we deliver becomes the building's first reliable as-built.
How is this different from utility locating?
Locating answers 'is it safe to dig here next week.' Mapping answers 'what do we own and where does it run' — a permanent record for renovations, sales, depreciation reports, and future emergencies. Same technologies, deeper deliverable.
Can you map radiant heating loops in floors?
Yes — hydronic loops image clearly with the 1.6 GHz antenna. Essential before anchoring anything to a heated slab, and valuable documentation when selling a home with radiant heat.
Do strata depreciation reports use this?
Increasingly, yes. Knowing actual pipe routing and material lets the depreciation provider model renewal costs on facts instead of assumptions — and our mapping reports attach directly as appendices.
How deep can GPR scan in Courtenay?
Courtenay sits on Comox Valley alluvium and glacial outwash. Outwash terraces scan deep and clean; river-flat parcels run seasonally wet. Agricultural legacy piping is common across the valley floor. 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 Courtenay, or dispatch from elsewhere?
Courtenay is part of our standing Vancouver Island 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).
