Powell River ground conditions & what they mean for GPR
Local geology: Powell River sits on coastal till over bedrock with sandy raised-beach terraces. Terrace sands scan beautifully; till-over-rock sections end at bedrock. The historic Townsite's century-old services sit shallow and dense.
Local building stock: National-historic-district Townsite homes (1910s), mill-era infrastructure, and waterfront acreages up the coast.

Define objectives
Coring clearance, structural QA, or full as-built — the objective sets grid density and coverage.
- 2
Grid scan
Orthogonal passes build a complete internal image; suspect areas get tightened grids.
- 3
Interpret on site
Targets identified and marked in real time — crews see results before we leave.

Powell River questions, answered
GPR vs X-ray for concrete — which is better?
GPR needs one side of the slab, no radiation permits, no area evacuation, and scans 10× faster at lower cost. X-ray wins only on sub-centimetre detail for congested embeds when both slab faces are accessible. For 95% of BC scanning work, GPR is the right tool.
Can GPR find voids inside the concrete itself?
Yes — honeycombing and consolidation voids reflect distinctly. Common finds in older pours and patch repairs; each gets boundary-marked for the engineer.
How fast can you clear core locations?
Single locations clear in 15–30 minutes including marking. A typical tenant-improvement scope of 10–20 penetrations clears in a half day, same-visit drilling included.
Is the equipment safe to use in occupied buildings?
Completely — GPR emits less RF energy than a phone. No evacuation, no permits, no disruption to tenants or hospital/lab equipment.
How deep can GPR scan in Powell River?
Powell River sits on coastal till over bedrock with sandy raised-beach terraces. Terrace sands scan beautifully; till-over-rock sections end at bedrock. The historic Townsite's century-old services sit shallow and dense. 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.
