Delta ground conditions & what they mean for GPR
Local geology: Delta sits on Fraser delta silts in Ladner/Tsawwassen lowlands, till ridge through North Delta. Lowland silts behave like Richmond — shallow water table, limited depth; the North Delta till ridge scans conventionally. Farm drainage networks add target density.
Local building stock: Agricultural parcels with decades of private piping, Tsawwassen slab-on-grade subdivisions, and port-industrial lands.

How the Delta site visit works
- 1
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.
- 4
Imagery report
Annotated scans, depth tables, and marked photos delivered for the project record.
Delta 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 Delta?
Delta sits on Fraser delta silts in Ladner/Tsawwassen lowlands, till ridge through North Delta. Lowland silts behave like Richmond — shallow water table, limited depth; the North Delta till ridge scans conventionally. Farm drainage networks add target density. 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 Delta, or dispatch from elsewhere?
Delta is part of our standing Metro Vancouver 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 concrete scanning cost in Delta?
Pricing matches our province-wide structure — no regional premium for Delta. 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.
