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.
Common rebar & conduit locating work in Delta
- Farm drainage and irrigation mapping
- Slab-on-grade leak detection in Tsawwassen
- Port-area utility locates
- Anchor bolt layouts
- Electrical conduit avoidance
- Wall penetrations
How the Delta 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.
Delta 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 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).
