Core Drilling Safety Scanning in Victoria, BC
Every core hole cleared before the bit touches concrete — rebar, PT cables, conduits, and in-slab pipes mapped at each penetration point. Serving Victoria and the Vancouver Island region with certified technicians, non-invasive methods, and insurance-ready documentation — since 1999.

Victoria ground conditions & what they mean for GPR
Local geology: Victoria sits on Victoria clay over bedrock, with rock outcropping through much of the core. The famous blue clay attenuates GPR quickly when wet — winter surveys run shallower than summer ones. Rock outcrops end penetration but also force utilities into predictable corridors.
Local building stock: Canada's oldest West Coast housing — pre-1940 homes with oil-tank histories, brick-era downtown services, and heritage strata conversions.

How the Victoria site visit works
- 1
Scan each core point
Two-direction local scan at every planned penetration; embedded targets identified by type and depth.
- 2
Clear or offset
Clean points are cleared; obstructed points get the nearest safe offset marked — keeping the trade's layout intent.
- 3
Mark + photograph
Targets and safe windows painted and photographed; the record drives the report.
- 4
Stand by if needed
For dense embed zones we stay through drilling — re-scanning offsets in real time as cores advance.
Victoria questions, answered
The drilling sub says they'll 'go slow and feel for steel'. Good enough?
Feel finds rebar after the bit is already in it — which still costs a bit and a patch, and does nothing for the PT cable or live conduit one centimetre deeper. Scanning costs a fraction of one damaged cable repair and removes the gamble entirely.
Can you clear cores through suspended slabs with services below?
Yes — and we pair the GPR scan with a look at the underside where accessible, because sprinkler mains and cable trays hung beneath the slab are the other half of core-strike risk.
How many cores can you clear in a day?
Routine TI scopes run 20–40 locations per day including marking. Congested mechanical rooms run slower because every point carries embeds — those are exactly the points worth the time.
Do engineers accept your scan documentation?
Yes — structural engineers regularly condition coring permission on our scan report. Marked photos plus depth tables per location is the format they expect.
How deep can GPR scan in Victoria?
Victoria sits on Victoria clay over bedrock, with rock outcropping through much of the core. The famous blue clay attenuates GPR quickly when wet — winter surveys run shallower than summer ones. Rock outcrops end penetration but also force utilities into predictable corridors. 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 Victoria, or dispatch from elsewhere?
Victoria 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).
