Parking Garage Slab Scanning in Terrace, BC
Parkade decks fail from the inside — chloride-corroded rebar, delamination, membrane leaks. GPR maps the deterioration before the spalling starts. Serving Terrace and the Northwest BC region with certified technicians, non-invasive methods, and insurance-ready documentation — since 1999.

Terrace ground conditions & what they mean for GPR
Local geology: Terrace sits on Skeena valley sands and gravels. Free-draining river terraces scan deep; high rainfall keeps low-lying parcels wet. Industrial-project growth drives most locate demand.
Local building stock: Skeena service hub — industrial staging sites, postwar neighbourhoods, and rural acreages along the highway corridors.

How the Terrace site visit works
- 1
Grid the deck
Drive lanes and stalls scanned in a continuous grid; suspended decks and slab-on-grade handled with appropriate antennas.
- 2
Map deterioration
Chloride-saturated and delaminating zones attenuate the GPR signal distinctively — those zones get boundary-mapped.
- 3
Correlate leaks
Membrane failures above show as moisture anomalies; we tie deck condition to the leak sources driving it.
- 4
Engineer-ready report
Condition plan with quantified deterioration areas — the basis for repair budgeting and depreciation planning.
Terrace questions, answered
Our parkade ceiling shows white stains and drips. What does GPR add?
Efflorescence tells you water is moving through the slab; GPR tells you what it has done inside — where rebar corrosion is active, how far delamination extends, and which bays need repair versus monitoring. Repair scoped on stains alone routinely misses half the deteriorated area.
Can you scan while the parkade stays open?
Yes — we work bay-by-bay with simple cone closures, off-peak where stalls are assigned. No resident parking disruption beyond the bay being scanned.
How does this feed a depreciation report?
Quantified deterioration percentages per deck area convert directly into renewal-cost line items. BC depreciation providers accept our condition plans as appendices — it turns a guess about parkade life into a measured input.
Is this the same as chain dragging?
Chain drag finds delamination that already exists by sound; GPR maps both current delamination and the chloride/corrosion zones that predict the next five years of it. Most engineering assessments now want both — we coordinate with the engineer's protocol.
How deep can GPR scan in Terrace?
Terrace sits on Skeena valley sands and gravels. Free-draining river terraces scan deep; high rainfall keeps low-lying parcels wet. Industrial-project growth drives most locate demand. 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 Terrace, or dispatch from elsewhere?
Terrace is part of our standing Northwest BC 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).
