Parking Garage Slab Scanning in Duncan, BC

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.

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.

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.

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.

Duncan sits on Cowichan Valley alluvium — sands and silts with seasonal saturation. Summer scans reach well into the alluvium; winter saturation shortens range. Farm and First Nations lands carry generations of undocumented lines. 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.

Duncan 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).
