Parking Garage Slab Scanning in Richmond, 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.

Richmond sits on Fraser delta silts and peat with a water table often within a metre of grade. Richmond is BC's most depth-limited GPR environment — saturated silts attenuate signal fast. Shallow targets still image well, and we compensate with EM, acoustic, and tracer methods for deeper work. 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.

Richmond 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).

Pricing matches our province-wide structure — no regional premium for Richmond. 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.
