Post-Tension Cable Mapping in Salmon Arm, BC

A tensioned strand carries roughly 15–20 tonnes of force. Cut it and the strand can rupture through the slab edge or eject anchor hardware at lethal speed — and the slab loses design capacity in that bay. Repairs run tens of thousands. The scan that prevents it takes under an hour per zone.

PT became common in BC towers and parkades from the early 1970s onward. Most highrise residential and commercial floors poured since then are candidates — assume PT until a scan or structural drawing proves otherwise.

Yes — PT cables run in draped profiles at distinctive spacings and depths, while rebar sits in regular flat mats. An experienced analyst separates them reliably, and we mark them differently on the slab.

We provide a scan report with marked imagery and safe-window documentation. Contractors and building managers use it as the diligence record for permits and insurance. Final drilling authority always rests with the structural engineer where one is engaged.

Salmon Arm sits on lakeshore silts with till benches above. Bench till scans conventionally; lakeshore silts run wetter. Agricultural parcels around the bay carry extensive private piping. 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.
