Cable & Sheath Fault Locating in New Westminster, BC

EM line tracing is largely soil-independent — it follows the signal on the conductor regardless of what's around it — but GPR, the half that finds non-conductive plastic and clay lines, is very soil-sensitive. New Westminster sits on predominantly till bluffs over Fraser riverfront fill. Hilltop till scans well; the riverfront flats are historic fill with brick, timber, and rail-era debris that demands experienced interpretation. So in New Westminster we lean on EM for the metal and tracer-wired lines and set realistic GPR expectations for the plastic — which is exactly why running both methods matters here.

The local mix follows the building stock: BC's oldest city — Victorian-era Queens Park homes, brick-age downtown services, and riverfront industrial conversions. Underneath that, the everyday New Westminster locate is private water and irrigation services, power to outbuildings and gates, gas to outdoor features, and the plastic mains that need GPR or sonde tracing — the private-side utilities no public locate covers.

Yes. BC One Call marks member utilities' public lines to the property line across New Westminster and all of BC — it does not locate the private services beyond it, which is where most strikes happen. The EM + GPR clearance survey covers those private lines. Use both: BC One Call for the public locates, a private dual-method locate for everything on your side.

Province-wide pricing — no regional premium for New Westminster or anywhere in the Metro Vancouver. A focused clearance (a dig area, a fence line) starts in the low-to-mid hundreds; full-site mapping and SUE-grade work are quoted by scope. The free phone consult (604-239-9934) gives a firm number in about five minutes. Mon–Sat, 8am–6pm PT.

Yes — that's the entire point of fault locating. Continuity testing tells you a fault exists; EM fault-finding tells you where. By tracing the applied signal and watching how it fades at a break or diverts to ground at a sheath fault, the location narrows to a small marked area. The repair crew digs one hole at the fault instead of trenching the whole run hunting for it.

A sheath (or insulation) fault is where a cable's protective covering is damaged and current leaks to the surrounding ground rather than staying on the conductor. It's tricky because the line may still partly work, so simple continuity checks miss it — it takes ground-return fault-finding techniques that follow where the signal escapes to earth. Those are exactly the methods this service uses.
