Electromagnetic (EM) Utility Locating in Richmond, BC

EM excels on anything carrying or capable of carrying a signal — live cables, metallic pipes, tracer-wired plastics — with pinpoint lateral accuracy. It cannot see unwired plastic pipe, concrete duct banks, septic tanks, or voids; that is GPR's territory. A professional locate runs both, every time.

Usually — induction mode energises the line through the soil from the surface, and passive mode picks up signals already on power and telecom cables. Accuracy is best with direct connection, which is why we open access points where they exist.

Typically within ±10% of true depth over a clean single line. Congested corridors with parallel services distort fields, so we flag depth confidence honestly in the report — and recommend hand exposure near critical crossings regardless.

Yes — passive 50/60 Hz and radio-frequency detection finds energised cables without contact. Live circuits are marked in red with depth flags, and we recommend hand digging within 60 cm of any electrical mark, per standard practice.

Only partially. BC 1 Call marks registered public utilities up to your property line — free, and you should always use it. Everything inside the line is private and unmarked: irrigation, gas runs to outbuildings, landscape lighting, old septic, abandoned services. Richmond's stock — slab-on-grade construction nearly everywhere, dyke-protected industrial parks, and extensive irrigation and drainage infrastructure. — is exactly where those private surprises accumulate. Private locating closes that gap before you dig.

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. Where local conditions limit one technology, the survey leans on the others — EM tracing, sonde work, and acoustic methods — so the locate objective is met regardless of soil.
