Mission ground conditions & what they mean for GPR

Local geology: Mission sits on steep till and bedrock benches above Fraser floodplain. Hillside till scans well between rock outcrops; the floodplain industrial flats are wetter. Slope properties put services shallow and traceable.

Local building stock: Hillside homes with long gravity-fed service runs, heritage downtown, and floodplain industry.

Common underground utility locating work in Mission

  • Hillside service line leak tracing
  • Industrial flat utility mapping
  • Heritage-area locates

How the Mission site visit works

  1. 1

    Records review

    Available drawings and BC One Call public locates are reviewed first — then treated as hints, not truth.

  2. 2

    EM sweep

    Energised and conductive utilities are traced with electromagnetic locating — fast and precise for anything carrying signal.

  3. 3

    GPR grid

    GPR finds what EM cannot: plastic water and gas lines, concrete duct banks, septic components, old abandoned services.

  4. 4

    Mark + map

    Paint and flags on the ground for the crew; optional CAD plan for the permit set or engineering record.

Mission questions, answered

Doesn't BC One Call already do this for free?

BC One Call locates public utilities up to your property line. Everything past the line — the gas run to the garage heater, irrigation mains, the old abandoned service — is private and unmarked. Striking it is the digging party's liability, which is why private locating exists.

How accurate are the surface marks?

Within 5–10 cm horizontally for most targets at typical utility depths, with depth estimates ±10%. We mark conservatively and recommend hand-digging the last 30 cm near any mark — the same rule professional excavators follow.

Can you locate utilities under driveways and slabs?

Yes — GPR scans through asphalt and concrete. Duct banks, conduits, and pipes under paved surfaces image well, which matters because that is exactly where most accidental strikes happen.

Do I get documentation for WorkSafe BC compliance?

Yes. The written locate report — marks photographed, targets listed with depths, methodology stated — supports your damage-prevention duty of care under WorkSafe BC excavation requirements.

How deep can GPR scan in Mission?

Mission sits on steep till and bedrock benches above Fraser floodplain. Hillside till scans well between rock outcrops; the floodplain industrial flats are wetter. Slope properties put services shallow and traceable. 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.

Do you actually work in Mission, or dispatch from elsewhere?

Mission is part of our standing Fraser Valley 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).
