Nanaimo ground conditions & what they mean for GPR

Local geology: Nanaimo sits on till and sandstone benches — with documented historic coal workings beneath parts of the city. Standard till performance at surface, but Nanaimo's defining subsurface feature is its coal-mine legacy: old workings and shafts underlie several neighbourhoods, making void detection a local specialty.

Local building stock: Harbour-city mix of heritage districts, mid-century suburbs, and rapid hospital-area densification.

Common pipe tracing & mapping work in Nanaimo

  • Void scans over historic coal workings
  • Pre-development due diligence
  • Service leak tracing in mid-century suburbs
  • Pre-renovation as-builts
  • Strata infrastructure records
  • Facility management documentation

How the Nanaimo site visit works

  1. 1

    Scope the corridor

    We define the survey area from your renovation, repair, or documentation need — a single run or a whole property.

  2. 2

    Trace with GPR + EM

    Both technologies sweep the corridor; everything found is flagged on the surface in real time.

  3. 3

    Depth profile

    Each line gets depth estimates at intervals, because 'where' without 'how deep' still gets utilities hit.

  4. 4

    Deliver the map

    Annotated plan-view PDF standard; CAD (DWG/DXF) for design teams and permanent facility records.

Nanaimo questions, answered

We have no drawings at all for a 1970s building. Can you still map it?

Yes — that is the typical job, not the exception. GPR + EM reconstruct the actual routing of water, drainage, electrical, and gas without any prior records. The map we deliver becomes the building's first reliable as-built.

How is this different from utility locating?

Locating answers 'is it safe to dig here next week.' Mapping answers 'what do we own and where does it run' — a permanent record for renovations, sales, depreciation reports, and future emergencies. Same technologies, deeper deliverable.

Can you map radiant heating loops in floors?

Yes — hydronic loops image clearly with the 1.6 GHz antenna. Essential before anchoring anything to a heated slab, and valuable documentation when selling a home with radiant heat.

Do strata depreciation reports use this?

Increasingly, yes. Knowing actual pipe routing and material lets the depreciation provider model renewal costs on facts instead of assumptions — and our mapping reports attach directly as appendices.

How deep can GPR scan in Nanaimo?

Nanaimo sits on till and sandstone benches — with documented historic coal workings beneath parts of the city. Standard till performance at surface, but Nanaimo's defining subsurface feature is its coal-mine legacy: old workings and shafts underlie several neighbourhoods, making void detection a local specialty. 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 Nanaimo, or dispatch from elsewhere?

Nanaimo is part of our standing Vancouver Island 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 Nanaimo. 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. Call 604-239-9934 and we will give you a tight estimate in five minutes.
