Pre-Excavation Surveys

Pre-excavation GPR surveys are insurance against very expensive mistakes. We mobilize for trenching, micro-piling, micro-tunneling, foundation work, anchor drilling and any subsurface intervention where a strike on a live utility or anchor structure would create a project crisis. The work is fast, the cost is small relative to the consequences, and the deliverable is a confidence-grade marked-up site plan that crews can work from with eyes open.

Why Pipe GPR for pre-excavation surveys

Pipe GPR is a sub-division of Leak.ca, the Greater Vancouver leak detection company trusted since 1999. Every site visit is delivered by certified technicians using calibrated equipment, with documented findings formatted for insurance, engineering and procurement use.

We don't sell remediation. Our role is independent detection and assessment — the data you and your professional team work from.

Pairs well with

Clients booking pre-excavation surveys often combine it with Private Utility Locating or Concrete Scanning — particularly when the underlying issue spans multiple systems or when documentation needs to support a broader investigation.

How to prepare for your visit

1. Document what you're seeing. Photos, dates, sounds, water-bill changes, anything unusual. The more we know in advance, the faster we can locate.
2. Clear access to the suspected area. Move furniture, stored items, and rugs. Non-invasive methods still need clear sightlines.
3. Have system history ready. Recent plumbing work, prior leaks, renovations, age of property, prior insurance claims.
4. Confirm the email for your report. Photo-linked report delivered within 48 hours (often same-day for residential).
