Pipe Locating

1 min read Updated 6 Jul 2026 DrainSpy Brisbane
In short The process of tracing where underground pipes and services run, using sondes, electromagnetic locators and existing plans, before any digging starts.

Locating combines several tools: sonde tracing for non-metallic drains, electromagnetic locating for conductive services, and council or utility plans for context. The goal is a marked-out map of what lies below before an excavator bucket goes anywhere near it.

In Australia, checking Before You Dig Australia (formerly Dial Before You Dig) is a standard first step for any excavation work.

What Is It For?

Prevents damage to services and puts repair excavations exactly where they are needed.

Where You'll Find It

Performed on site before excavation, connection or landscaping work.

Common Problems

  • Unrecorded private drains missing from plans
  • Old materials like earthenware being non-conductive and needing sonde tracing
  • Congested service corridors in older suburbs

How DrainSpy Brisbane Deals With It

A CCTV drain inspection is the standard way to confirm whether this is what's happening in your pipes: the camera shows the condition on screen, a locator pinpoints the exact position and depth, and you get a recorded report before any repair decisions are made.
