Non-Destructive Digging

Potholing & Service Location

Precisely expose underground pipes, cables, and conduits without risk of damage. Our hydro vacuum method is the safest way to verify service depth and alignment before excavation begins.

How It Works

Our Potholing Process

Every pothole follows a structured, safety-first process.

01

Locate & Mark

Review Dial Before You Dig (DBYD) plans and mark the target area. Confirm known service depths and alignments with the site supervisor.

02

SWMS & Induction

Complete safe work method statements and attend site induction before any work begins. All crew hold current certifications.

03

Controlled Excavation

High-pressure water loosens soil in controlled bursts around the target zone. Vacuum simultaneously removes spoil into the debris tank — no hand digging near live services.

04

Service Exposure & Documentation

Buried services are carefully exposed and visually confirmed. We photograph every located service and provide documentation on request.

05

Backfill & Reinstatement

Once inspection or connection is complete, the pothole is backfilled with clean material and the surface reinstated to site requirements.
