Non-Destructive Digging

Hydro Excavation

High-volume excavation using pressurised water and industrial vacuum — the safest method for bulk earthworks around live gas, electrical, water, and telecommunications infrastructure.

How It Works

Our Hydro Excavation Process

Every excavation follows a structured, safety-first process.

01

Project Scoping

Review drawings, DBYD data, and site conditions. Confirm truck access, water supply, and spoil disposal requirements.

02

Mobilisation

Deploy the appropriate unit to site. Our mid-range workhorse handles most jobs; the compact unit accesses tight spaces.

03

Hydro Excavation

High-pressure water breaks up the soil while the industrial vacuum simultaneously extracts material into the debris tank — no mechanical contact with live services.

04

Spoil Management

Debris is transported and disposed of at a licensed facility. Disposal manifests provided on every job.

05

Quality Check

Excavation is inspected against scope and specification. Any remediation or further digging is completed before demobilisation.

06

Site Reinstatement

Area is cleaned, backfilled if required, and reinstated to the agreed standard. Site left clean and compliant.
