About

A local operator built for professional, reliable underground work.

Dial-A-Trench is an owner-operated trenching and excavation business based at St Agnes, serving builders, contractors and utilities right across metropolitan Adelaide.

Our approach

You deal with the person on the machine.

There’s no layer of management between you and the work. When you engage Dial-A-Trench, you’re briefing the operator directly — which means clear communication, careful work and one point of accountability from the first call to the final reinstatement.

We’ve built the business around the jobs others find awkward: tight side-access, confined courtyards, work around live services, and sites where a clean, well-documented result matters. Tight access excavation is our specialty.

Every job is quoted competitively and carried out to standard — licensed, insured, and backed by diligent use of Dial Before You Dig and on-site cable locating.
