Vacuum excavation
Our non-destructive digging services are ideal for locating underground utilities such as Telstra cables, gas lines, and water mains. With our vacuum truck, we safely expose services without damaging surrounding infrastructure — perfect for plumbing contractors, councils, and civil projects.
Whether it's a planned dig or an emergency call-out, we deliver responsive vacuum excavation across Adelaide and the surrounding regions.
Earthworks and landscaping
We handle everything from pad preparation for new builds to full landscaping packages for residential or commercial developments. Our team is experienced in earth shaping, road prep, and base works, while also offering light landscaping — including retaining walls (up to 1m), paving, and reticulation.
If you're working on a subdivision or new home site, we provide accurate levels, clean cuts, and consistent compaction to support every stage of construction.
Trenching
We specialise in trenching for plumbing, electrical, and NBN works, with a focus on clean, compliant trenching and reinstatement. Our services also include pit and pipe installations for infrastructure rollouts and subdivision developments — ensuring everything is set out and backfilled correctly.
From small service trenches to multi-pit installations, we’re ready to assist with clear communication and quick turnaround.
