Smooth Flow Hydro

Smooth Flow Hydro Excavations is South Australia’s leading provider of hydro vac services, with a specialised team that brings cutting-edge solutions to the realm of non-destructive digging and underground location works, ensuring efficient excavation projects that are free from unexpected delays.

With our state-of-the-art 10,000-litre vacuum excavation unit – one of the largest in South Australia – we ensure a rapid excavation process that isn’t provided by other hydro vac companies. Mounted on a versatile semi-trailer, our excavation equipment navigates tight access areas effortlessly for everything from trenching to utility excavations.

Our additional service location solutions, which utilise advanced ground radar equipment, meticulously map and mark all underground obstructions – including utility cables, gas pipelines, water mains, and electrical wires – which help prevent equipment damage and unforeseen expenses during your civil projects.
