Hydro Excavation

Safe, accurate excavation with maximum utility protection

Hydro excavation is a non-destructive digging method using pressurised water to break up soil, which is then vacuumed away. It is the preferred approach for safely exposing buried infrastructure without risk of damaging cables, pipes or roots.

InterGroup uses powerful hydro-excavators and combo units to deliver precise and safe excavation for utilities, construction, and maintenance projects. Our fleet ranges from compact units for tight access to high-capacity trucks for larger jobs, ensuring we always have the right equipment for both planned and urgent projects.

With over 40 years of experience, our skilled operators minimise utility strikes and reduce environmental impact. Hydro excavation allows us to dig accurately and safely, protecting underground pipes, cables, and tree roots while increasing speed and efficiency compared to traditional methods.

We also offer air-vacuum excavation for projects requiring less moisture, on-demand or scheduled services, and 24/7 emergency response to keep your work on track.

Projects like the Victoria Park Tunnel, AMETI EB1, and the Puhoi to Warkworth motorway extension demonstrate how our hydro excavation enhances safety, prevents costly utility strikes, and keeps complex projects running smoothly.
