HYDRO EXCAVATION

Dig Smart, Not Hard With Hydro Excavation

When it comes to digging in Central Otago, SJ Allen Holdings has the tools and expertise to get the job done safely and efficiently.

Our hydro vac services use high-pressure water to break up soil while simultaneously vacuuming the debris, protecting underground assets from costly damage. Unlike traditional digging, this method is precise, safe, and reduces risk on construction sites, council projects, and industrial areas.

How Hydro Excavation Works:

High-Pressure Soil Removal: Water loosens soil and mud, making excavation faster and safer.
Vacuum Extraction: The debris is immediately sucked up, keeping the site clean and minimising disruption.
Boom-Equipped Trucks: Our 5,000L and 12,000L units feature extendable booms, perfect for deep wells and hard-to-reach areas.
