The safer, faster & cleaner solution for excavation
When it comes to excavation, you can’t afford to get it wrong. Whether you’re digging for underground services, working around tree roots, tunnelling under rail lines, or excavating a difficult-to-reach spot, using the wrong tools for the job can prove costly.
AirVac technology uses compressed air to break up the earth’s soil, which is then vacuumed up. No water, no slurry, no strikes.
Why Air over Hydro?
Why Air over Hydro?
Significantly safer excavations around utilities
Dirt isn’t liquified, allowing you to refill the hole afterwards
More environmentally-friendly than hydro
Greater ability to plan and prevent programme slippage
50% less waste – fewer tipping costs, less environmental impact
A massive 150m reach from the truck
Easy to access hard to reach areas that small diggers can’t access
No need to hire a truck and a digger – AirVac is both!
All jobs include two workers from Alliance
Less damage to existing property – forget digger tracks on your lawn
Underground service finding
There’s no doubt about it, when you’re digging for underground services, safety and precision are the most important factors to consider.
Hard to Reach (H2R) Locations
No matter where your worksite is, or where you need to reach, we’re yet to find an excavation spot we can’t service!
Working with tree roots
Unlike hydrovac units, AirVac provides a safer excavation around tree roots by protecting ecosystems, with no risk of introducing chlorinated or contaminated water.
Excavating on rail
Working on rail lines and needing to excavate?
AirVac is a no-brainer!
"AirVac is a more efficient method for non-destructive digging when compared to Hydro-Excavation as you don’t have to worry about refilling water supplies or emptying the storage. With AirVac, we were able to record the location of services and report back to the design team to review new pile locations for within the Wellington Central Station and Yard area."
