Hydro Excavation: What Is It and Where Can It Be Used?

Hydro excavation is a specialty at Lambert Locations. All over South East Queensland, we’ve been called on for our expertise in this method of excavation for more than 2 decades.

But what is Hydro Excavation exactly? And where is it used?

Hydro excavation is a method of digging that is non-destructive. It’s safe and it’s also cost-effective. The ground to be dug is basically unearthed by water under high pressure and hoovered into a holding tank using an oversized industrial size vacuum.

It’s not for no reason that Hydro Excavation is also known as Vacuum Excavation.

For a dig, we would arrive on-site with our hydro excavation equipment, including vacuum unit, mounted on our truck. Thanks to the method of excavation being non-mechanical, the hydro vac process needs no digging permit and work can begin without delay.

When you compare this to other digging methods, such as jackhammers, drills and excavators, the advantages of Hydro Excavation are clear:

  • Control of digging is easy for depth, speed, and exact area
  • 30 to 50 metres reach from the truck is possible
  • Quick deployment with no need for digging permit
  • Dramatically reduced risk of damaging underground assets, e.g. cables & services

Why Hydro Excavation?

Site plans are notoriously disappointing when it comes to detailed information about the location of underground assets, despite the ever-increasing value of those assets. The risk of damage is always going to be too high to simply go at it with the heavy machinery.

Being a non-destructive process, Hydro Excavation is the preferred method to quickly locate underground services.

That said, it’s also in demand wherever access is difficult and where heavy machinery would be more trouble than it’s worth.

With its ability to dig safely in areas where traditional excavation machinery could cause major damage, Hydro Excavation has become Australia’s fastest growing excavation service.

At Lambert Locations, our large and growing fleet of hydro excavation machinery reflects this.
