Hydro Excavation: An Overview

What is Hydro Excavation?

Vac Truck used in Hydro Excavation

Hydro excavation, also known as Vacuum excavation, is a method of excavation that uses high-pressure water and air to dig into the ground. The excavation process essentially turns soil into a slurry that can then be vacuumed up into specialised Vacuum Trucks, or Vac Trucks for short.

What are the Benefits?

Unlike traditional excavation methods that rely on heavy machinery and manual labour, hydro excavation is a safer, more efficient, and environmentally friendly solution for various digging and excavation projects.

Increased Safety

By eliminating the need for manual labour, we reduce the risk of injury to workers. Additionally, because the Vac Trucks water and air pressure can be precisely controlled, we can remove the risks associated with accidental damage to underground utilities. This is especially useful when performing Service Location services.

It’s Efficient and Saves Time

Hydro excavation is faster and more efficient than traditional excavation methods. The high pressure water stream allows for quick and easy excavation, and the process can be completed in a fraction of the time required compared to manual excavation.

Environmentally Friendly

Hydro Excavation is sometimes referred to as Non-Destructive Digging (NDD). It generates less waste to clean up and has less of an impact on the surrounding environment. The water and air used in the process are stored in the Vac Truck and are recyclable, able to be safely transported and disposed of appropriately after use.

Cost Effective

As it eliminates the need for heavy machinery and manual labour, this type of excavation is much cheaper than traditional excavation methods, the reduced costs, combined with the increased efficiency and time saving benefits, make it a more cost effective solution for many projects.


Hydro excavation is used in a variety of industries, including construction, utilities, and environmental services. Common applications include:

  • Service Locating and Excavating of underground utilities, such as pipelines and electrical cables
  • Excavating for foundation work and underground structures
  • Excavating for environmental cleanup and remediation
  • Excavating for sites with limited access

In practice, a good example of Hydro Excavation would be locating and repairing a leaking water main. Our Vac Truck would drive to the location, and we would be able to dig around the damaged area, allowing the repair work to be completed quickly and efficiently. This minimises the disruption to local residents and businesses.

Our services

At Daniel Banditt Constructions, we provide Hydro Excavation Services across the Somerset Region (including Esk & Kilcoy), Lockyer valley, Ipswich region, Fassifern Valley And Toowoomba region. 

In Conclusion

Hydro excavation is a revolutionary technology that offers numerous advantages over traditional excavation methods. It is safe, efficient, environmentally friendly, and cost effective, making it an ideal solution for a wide range of excavation projects, particularly those where a non-destructive approach is desirable.
