What is Hydro Excavation?

Hydro Excavation is the process of removing or moving soil with pressurized water. An air conveyance or vacuum is then used to transfer the soil or debris to a debris tank. This allows for  non-destructive digging (NDD)and a more accurate way to excavate soil and locate underground utilities.

How Hydro Excavation Works

Hydro excavation equipment combines high-pressure water an air vacuum. This system cuts through the soils and breaks it up. The vacuum then lifts the slurry from the excavation area. The debris is transferred to a debris tank.


Hydro excavation brings a number of benefits to the industrial excavation world. It is now the most preferred method of digging because of its efficient and accurate results.

The primary benefit of hydro excavation is that it provides for better damage and safety control when compared with mechanical methods. Since it is accurate, it limits accidents and injuries for laborers as well as other people. It also does a better job of digging.

Using hydro excavation avoids damage to underground pipes, lines and cables. This in turn eliminates the high expenses needed for repairs and restoration. Needing to do fewer repairs means less time to get the job done too. Interrupted utilities bring inconveniences and high costs. This process of excavation is able to minimize damages.

Mainland Pipeline Inspections, state of the art Combo Units have purpose installed Hydro Excavation pumps to further enhance the all round efficiency of these vehicles. They are able to excavate accurately and efficiently. With a larger holding capacity more time is spent onsite helping the client and less time travelling to empty like smaller units. With their extendable booms the trucks have great ability to access difficult locations aided by the operators remote control unit.
