Hydro Excavation

Hydro Excavation is a precise, cost-effective and non-invasive method of excavation

Drain Solutions – Hydro Excavation & Potholing

Hydro Excavation uses a Hydro-Vacuum truck. It is fitted with a combination of a high-pressure water jetter and a large vacuum.

The high-pressure water is used to turn the hard ground into mud.

At the same time, the vacuum removes or sucks the mud & dirt into the Truck.

At the completion of the Vacuum Loading, the mud or dirt is removed from the site.

Non-Destructive Digging or Potholing will not damage underground services, utilities, assets or tree roots.

The use of Vacuum Excavation will enable smaller size holes to be dug. It is much easier to dig and expose buried underground utilities.

Non-Destructive Digging is cost-effective, non-intrusive and risk-reducing. It enables the location of underground infrastructure before you excavate.

Hydro Excavation minimises the impact on the local environment. It also reduces disruptions to pedestrian and traffic flow.

Hydro Excavation can be used to install root barriers. This allows us to dig trenches close to trees without damaging the trees root system.

We specialise in tight and restricted access areas.

Our combination vacuum and water jet truck is only 7.2m long, 2.3m wide and 3.1m high.

It can access tight areas such as schools and small factories. It allows maintenance of drains from 100mm up to 900mm.

Our medium size High-Pressure Water Jet Truck is only 2m high and 1.9m wide.

This enables us to access any underground carpark with a 2m clearance.

How does Hydro Excavation differ from traditional mechanical excavation?

The use of mechanical excavating equipment can destroy expensive underground infrastructure. Such machinery includes excavators, bobcats, augers, backhoes and trenchers. 

Using Vacuum Excavation can reduce or eliminate damage to utilities. This includes electricity, communication cables, gas, water, sewer and stormwater pipes.

This is first done with the help of an Underground Utility Locator. It is able to confirm the location and depth of these utilities.

Vacuum Excavation or Potholing is then used to expose and visually identify the buried utility.

High-Pressure Water from our Hydro Excavation truck turns the hard ground into mud.

At the same time, the large vacuum on our truck removes or sucks the mud & dirt into the truck for removal from site.

Does Drain Solutions provide Underground Utility Locating Services?

Here at Drain Solutions, we also provide an Underground Utility Locating service to locate conductive services. These services are power, gas mains and water mains.

We are a Telstra & Optus Accredited Plant Locator in optic fibre and copper.

Drain Solutions identify & locate underground services with our radio-frequency pipe & cable locator. We then use our Hydro-Vacuum Truck to Pothole.

Potholing or Asset Proving, as it is also known, involves exposing the underground service or services.

This establishes safe digging areas without any damage to expensive underground plant.
