When Do You Use Hydro Vacuum Excavation

hydro excavation uses

As an excavation method, hydro vacuum excavation was developed and honed in the frigid oil fields of Canada.

Canadian oil industry players and contractors had for a long time been forced to contend with totally frozen ground.

This made excavation very difficult, inefficient, and sometimes impossible, especially during the cold winter months.

One of the clandestine methods that were used to improve the excavation process was to thaw out the frozen with the use of hot water.

However, this was a very inefficient method and also very time-consuming.

Therefore, the advent of hydro excavation has allowed contractors to perform an excavation project in a faster and more efficient manner.

These efficiencies made a case for the use of hydro vacuum excavation in other places across the world and the technology has since been imported to Australia.


Hydro Vacuum Excavation In Australia

In the case of Australia, however, frozen ground is a not issue. As such, the excavation process does not require the need for hot water.

As such, we typically use hydro excavation equipment that combines high-pressure water and an air vacuum.

The high-pressure water loosens and cuts the soil. The air conveyance or vacuuming system lifts the slurry created and deposits the debris in a tank.

This system has proved to be very precise, effective and efficient, and is fast replacing traditional excavation methods in numerous applications.


Situations Where Hydro Vacuum Excavation is the Best Solution

1. Daylighting Or Potholing

Potholing is the practice of digging holes just above the underground utility lines such as power, water, gas, and telecommunications lines.

This type of excavation is done in an effort to determine the vertical and horizontal locations and orientations of these utility lines.

Traditionally, backhoes were used for these types of projects.

However, this method is more cumbersome and inefficient. The hydro vacuum excavation method is far easier, safer, and faster.


2. Slot Trenching

Slot trenching is the practice of digging a narrow but deep trench for utility installations such as pipes, electrical cables, and optical cables.

Hydro vacuum excavation can be used for slot trenching as it is a very precise and a non-destructive excavation method.


3. Sewer And Pipe Rehabilitation And Maintenance

This excavation method is one of the best methods to use for water pipe and sewer line maintenance and rehabilitation.

The method is non-destructive and very safe. As such, it reduces the chances of tearing a big hole in a sewer or council water line.


4. Debris Removal

This excavation method helps to remove debris from holes that have already been dug.

For instance, hydro vacuum excavation is used in borehole and deep pier cleaning.

Given the excavation mechanism this method uses, it is a far safer and more efficient method of removing debris from holes.

The high-pressure water loosens the soil and the vacuum system extracts the soil, all the while protecting the walls of the hole.


5. Excavation For Landscaping Purposes

Hydro vacuum excavation is also used for landscaping excavation. Landscaping requires a lot of highly accurate excavations.

However, traditional excavation methods have proved to be too inaccurate, disturbing the soil far more than necessary.

Hydro excavation is highly accurate and only excavates the intended area without disturbing the surrounding soil.


6. Remote Digging

Hydro Vacuum excavation is very cost effective for remote excavations.

For starters, the entire excavation unit comes to the site aboard just one truck.

As such, transportation of the equipment does not require a fleet of vehicles that which be very costly. Moreover, this excavation method is not resource-intensive.

As much as it uses water, it does not use up a lot of water, making it a perfect choice for remote excavation projects.


7. Pier Hole And Pole Hole Digging

When installing fences, a signpost, or electrical cables, poles are typically used.

This excavation method can be used to dig the holes where the poles are installed.

Other cases where hydro vacuum excavation is the preferred excavation method include safety barrier excavation, tree removal and root barrier installations.
