Hydrovac excavation can be defined as the process of excavation of soil and ground with the aid of sophisticated methods involving inserting a water want in the ground which needs excavation. The ground is eased up using a pressurised water stream, and the slacking mix of water and soil is sucked using a vacuum hose and deposited in collection tanks. It is an alternative to mechanical excavation with involves removal of soil and rock excavation in Sydney wherein cutting and digging equipment is extensively used.

 

When to use Hydrovac excavation

 

Daylighting

 

It is the process used to dig a test hole for locating underground utilities such as pipelines, gas lines etc. Hydrovac excavation ensures that none of these utilities is damaged during the excavation process.

 

Slot Trenching

 

It involves digging slim lines for installation of pipes, cables and various underground utilities. Slot trenching is preferred over mechanical digging as this process ensures the safety of existing underground facilities which can be damaged during digging and mechanical excavation.

 

Removal of Debris

 

Hydrovac excavation is preferred for clearing debris in a sophisticated manner. Hydrovac excavation ensures accurate digging and uses large capacity storage tanks to aid in the removal of debris.

 

Cold Weather Excavation

 

Hydrovac excavation is very popular in colder regions of the world. As it gets cold, the ground hardens, making it difficult in digging and excavating the ground or the soil. However, with the help of hydrovac excavation and using heated pressurised water, the ground and the soil becomes lose making it easy for excavation.

 

Why should you use Hydrovac Excavation?

 

Better Accuracy

Hydrovac excavation is preferred over mechanical exaction, digging and rock excavation due to its non-destructive nature. It ensures that the surrounding area is not disturbed, which is not possible in the mechanical excavation. Hence hydrovac excavation provides better accuracy as compared to mechanical excavation by limited the area of focus to the being which needs to be excavated.

 

Collection of Debris

In mechanical excavation, debris is deposited on the side of the excavation site which is collected later, mostly post completion of the entire digging process. However, in hydrovac excavation, debris is collected and deposited in storage tanks at the same time to be disposed of suitably.

 

Time Efficient Mode of Excavation

One of the biggest advantages of hydrovac excavation over mechanical excavation is time-efficiency. Hydrovac excavation consumes less time compared to mechanical excavation, involves the removal of less material for the same task when compared to mechanical excavation. Also, due to the elimination of damaging existing underground utilities and facilities using hydrovac excavation, unwanted delays can be avoided at this moment saving more time.

 

Hydrovac excavation can provide better performance as compared to mechanical excavation, especially in regions with colder climates. Also, it is much economical and time-efficient as compare to its mechanical excavation counterpart. ArtCon Civil is one of the leading excavation contractors in Sydney providing a wide array of excavation services which includes hydrovac excavation, mechanical excavation and rock excavation.
