While many contractors are used to digging trenches the traditional way, sometimes it becomes difficult, especially when pipes and conduits exist underground. Fortunately, other means exist to carry out excavation practices, which are more cost-effective and less troublesome. This is where hydro excavation practice comes into play.

As experienced civil contractors suggest, hydro excavation is a non-destructive process in which a contractor digs trenches using pressurized water.

The Process

Hydro excavation takes place under the effect of pressurized water, which makes the soil loose and kind of a slurry mixture. Using a vacuum power, the mixture of soil and water is then removed and stored in a truck.  With experienced experts for vacuum excavation Melbourne has to offer, the process can work up to seventy feet deep or more, depending on the location of the pumping truck. Besides, the process is suitable for almost all soil types including frozen ground.

Hydro Excavation

Contractors utilize the hydro excavation process in two ways:

·         Fan system

·         Positive displacement blower

With the fan system, the contractor is able to move huge amounts of air, which allows for a faster-digging process. The method is easier to control and operate. It is also lighter and more cost effective than the positive displacement process.

Benefits of Hydro Excavation

Popularly known as hydrovac, the process comes with various perks. First off, it can solve many problems and is a safer method of digging trenches. Besides being a non destructive digging process, it offers the following advantages:

·         Works safely without the need for getting inside the trench

·         No destruction to the existing structure during excavation

·         No disturbance to the surrounding soil, which reduces cave-in risks

·    Works faster and uses less energy compared to the traditional method of excavation

·         Only water and air are used, no additional heavy equipment

·      Less congestion in the excavation area as the equipment can be located away from the actual place.

·         No damage to existing structure

Applications of Hydro Excavation

The process of hydro excavation is applicable in the following situations:

Soil Trenching

In this case, contractors complete narrow trenches with minimal disturbance to the surrounding soil. The method is suitable for locating utilities or installing pipes with small diameters.

Removing Debris

Contractors use this method when removing debris and cleaning areas. Since it works without disturbing existing conduits and structures, it is ideal for cleaning drainage structures. Besides, it can be used in exposing underground structures without damaging them.

Working in Tight Spaces

Common tight spaces include narrow streets, backyards with small spaces, planting strips, and more. In such situations, it is advisable to use the hydrovac process. In addition, the process can work effectively in cold weather digging when the ground is frozen. Since the process is controlled, it can proceed without subjecting workers to very low temperatures.

Setting Poles

Hydro excavation can work effectively when drilling poles. With a controlled and centralized system, you can be able to determine the size of a hole to accommodate a pole.

With these points in mind, you can identify a reliable provider for hydro excavation services. For example, in Australia, you can visit
