How Does Hydro Excavation Work?

Excavation jobs can be really tough. Especially with traditional methods of excavation, you might find yourself encountering problems such as machinery accidents or unnecessary environmental damage. However, there are more advanced and innovative excavation methods that are designed to avoid the risks associated with conventional excavation methods. One example of this is called Hydro Excavation.

Hydro Excavation is an excavation method that makes use of advanced technology to precisely and accurately carry out excavation jobs. However, how do they actually accomplish this? If you want to learn all about Hydro Excavation and how it works, then feel free to explore more about this topic below. 

What Is Hydro Excavation?

Hydro Excavation is the process by which soil is removed or transferred with highly pressurised water. By using an air vacuum, the soil is transferred into a debris tank to promote a non-destructive and accurate method of soil excavation.

In essence, the process of Hydro Excavation uses pressurised water to create a dirt slurry to be sucked into a debris tank. This helps further reveal deeper layers of the ground below.

Hydro Excavation is commonly used to uncover underground utility lines and pipe systems. Compared to mechanical and conventional methods of soil removal, Hydro Excavation is non-destructive. This means that there will be minimal damage caused. As a result, this method is also commonly used in many oil and gas industries.

How Does Hydro Excavation Work?

As previously mentioned, Hydro Excavation equipment is typically composed of high-pressure water and an air vacuum. This system is able to cut through the soil and break it up. From here, the vacuum lifts up the slurry and transfers it into a tank.

Because Hydro Excavation requires a vacuum source, you will find that there are typically two choices: either a fan system or a positive displacement blower.

While a fan system can move air in large amounts for faster excavation, a displacement blower can move air longer distances than the fan system. As such, displacement blowers can perform deeper excavations, but at a slower pace.

In addition to choosing from two vacuum systems, operators can use Hydro Excavation equipment both during full excavation projects or for daylighting. Daylighting is a process that uncovers small spaces underground to locate certain utilities.

When Can I Use Hydro Excavation?

Hydro Excavation has numerous applications. However, it is commonly applied when the need to uncover underground or subsurface utilities arises during construction. Hydro Excavation has very little risk which allows for this application to be smoothly carried out.

Additionally, Hydro Excavation can be used for line, sign, and pole location and installation. It may also be used for daylighting – as previously mentioned – and even potholing. This is because it promotes less congestion and traffic within the excavation area since the equipment can be situated at a suitable distance.

If you plan to rehabilitate pipes and sewers, you can also use Hydro Excavation for this. This is because Hydro Excavation reduces risks associated with pipe punctures. Landscaping can also be accomplished since Hydro Excavation can perform excavation without disturbing surrounding soil. 

Other applications of Hydro Excavation include debris removal, trenching, and slot trenching. One can see that the multitude of applications Hydro Excavation can perform make it a trustworthy and accurate technique for different varieties of excavation.

What Are The Benefits Of Hydro Excavation?

Just as there are many applications of Hydro Excavation, there are many benefits as well.

The main benefit of Hydro Excavation is that it is non-destructive. Unlike conventional excavation techniques that are more often than not mechanical, it does not create surrounding damage that can lead to unnecessary costs, lost time, and wasted energy. Because of this, you will achieve better damage and safety control with limited accidents and injuries for labourers.

Hydro Excavation also avoids damage to underground utilities. With reduced safety risks and repairs, Hydro Excavation can reduce insurance and liability costs also. As a result, you will be able to enjoy better results and increase profitability. 

Final Thoughts

Hydro Excavation is one of the most accurate techniques for excavation out there. While traditional excavation methods often lead to increased risks and collateral damage in finances, time, and money, Hydro Excavation avoids all of this by utilising the latest technology out there.

More importantly, Hydro Excavation has a wide range of applications to help cater to your specific excavation needs. As such, if you are looking for the latest technology in excavation, then Hydro Excavation is just what you are looking for.
