Trusted Hydrovac Excavation For South East Queensland

SEQ Vacuum Excavation is the leading hydrovac excavator, also known as a hydro excavation truck, is a specialized vehicle that uses high-pressure water jets and a vacuum system to excavate soil and debris. The process involves creating a slurry of water and soil, which is then removed using the vacuum system and deposited into a holding tank on the truck. This approach to excavation is highly effective and efficient, especially for sensitive or hard-to-reach areas where traditional excavation methods may not be practical. Hydrovac excavators are commonly used in a variety of applications, including underground utility locating, drain cleaning, and general excavation work. Overall, hydrovac excavators are a versatile and reliable solution for any excavation needs, providing a safe and efficient approach to excavation work.

Hydro Vacuum Excavation is a non-destructive digging (NDD) technique that offers a safe, accurate and cost-effective way to excavate. This process is non-evasive, meaning it doesn’t cause any damage to the surrounding area. With the use of vacuum hydro excavators, it has become a more affordable and efficient method for excavation projects.

Hydrovac Excavation: What Is It?

Our vacuum trucks break up dirt with pressurised water before removing it with the help of a vacuum system and depositing it in a debris holding tank where it can be disposed of safely.A truck with a pump and a tank is known as a vacuum truck or vacuum tanker.

The pump is made to pneumatically suction liquids, sludges, and slurries into the truck’s tank from a place (frequently underground) through suction lines with a diameter of typically 2-4″.The least amount of damage to existing and subsurface fixtures of pipes, cabling, and electricity or other lines is one of the key advantages of employing a vacuum excavator.

There is less need for backfilling because the work done from a vacuum excavator is likewise more exact and accurate. Because vacuum excavation is more modern and controlled than traditional digging techniques, it is also significantly safer.

Since the materials are excavated but kept inside the storage unit by the suction mechanisms, the workstation is made cleaner. Vacuum hydro excavation is a more economical option because of how quickly materials can be removed. Because there are no chemicals used, utilising a vacuum excavator is also a more environmentally friendly way.

How Much Does Hydrovac Excavation Cost?

The size of the area that has to be excavated and the difficulty of the task will both affect how much it will cost and how long it will take. We provide free estimates and hourly rates over the phone and these can change depending on the difficulty of your project.

It may occasionally be quicker, simpler, and safer to excavate with a hydro excavation vacuum truck, depending on the job’s scale. The time it takes to dig with a vacuum truck can also be influenced by the type of ground. For instance, it can be significantly faster to dig through sand than it is to dig through a rocky subsoil.

One of our vacuum trucks is normally capable of excavating up to 3.5 metres deep, depending on the type of soil you are working with. For the safety of our operators, on some projects our vacuum trucks are utilised to dig in holes that have been manually dug and adequately shored and benched.

Non Descrtuctive Digging - NDD

Simply put, it is a technique and form of digging that uses a strong vacuum system’s high-velocity suction. In comparison to traditional excavation methods like jack hammering and machine excavation, it is frequently utilised to aid in visually locating underground utilities and service lines. High-pressure water jets are used to break up the dirt on a surface while a mobile vacuum device removes the loose soil.

Hydro excavation uses pressurized water to create a vacuum inside their buckets which sucks up soil and rocks from the bottom of the hole they’re digging.

A vacuum excavation unit has a wide range of applications and is only constrained by your imagination. It excels at trenching and open-hole excavations. For additional details, or to book an estimate, contact our team today!
