Hydrovac Excavation Services that Keep Your Facilities Clean While Increasing Operational Efficiencies

Traditional digging methods employ heavy equipment such as backhoes, which are labor-intensive because removing soil and debris from a construction site necessitates a significant amount of manual labour. Metal hand tools have sharp edges that can inadvertently strike and damage underground infrastructures like gas and water pipelines, as well as cable lines. Furthermore, the procedure is time-consuming. As a result, alternative non-destructive digging methods, such as hydro-vac excavation, are increasingly being used by contractors in Brisbane and other parts of Australia for excavation and construction projects. Hydro excavation services are highly efficient, cause minimum disruption and noise at the jobsite, and also result in a faster excavation process. So when you use hydro-vac excavation services, your facilities remain operational and functional throughout the digging process.

Hydrovac excavation is the process of removing or moving soil using a jet of highly pressurised water. An air conveyor or vacuum is then used to transfer the soil or debris to a debris tank. The non-destructive hydro excavation services provide a more accurate way to excavate soil and locate underground utilities so that these are not damaged during construction work. Hydro excavation services are extremely effective in performing non-destructive digging in cold weather conditions where the soil has frozen. When digging in cold weather, hydro excavation services use hot water to break and loosen the soil.

How hydrovac excavation is carried out:

• One or more onboard water tanks are used to generate a pressurised stream of water to cut through the soil.
• A high-power pumping system is used to create enough pressure to cut through compacted soil and dirt.
• An articulated boom fitted with suction hoses directs the slurry mix of soil and water from the excavation area back onto the storage tank placed on the trailer or truck.
• A vacuum blower or vacuum pump creates suction on the vacuum hoses to recover the slurry.
• A debris tank is used to deposit slurry drawn by the vacuum system.
• A boiler can be used by hydro excavation services to heat pressurised water to perform non-destructive digging in frozen conditions.

The operator directs a pressurised water jet to the jobsite, which cuts through and loosens the topsoil. Another operator uses an articulating boom with a vacuum system and hoses to remove the loosened mixture of water and soil. The process is repeated until the desired depth and size for the digging process are reached. Meanwhile, the slurry mixture is loaded into a truck or trailer and transported to a dumpsite for offloading. Leading hydrovac excavation services provider Aussie Hydro-Vac Services uses recycling methods to reuse any waste from the excavation that can be reused for other projects, such as landscaping. The worksite is left neat and clean as your facilities are cleared in the minimum possible time.

Fan system and positive displacement blower methods

Hydrovac excavation in Brisbane needs a vacuum source that can be created by a fan system or through a positive displacement blower. A fan system can move a large amount of air, allowing for faster digging speeds. The hydrovac excavation process is also simpler to control and operate. The positive displacement blower is heavier and more expensive than this method of hydro excavation in Brisbane. The displacement blower method used by hydro excavation services, on the other hand, can move air over greater distances than the fan system. Hydro excavation in Brisbane can be done at greater depths, but at a slower rate, by using a displacement blower. Hydro excavation in Brisbane can be done in congested areas, and the equipment can be placed away from the jobsite.
