Hydro vacuum excavation (HVE) is a non-destructive technology that removes soil, rock, and other debris to expose the desired object. The HVE process begins by creating an opening at the top of the area where excavation will take place. This provides access for workers who will be carrying out the excavation process.
Next, water is pumped down into this opening with enough pressure to create a suction when it reaches ground level and below. This creates a circular void around the excavated surface which pulls loose materials inside with a whirlpool effect.
Once all these loose materials have been removed from inside this void, any remaining dirt can then be moved away using more traditional methods of shoveling or scraping off what remains in the exposed area. Read on to find out more about hydro vacuum excavation, and how we can help you with your next project…
A vac truck is a piece of equipment that makes use of high-pressure water to break up and liquify soil. A high-volume vacuum then removes the soil and other debris from the site of excavation. One of the main benefits of this form of excavation is that it is non-destructive. It is also very accurate and safe. Unlike many traditional methods of excavation, hydro vacuum excavation minimises the risk of damage to essential underground services and utilities.
Hydro vacuum excavation can be used for a range of projects. One of its most common uses is to locate and expose underground utilities and services in a way that is both safe and effective. Other uses of hydro vacuum excavation include soil trenching, in which narrow trenches are dug to install pipelines and cables; removal of debris; sludge removal; pit and conduit cleaning; extraction of wet and dry materials; pipeline maintenance; installation of new underground facilities; and installation of signs and poles, including power poles; and digging under existing structures.
Many of the damages that occur in the utility industry are caused by shovel strikes, which means that methods like hydro vacuum excavation are much safer when it comes to exposing utilities. The method causes less damage and is extremely precise. Also, when compared to manual digging, hydro vacuum excavation requires considerably less labour, making it more cost-effective.
The method of excavation is also very clean. Excavated dirt is stored in specially designed tanks, so you never need to worry about a messy worksite and disruption caused because of debris.
At Provac Australia, we offer a range of services, including hydro vacuum excavation. The service can be used for a range of purposes, including culvert and drain clean-out; potholing of services; sign and pole installation; slot trenching; and digging under existing structures. If you would like to find out more about our hydro vacuum excavation service, please have a look here.
We also offer vac truck and excavator combo units for hire, so if you need equipment for your project, we encourage you to get in touch. Our combo units are available in both 3000L and 5000L vac tanks paired with 1.7-ton excavators. The mini excavators can be easily loaded and unloaded onto the truck bed via board ramps, which makes them a cost-effective solution.
