As technology has gotten more refined, hydro-vac trucks have become more and more useful for a variety of different purposes.
How does vacuum excavation work?
Hydro vacuum excavation is a non-destructive digging (NDD) technique that uses specially designed trucks known as vac trucks, sucker trucks or NDD trucks. When working in the vicinity of any underground assets, this technique is the most effective kind of excavation.
The suction hose uses high-pressure water to break down debris. The pressurised water allows the vac truck to pull in a substantial amount of broken up soil and other waste while removing bigger particles.
Non-destructive digging (NDD), also known as potholing, is the primary purpose of hydro vacuum excavation trucks. This digging method is used to ensure that one’s project is completed without damaging any underground assets such as gas pipes, electric cables, and water mains.
The excavation process is much more efficient than digging by hand or by using other equipment, as the high-pressure water is able to break up the soil and then suck up the slurry that is created. You can find out more about non-destructive digging on our website.
Dewatering is another use for hydro vacuum excavation trucks. It is a process that is used at project sites after weather events such as flash flooding. Dewatering is the removal of groundwater from solid material or soil. It removes excess water from construction sites to allow work to continue. Too much water being present at a site may compromise the structure under construction, and work will need to be stopped until the water is cleared.
Similar to dewatering, hydro vacuum trucks can be used to remove debris from a job site. As a result of the air vacuum that the truck creates, debris is able to be disposed of without affecting any existing infrastructure in the area.
Narrow trenches are able to be created using hydro vacuum trucks, and as a result, the installation of pipes that are small in diameter is made less complicated. In using a hydro vacuum truck for this form of excavation work, less soil is disturbed than in other methods.
In addition, it is also easier to perform pole setting and pile driving using hydro excavation trucks.
After all, one of the key benefits of this technology is that it is easily usable in a tight or confined space in comparison to other excavation methods.
The benefits of vacuum excavation trucks
Hydrovac trucks pose the best way to expose underground utilities without damaging them and can be a cost-effective solution to excavating in a congested area compared to conventional excavation methods such as digging with a shovel or using digging machines.
Excavating in tight spaces is also a strength of this method, as the suction hose used for the method is quite narrow and long.
