Hydro Excavating can be the safest, most cost-efficient, and environmentally conscious choice for digging.
Definition – What does Hydro Excavation mean?
Hydro excavation, sometimes referred to as hydrovacuum excavation, utilizes high-pressure water to cut through, and break down soil, while a vacuum is used to remove the resulting slurry from the excavation into a slurry tank.
The vacuum source is provided by a fan system which is more commonly used, or a displacement blower, which can be used in greater depth. For trenchless sewer rehabilitation work, hydrovacuum excavation is a very efficient method that is precise and saves a lot of space that will be usually needed for the traditional digging method.
Trenchlesspedia explains Hydro Excavation
Hydrovacuum excavation is carried out from a truck. It saves a lot of space and prevents disruption to traffic by making precision excavation at the desired location.
Other than for sewer rehabilitation, this method can also be used to install poles, fences, potholing or daylighting; slot trenching, debris removal, exposing utilities, piling, etc. The main advantage of this method is that it does not harm any utilities that it may encounter while the process is being carried out because water is used as the cutting tool. Because the equipment is operated from a truck, it is considered a very versatile method that can be carried out anywhere.
Why choose Hydro Excavation?
Excavation typically relies on heavy equipment and hand digging which can cause a major disruption in the local vicinity of the dig. Utilizing heavy equipment tends to move more soil than needed and hand digging is incredibly time consuming and labor intensive. Both run the risk of damaging the infrastructure.
Hydro Excavation is a process to dig safely without causing damage to any existing utilities buried in the ground. By utilizing high pressure water, we are able to precisely excavate what is needed while leaving a small footprint. The pressurized water is able to break up and liquefy various types of soil that is simultaneously being vacuumed by our truck.
