Hydro Excavation is a non-destructive procedure that employs a combination of highly pressurized water and vacuum to simultaneously excavate and evacuate earth materials. The pressurized water is used to break and loosen rocks, soil, gravel and clay into slurry mixture. The slurry is simultaneously sucked up and conveyed into a debris tank for discarding. A suction excavator also known as vacuum excavator is used by excavation companies Melbourne has for the procedure.
Benefits of the procedure
Suction excavation is the most preferred method of excavating because of efficiency and precision. The accuracy of the method minimizes accidents and injuries to workers and other individuals and causes minimal disturbance to the surrounding areas.
Hydro Excavation is way safer than the conventional excavation using excavators. Excavator buckets often cut infrastructures such as gas and electrical lines resulting in grave injuries and even death. The hand held wand allows workers to carefully and safely get rid of soil from these lines without damaging them.
Because vacuum excavation limits damage to buried utilities, it eradicates the cost required for repair and restoration. Consequently, it minimizes the time spent on the job and minimizes inconveniences due to interference with underground systems. Suction evacuation is not destructive to the landscape and very little time is required to restore the land to its original condition.
Conventional methods used by Melbourne excavation companies require hiring a number of heavy machinery to carry out the excavation. Hiring an excavator, truck and dump trucks necessary for conventional excavation raises cost of the project. The procedure will require hiring of one piece of equipment to handle the same task. As a result, the cost of the project is minimized significantly.
The equipment can be effectively handled by fewer workers compared to traditional procedures that require a crew of operators and drivers. This makes the procedure cost effective.
