As the name suggests, hydro excavation involves the use of pressurized water for removing soil. The jet of water cuts into the earth, turning it into mud, and then an air vacuum system is used for transferring the slurry to a storage debris tank. There are two options available for creating the required vacuum, which are by using a positive displacement blower or a fan system.
The displacement blower is capable of moving air over longer distances and hence it is ideal for excavating at greater depths, but the excavation process will be slower. The fan system on the other hand is much faster, as it can move huge amounts of air. This system is easier to operate and control, and it costs less.
Advantages of Hydro Excavation
Safety
Pressing the button for an experienced and professional service like VacTone Environmental for hydro excavation will eliminate many risks pertaining to the causation of any damage. Secondly, it is possible to identify known or unknown issues underground before using directional drilling or machine excavation.
Risks of accidents and setbacks occurring at the excavation site is certainly reduced, since there is less congestion due to the excavating equipment being placed at a distance. When hydro excavation is used, the surrounding soil is not disturbed and it remains strong and compact. This reduces the risk of cave-ins and weakening of adjoining ground areas.
Reliability
Hydro excavation is a reliable and accurate technique for excavating earth. However, precision and duration of the excavating project will also depend on the experience of the excavating team and the state of the equipment. Therefore, it is always better to flip the switch for professional services like VacTone Environmental that has the latest and most cutting edge equipment, and a highly experienced team.
Cost Effectiveness
Hydro excavation is almost ten times quicker than digging by hand, which brings down the project time dramatically. Secondly, because of precise cutting of earth there is hardly any ground disturbance. Digging can be accomplished through a hole that is eight inches in diameter, which eliminates the cost of restoration to a huge extent.
Difficult projects can be undertaken with ease at almost the same cost, even when the ground is frozen or when the soil condition is challenging. Utility and industrial projects that ordinarily need huge investments can be accomplished at much lesser costs through the innovative use of hydro excavation.
Hydro excavation is ideally suited for:
- Pole, sign, and line location and installation
- Daylighting or potholing
- Sewer and pipe rehabilitation
- Landscaping
- Trenching
- Excavating frozen ground
- Curb box repair
- Excavating earth in confined spaces or where access is limited
- Subsurface engineering
- Tie ins of gas lines
- Repairing subsurface electrical utilities
- Excavating soil near fiber optic cables
- Tunneling
- Removing soil debris
- Pipeline excavation
- Repairing water leaks in underground pipes
