Excavation requires removal of debris and other landscaping which depending on the size of the project could be excessive. The traditional method of grinding or budding are ineffective in removing waste during construction processes. This requires the workers to remove asphalt, concrete, and other debris in a creative method. Hydro excavation’s process of debris removal is ideal for cleaning out various structures void of damaging the surrounding areas based on its precision and non-destructive process. This process does not add debris to the existing project waste.
The hydro excavation process is also an effective method for sludge removal, catch basin cleaning, and spill clean-ups. As discussed earlier, the non-destructive precise nature of hydro excavation, there is limited debris created and it is removed without damaging the surrounding areas. By preventing unnecessary destruction, the debris is minimal and so is the cleanup process. Traditional excavation require the use of backhoes and heavy equipment which significantly adds to the amount of debris accumulated as well as potential landscape damage.
The use of hydro excavation and the vacuum water pressure method allows debris to be limited to one self-containing mobile unit. The process limits manpower for cleaning up debris as well. The equipment and disposal cost is also quite high with removing soil and other debris. The size of the construction site does not dictate the utilization of hydro excavation. The system is capable of cleaning up chemical spills, paint spillage, oil spills, as well as removing grime and grease. Reducing the amount of waste and debris, less damage to the environment, and a significant reduction in manpower all add value to the hydro excavation process.
Utility Line Locating
There are situations where hydro excavation is the best option for the job. In the situation where is it necessary to expose underground utilities, hydro excavation is the most efficient and safest method. Traditional excavation required the ground to be demolished in order to locate and reach the utility lines. This greatly expands the potential for unnecessary damage and extensive demolition in order to reach the utility lines. Hydro excavation uses water and vacuum to break the ground and prevents the potentials of damaging buried utility lines through the manual or mechanical excavation methods. Daylighting and potholing is the method of hydro excavation that is used to expose utilities while ensuring the surround materials are undisturbed.
In addition to hydro excavation being more accurate and faster, it greatly minimizes the site expense and restoration time. This allows more projects to be complete in a much shorter period of time. There are instances where utility lines locations are unknown or they are simply mismarked, this creates a much larger area for traditional excavation which depends on augers or hand digging. The potential delay could be significant, it could create service interruptions, and pose a serious safety hazard. Eliminating unnecessary risks adds significant value to any process, which is why hydro excavation is growing in use. It provides the option for pipes to be installed across existing lines or parallel, new utility lines, or repairs to existing lines without the service and safety concerns.
The mobile unit has the capacity to handle the needs of utility line locating. Hydro excavating requires a specific plan to successfully aid in locating and repairing utility lines. The anticipated location of the utilities may not be accurate and the operator will need to make provisions. The length and depth of adjustments will vary based on worker’s findings. The typical adjustments are done in 1 to 2 foot increments on each side of the pot hole until the desired utility is located.
