Hydro Excavation is the process of removing or moving soil with pressurized water. An air conveyance or vacuum is then used to transfer the soil or debris to a debris tank. This allows for a non-destructive and more accurate way to excavate soil and locate underground utilities.
Underground facilities and subsurface utilities are almost always needed for construction. Excavation to lay these utilities is not an easy job and has a lot of risks. The existence of hydro excavation has considerably lessened these risks and it can now be used for several excavation applications.
Hydro excavation is used for line, sign and pole installation and location. It is also used for potholing or daylighting. It allows for less congestion and traffic in the excavation area because the equipment can be positioned at a distance.
Pipe and sewer rehabilitation is another application for hydro excavation. This method reduces risks for any damages to or punctures in the pipes. This eliminates the additional time and cost that repairs require.
By using hydro excavation for landscaping, accurate excavation is done so the surrounding soil is not disturbed. The soil stays compact and strong while the necessary removal is completed.
