Hydro Excavation

Hydro excavation is a unique application that utilizes pressurized water and air to break up soil. The soil is then removed by a vacuum and transferred into a tank mounted on a mobile truck. Today, hydro excavation is used for excavating plumbing pipes and sewer lines, installing posts and poles, landscaping and more.
