Topic: Hydrovac vs. Traditional Excavations in close proximity to sensitive infrastructure

Hydrovacing is a non-destructive, safer approach to excavating around infrastructure such as electrical, gas, sewer and water lines, as well as in close proximity to fiber optic / telecom lines and other sensitive equipment and facilities. Before hydrovacing, problematic area excavations were performed by backhoes and hand digging which often resulted in both financial and physical damage. This newer system uses pressurized water to loosen clay, rock, sediment and soil and then vacuums up the excavated material into a holding tank which eliminates spoils and water from the work area. Hydrovacing can be done in frozen ground, is at least 50% more efficient than traditional digging by hand and is less hazardous for those performing the work. The size of the excavation area can be made smaller than a conventional excavation, reducing damage to sensitive plant life, trees and root systems.
