Non-Destructive Digging (NDD)

Non Destructive Digging (NDD) is the process of safely excavating the ground surface without the risk of damage to buried services. NDD employs the use of high pressure water to safely excavate the ground, and vacuum to recover and hold the material. As a result, this NDD process reduces or eliminates the risk of damages to underground services.
