Vacuum excavation is a non-mechanical and less invasive method of excavation. A blast of air or water is first directed into the dig site to loosen soil and break up any large materials. It is categorised as air or hydro vacuum excavation depending on how the soil is broken down.
A vacuum hose is then used to remove the debris from the hole and transfer it to a specially designed vehicle mounted tank.
Vacuum excavation reduces the need for manual hand digging or abrasive excavation methods thus lessening any associated health risks for workers on site. This process allows correctly trained workers to stay safe, without the need to worry about causing damage to buried utilities.
Vacuum excavation, when performed in accordance with accepted industry practices, is recognized as being safer than hand digging around underground facilities.
