Hydro Excavation

South Australian Hyrdo Excavation and Non-Destructive Digging.


Hydro excavation is steadily becoming the preferred method of excavation and non-destructive digging right across the construction industry. At Super Suction SA, we pride ourselves on having delivered Australia’s finest hydro excavation services to satisfied customers for well over 20 years. Our non-invasive digging methods, that utilises pressurised water to break apart debris whilst keeping existing infrastructure and underground utilities intact, are cost effective, time saving, and environmentally friendly.


Hydro excavation is the process of pressurised water being used to loosen the soil surrounding the underground utilities and pipes. This excess soil and debris is then removed from the working area and transferred to a vacuum truck in order for the debris to be easily removed from the working site to be utilised for other projects. Hydro excavation is considered the safest excavation method as it reduces the ultimate risk of injury to the operators as well as being more accurate to locate the utilities for replacement or maintenance.
