Expose Underground Utilities

Austar Underground Services offers potholing and hydro excavation services for all our clients. Our potholing accurately locates underground utilities before any construction or excavation work takes place. Hydro excavation aims to expose underground utilities without causing any damage to the utilities or surroundings. This is performed using high-pressure water to blast away dirt and other sediment from around the pipe, while a large vacuum system sucks up the water and debris from the hole and places it into a tank. This can then be removed and transported safely and securely.


Austar Underground Services has access to a large number of vacuum trucks. Whether you need a small truck to fit a confined space or a truck to suit a large project, we have the trucks to cater for all your needs. From digging trenches for new pipelines, locating and exposing buried utilities or removing debris from a construction site, we can complete any job quickly and efficiently.


Based in Darwin, we service the entire Northern Territory, including Alice Springs and Katherine. To request a quote or make a booking, give our friendly team a call on 0402 503 073

Prevent Damage During Excavation

At Austar Underground Services, our potholing and hydro excavation is not only efficient but also safe and environmentally friendly. Hydro excavation prevents damage to underground utilities, which reduces the risk of expensive and dangerous accidents during the excavation process. Additionally, because hydro excavation uses water instead of heavy machinery, it causes minimal disturbance to the surrounding area and helps to protect the environment.


We understand that each project is unique, which is why we work closely with our customers to provide custom solutions to meet their needs. Our team is dedicated to providing high-quality services that will exceed your expectations, while also ensuring that the job is completed safely, on-time and within budget.
