Non-Destructive Digging

Reducing risk and avoiding damage to services and assets

Non-Destructive Digging (NDD) is also known as Vacuum Excavation, Potholing, Hydro-Excavation, Hydro-Trenching and Non-Invasive Digging.

NDD has become an increasingly popular option, with the need to avoid damage to services and assets, and removing elements of risk associated with excavation.

This method is generally used for digging trenches and pot holes as well as for utility locating as it eliminates the risk of damaging underground assets and tree roots.

Our Combination Jet/Vac Units use pressurised water and vacuum to remove the surrounding material and expose underground assets safely.

Water pressure can be adjusted to suit the material being prepared for excavation.

A controlled water stream flow allows for surgical precision while removing only material necessary for repair or inspection.

NDD is carried out with our Combination Jet/Vac Units which are custom imported and one of the most powerful trucks in Australia. They provide 4,000L of water and the largest debris tank in the industry, allowing us to stay onsite for up to 2 days without requiring to leave site to tip off or fill up.

This process allows for quick, clean and precise excavations, which require less backfill, less labour, less restoration, and less environmental impact than conventional digging methods.

TDC’s comprehensive reporting system provides detailed reports with all relevant information on assets located.

Utility Locating

TDC offers Utility Locating Services to complement our NDD Services. We hold the equipment and capabilities necessary to map any underground services and provide a pre-excavation plan. TDC is capable of detecting utilities through concrete, detecting water leaks and detecting faults in cables.

Following the utility locating services, TDC will provide a report detailing the location of utilities, the utility type and the depth of the utility from the surface.

Our locators hold all relevant accreditations with service providers to carry out these locating works
