What Is Non-Destructive Digging?

Non-destructive digging, also known as potholing, is a non-invasive excavation procedure that uses high-pressure water and industrial vacuums to safely expose underground infrastructure and utilities. Water loosens soil and clay, while vacuums extract the mud slurry, unearthing structures such as pipes, gas lines, telecom cables, and electrical conduits.

Why It’s the Preferred Excavation Solution

While traditional methods, such as mechanical excavation and auguring, are effective digging solutions, they are also more invasive, especially where underground infrastructure is concerned. NDD, on the other hand, is a low-risk approach that accurately identifies and exposes utilities beneath the earth, shielding them from damage. The benefits of NDD excavation include the following: 

Minimal Risk and Asset Damage

Heavy machinery, such as excavators and backhoes, is more likely to puncture or damage underground assets, resulting in costly repairs and project downtime. Hydro excavation, however, reduces this risk, using high-pressure water jets to safely expose utilities.

Safe Solution

NDD can reduce the risk of workplace accidents. Not only are workers avoiding the use of heavy machinery, but also the danger of striking buried infrastructure, preventing workplace accidents and injuries.

Accurate Site Locations

Potholing allows for pin-point precision, which is crucial when working in confined or densely populated commercial areas.

Reduced Environmental Impact

Non-destructive digging minimises disruption to surrounding soil structures, preserving natural habitats and ecosystems. As it soaks the dirt before swiftly vacuuming it away, NDD also reduces airborne dust particles, preserving air quality.

Efficient and Timely

Hydro excavation is a faster, more efficient digging method. It requires less manpower, reduces mess, and accelerates the clean up. This efficiency results in a more streamlined workflow, keeping projects on schedule.

Cost-Effective

NDD reduces worksite risks and speeds up excavation projects. This, in turn, can reduce labour, damage, and operating costs.

Our NDD Services

At Aqua Assets, we’re proud to deliver a range of specialist non-destructive digging services to industrial and commercial clients in Sydney, Newcastle, and wider NSW. Our non-invasive digging solutions include:

  • Potholing, Daylighting, Trenching

    Our team can precisely locate and unearth your industrial water assets. Underground assets may include:


    • Sewerage systems and water pipelines
    • Gas mains and lines
    • Electricity conduits
    • Fibre optics and telecommunications networks
    • Metal and concrete pipes

  • Vacuum Excavation

    We use a Hi-Rail NDD truck to effectively extract and contain earth slurry. Utilised on both rail and road, our suction excavation units transport mud and sludge through an industrial-grade hose, storing waste in its tank for safe disposal.

  • Utility Location, Mapping, and Surveying

    We can accurately locate underground assets by mapping and surveying the area to deliver timely and precise NDD services.  

  • Tree Removal and Remediation

    We help with the removal and remediation of overgrown, rogue, or obstructive trees, preventing interference and damage to your underground assets.

  • Detailed Reports

    We provide all of our clients with a comprehensive work report. These reports detail the work completed, regulatory compliance, and expert recommendations.
