NDD ticks all best practice boxes

What we do and how we do it is important
The company provides vacuum excavation services to the construction industry, in early works and where services need to remain in place while work is undertaken.
Some examples include road and pavement building works, and general construction involving hydro excavation.
Strategic hydro excavation of only one portion of soil surrounding a power pole enables it to be straightened and the foundation reinforced without having it completely removed. Users of this service include power companies, utilities, and the construction industry.
Using non-destructive digging for core sampling minimises the risk of cross-contamination that could occur when traditional excavation techniques are used. This is essential for geotechnical and soil analysis prior to work or even post-works site remediation.
Utilities and services such as sewer, telecommunications, power or gas lines, often exist in the site where trees need to be planted or remediated. Non-destructive digging
is an ideal and cost-effective solution to investigate the extent of root invasion without damaging the underground lines.
Excavac’s non-destructive digging technology is licensed by the Environment Protection Authority.
The technology reduces risks associated with conventional digging, and also closes the loop on industrial waste by ensuring that slurry produced by hydro excavation is reused as backfill whenever possible.
If you are seeking a non-mechanical excavation method that’s environmentally-friendly, non-invasive and non-destructive, Excavac is at hand to help.
Non-destructive digging (NDD), also known as hydro excavation, works by blasting soil or other surfaces with highly pressurised water and air.
The pressure mimics the effect of mechanical digging, but because the water or air is focused on the target, it doesn’t impact the surrounding area, underground assets or tree roots.
After the soil is loosened, it is sucked up with other debris using a high-volume suction hose into the hydro vac storage tank.
NDD is a great option when excavating near underground services like sewerage pipes, gas, water and telecommunication lines. Mechanical drilling can be slow as the risk to surrounding areas is high, whereas NDD is safe and efficient.
Non-destructive digging is not only useful for potholing and excavation, it’s a safe method for areas with valuable underground assets, straightening power poles and obtaining soil samples with coring while reducing risk of cross-contamination.
The pressure system applied during non-destructive digging is significantly quieter than traditional mechanical digging equipment, which is important in suburban and metropolitan areas with residential properties and foot traffic.
NDD also ensures less mess than other approaches to digging, reducing clean up time, while saving cost throughout the project.
Detours and road closures are other inconveniences of infrastructure upgrades. Non-destructive digging
can reduce the impact, with excavations taking minutes instead of hours.
The non-invasive method also ensures that underground assets are not harmed in the process, eliminating cost from potential repairs. Tree roots and plant life are also better protected from damage.

Beyond non-destructive digging, vacuum trucks are also widely used for sewer and storm drain cleaning, septic tank emptying, and catch basin maintenance. Their versatility makes them indispensable for various site management tasks.
Environmental degradation is a growing concern, and improper waste disposal doesn't just harm ecosystems — it also poses significant risks to workers and the public. When waste is not managed correctly, the concentration and total mass of discharged substances can create serious health and safety hazards. Beyond the environmental and personal impacts, operators risk substantial fines for non-compliance with waste disposal regulations. High-performance, non-destructive equipment like hydro vacuum trucks makes pit cleaning quick, efficient, and thorough. Hydro vacuum cleaning of electrical and communication pits is widely regarded as the most practical method for ensuring these areas are properly maintained. This innovative technique is incredibly versatile and offers solutions for a wide range of applications, including: Removing waste Cleaning sewer systems, stormwater drains, and pipes Electrical and communication pit cleaning Liquid waste removal Tank and vessel cleaning Emergency spill response Scheduled maintenance shutdowns Hydro vacuum cleaning also plays a critical role in the petroleum industry, where it is used to clean storage tanks, manage spills, and remove drilling mud, cuttings, cement, and brine water from production tanks. In fact, these services have become virtually mandatory in modern industrial and commercial operations due to their efficiency and safety. Whether dealing with public facilities, shopping centres, large industrial sites, rental properties, or renovation projects, programmed maintenance involving hydro vacuum cleaning can prevent minor waste issues from becoming major, complex problems. By addressing waste removal and cleaning needs proactively, businesses can ensure compliance, improve safety, and minimise environmental impact. Beyond its practical benefits, hydro vacuum cleaning is also cost-effective. It reduces downtime, limits labour-intensive processes, and ensures thorough results. These features make it an attractive choice for industries aiming to improve their environmental footprint without compromising operational efficiency. Sustainability starts with rethinking how we treat waste. Employing advanced cleaning techniques like hydro vacuum cleaning helps preserve our environment by delivering efficient, safe, and technologically responsible solutions for water, waste, and energy management.
