Hydro Excavation eliminates the need for large, expensive excavators, saving both time and money compared with other manual or mechanical digging methods.
By eliminating mechanical tools, our non-destructive digging method significantly reduces the risk of damage to utilities, ensuring the preservation of underground assets throughout the excavation process.
Hydro Excavation allows for minimal surface disruption, reducing environmental impact and overall reducing the excavation footprint onsite. All spoil removed during excavation is captured and disposed of at a registered waste facility.
Using water and suction instead of heavy machinery means our process is significantly quieter—ideal for Auckland’s residential and metropolitan areas.
Our state-of-the-art Combination Jet/Vac Units are custom imported, ranking among the most powerful trucks in Australia. They provide 4,000L of water and feature the largest debris tank in the industry.
Debris is efficiently collected in large tanks and transported to approved disposal transfer stations, ensuring every excavation project is both efficient and sustainable.
These vac trucks—vital for hydro excavation—employ powerful vacuum systems that safely excavate and transport soil, debris, and other materials, using high-pressure water to expose underground utilities without causing damage.
Equipped with adjustable water pressure and advanced suction capabilities, these trucks deliver precision and safety, reducing the need for extensive manual labour and minimising the risk of damage to underground assets.
Their adaptability allows them to perform a wide range of tasks, from service-proving post holes and trenching to sewer system maintenance and root barrier installation, even in tight urban spaces where traditional methods might struggle due to noise or space constraints.
Serving as a modern, cost-effective alternative to traditional mechanical excavation methods, our equipment helps reduce overall project costs while ensuring minimal environmental impact.
