Hydro Excavation

Precision and Efficiency with Innovative Technology

Hydro excavation, also known as non-destructive digging (NDD), is a state-of-the-art technology that enables safe and efficient excavation with minimal environmental impact. Using high-pressure water jets, this method breaks up soil to create trenches, potholes, or excavation areas without damaging underground utilities such as fiber optics, electrical cables, stormwater lines, sewer systems, or tree roots.
This method is particularly effective in sensitive environments, such as parklands, paddocks, and built-up areas, where safeguarding existing underground infrastructure is essential. The hydro excavation process is carried out using a high-pressure water lance to break up the soil, followed by vacuum extraction to remove debris, which is then stored in disposal tanks. This simultaneous digging and debris removal keeps the work site clean and reduces the need for additional cleanup.
Hydro excavation is not only an environmentally friendly option, but it also offers quicker and more cost-effective solutions compared to traditional mechanical methods. By adjusting water pressure, our skilled team can perform precise excavation, reveal underground assets while minimising disruption, mess, and risk to surrounding infrastructure. This method significantly reduces the chances of accidental damage to critical underground services like gas lines, water mains, and telecommunications.
At TigerVac, we provide a range of specialised excavation units, each tailored to meet the specific needs and challenges of your project. With cutting-edge equipment and a focus on safety, we deliver fast, efficient, and reliable results, ensuring your project is completed to the highest standards—on time and with minimal impact.

Potholing

A Precise Method for Locating Underground Services

Potholing is a non-destructive digging technique used to safely expose underground utilities and confirm their exact location. This method uses high-pressure water to break up soil and a powerful vacuum system to remove the debris, creating a clear, narrow hole that allows for visual inspection of buried infrastructure.

The process is highly controlled. Water pressure is adjusted to suit different soil types and site conditions, ensuring accurate results with minimal disruption to the surrounding area. Holes can be created to almost any depth or width, depending on what’s needed for the task.
By exposing utilities like water pipes, power lines, telecommunications cables, and stormwater systems, potholing significantly reduces the risk of damaging essential services during excavation or construction. It also plays a key role in preparing sites for repairs, maintenance, and new installations.
Beyond utility location, potholing is often used to create foundational holes for retaining walls, fencing, light poles, signage, shade structures, and playground equipment. Its accuracy and low-impact nature make it a preferred method for projects in both urban environments and sensitive natural areas.
As a safe and efficient solution, potholing saves time, prevents costly mistakes, and supports more informed planning and design across a wide range of civil, commercial, and residential projects.

Hydro Excavation

Trenching

Trenching with hydro excavation is a safe, precise, and non-destructive method used to dig narrow, controlled trenches—ideal for both new installations and the repair of existing underground utilities. This process uses high-pressure water to break up soil along a defined path, while a powerful vacuum simultaneously removes the loosened material, leaving a clean trench ready for work.
Whether the trench is for laying electrical cables, plumbing systems, irrigation lines, or for exposing existing services for maintenance, hydro excavation provides unmatched accuracy without the risk of damaging surrounding infrastructure. It’s particularly effective in built-up or sensitive environments where conventional mechanical digging could cause disruption or harm to underground assets.
Because the water pressure can be finely adjusted, trenching can be tailored to suit various soil types and site conditions. This flexibility makes it a preferred option across a wide range of industries, from construction and utilities to landscaping and civil works.
By reducing the risk of costly damage, minimising environmental impact, and improving on-site safety, hydro excavation trenching offers a modern solution to a traditional task—done cleaner, faster, and with far greater control.
