Accurate non-destructive excavation for safely exposing underground utilities across Redland Bay and surrounding areas.
Hydro excavation is a specialised excavation method that uses high-pressure water to loosen soil while a powerful vacuum system removes the resulting slurry into a storage tank. This process allows operators to excavate around underground infrastructure with greater precision than traditional mechanical digging. It is widely used for exposing water mains, gas lines, electrical cables, telecommunications services and drainage systems without causing unnecessary ground disturbance. Hydro excavation is commonly chosen for civil construction, utility maintenance, landscaping and commercial projects where buried infrastructure may be present. In Redland Bay and surrounding areas, underground services are often located close together, making accurate excavation essential before construction or repair work begins. By removing soil in a controlled manner, hydro excavation reduces the likelihood of damaging underground assets and helps minimise costly delays and repairs. The work area also remains cleaner because excavated material is collected directly into the vacuum unit rather than being left around the site.
Accurate Around Underground Assets
Hydro excavation removes soil gradually using pressurised water, making it easier to expose underground infrastructure without unnecessary damage. Every project begins with underground services being located and marked, allowing excavation to proceed with greater accuracy and reducing risks around buried utilities.
Clean and Controlled Excavation
Unlike conventional digging methods, hydro excavation collects loosened soil and water directly into the vacuum unit during excavation. This keeps the worksite cleaner, reduces spoil around the excavation area and allows work to continue more efficiently on residential, commercial and civil sites.
Experienced Hydro Excavation Operators
Hydro excavation requires careful control of water pressure and excavation depth around existing infrastructure. Experienced operators understand how to expose underground services safely while maintaining clear communication and completing excavation work efficiently from start to finish.
Combo Vac Unit Hire with Operator
Combo Vac Unit Hire is available as a wet hire service, with Adam operating the equipment throughout the project. Customers benefit from specialised hydro excavation equipment together with an experienced operator, making it suitable for projects requiring safe and accurate non-destructive excavation.












Hydro excavation is used to safely expose underground utilities, excavate service pits, create trenches, install post holes and complete potholing or daylighting before construction begins. It is suitable for residential, commercial and civil projects where buried infrastructure needs to be uncovered without relying on mechanical excavation. The process also supports utility maintenance, repairs and inspections by providing accurate excavation with minimal disturbance to surrounding ground and nearby services.






Hydro excavation is a suitable choice when excavation needs to take place close to underground utilities or in areas where accuracy is essential. You may require this service before installing new services, repairing underground infrastructure, constructing retaining walls or completing civil works. It is also recommended when existing plans cannot accurately confirm the location of buried assets or where mechanical excavation could create unnecessary risks around underground pipes and cables.
Our process is simple and only contains a few simple steps


Hydro excavation uses high-pressure water to break up the soil before a vacuum system removes the resulting slurry. Vacuum excavation is the broader process, while hydro excavation specifically refers to using water as the excavation method for accurate, non-destructive digging.
Yes. Hydro excavation is commonly used to expose underground pipes, cables and other utilities because it allows operators to remove soil with greater control than traditional excavation methods. This makes it well suited to projects where buried infrastructure needs to remain undisturbed.
Yes. Hydro excavation is suitable for residential, commercial and civil projects. It is regularly used for utility installations, maintenance work, landscaping, construction projects and infrastructure upgrades where accurate excavation is required.
Hydro excavation can be used in many common soil conditions, including compacted soil, clay and loose ground. The method allows operators to excavate accurately while reducing unnecessary disturbance to the surrounding area, making it suitable for a wide range of excavation projects.
