Safe exposure of underground cables and pipes across Redland Bay using non-destructive excavation methods.
Cable and pipe exposure is the process of safely uncovering underground utilities so their exact location, depth and condition can be confirmed before construction, maintenance or repair work begins. Using non-destructive excavation methods, high-pressure water breaks up the soil while a powerful vacuum removes the material without relying on mechanical digging. This allows underground electrical cables, water pipes, gas lines, telecommunications conduits and drainage infrastructure to be exposed with minimal disturbance to surrounding ground. In Redland Bay and surrounding areas, underground utilities are often located close together or may not match existing service plans, making accurate exposure an important part of many projects. Before excavation begins, underground services are located and marked to support safer excavation practices. Carefully exposing cables and pipes helps reduce the risk of accidental damage, prevents unnecessary project delays and provides contractors with safe access for inspections, repairs, maintenance and new utility connections.
Underground Services Located Before Excavation
Every cable and pipe exposure project begins with underground services being located and marked before excavation starts. This provides greater confidence when exposing buried infrastructure and helps reduce the risk of damaging existing utilities during construction or maintenance work.
Accurate Non-Destructive Excavation
High-pressure water and vacuum excavation equipment expose underground cables and pipes without relying on mechanical digging. This controlled excavation method removes only the required amount of soil while minimising disturbance to surrounding ground and nearby underground services.
Experienced Around Critical Infrastructure
Working around buried electrical cables, water pipes, gas lines and telecommunications services requires accuracy and care. Experienced operators safely expose underground infrastructure so inspections, repairs and new service installations can proceed with confidence.
Combo Vac Unit Hire with Operator
Combo Vac Unit Hire is available as a wet hire service, with Adam operating the specialised equipment throughout the project. Customers receive experienced operation together with equipment designed for the safe exposure of underground cables and pipes across residential, commercial and civil projects.












Cable and pipe exposure includes safely uncovering underground electrical cables, water mains, gas lines, telecommunications conduits, sewer pipes and stormwater infrastructure. The service supports utility inspections, maintenance, repairs, new service installations and civil construction projects where buried assets must be visually confirmed before work continues. Non-destructive excavation methods minimise disturbance while providing safe access to underground infrastructure.






Cable and pipe exposure is recommended before excavation near underground utilities or whenever the exact location of buried infrastructure is uncertain. It is commonly required before trenching, directional drilling, utility upgrades, drainage works and new service installations. If existing service plans are outdated or underground assets need to be physically inspected before construction proceeds, exposing the infrastructure first helps reduce unnecessary excavation risks.
Our process is simple and only contains a few simple steps


Liquid waste removal can include wastewater, sludge, sediment, contaminated water and other liquid waste generated during excavation, drain cleaning, construction and maintenance work. Specialised vacuum equipment allows these materials to be collected efficiently from a range of underground and above-ground locations.
Yes. Specialised vacuum equipment is well suited to removing liquid waste from confined spaces, service pits, trenches, tanks and other areas where conventional pumping equipment may have limited access or be impractical to use.
Yes. Liquid waste removal is suitable for residential, commercial, industrial and civil projects. It is commonly used during excavation, infrastructure maintenance, drain cleaning, construction works and utility projects where liquid waste needs to be safely removed.
Removing accumulated liquid waste improves site access, provides a cleaner work area and allows contractors to carry out inspections, repairs or construction activities more efficiently. It also helps reduce delays caused by flooded or obstructed excavation areas.
