Hydro Vacuum Excavation occurs when high-pressure water breaks up and cuts the soil, while a high-flow vacuum system removes the soil up and out of the excavation area.

"Hydro Vacuum Excavation provides a non-destructive, non-evasive, cost-effective and accurate process to safely locate underground services prior to excavation."

There are numerous safety concerns that Hydro Vacuum Excavation addresses. Traditional mechanical excavation has the potential to damage utilities and disrupt essential services. Utility damages occur for many reasons including operator error, mismarked or unmarked surface locations, the unknown presence of multiple lines found below a single surface mark, and occasionally, the obvious negligence of proper construction procedures.

With Provac Australia Pty Ltd Hydro Vacuum Excavation virtually eliminates damage to the underground service and potential personal injury, which sometimes occurs through the use of heavy equipment or laborious hand trenching. Hydro Vacuum Excavation can be performed in all weather conditions.

Operators can dig with precision, establishing a less invasive method for slot trenching, potholing, and pipe location. This manner of excavation causes less surface damage reduces disruption of traffic and other surface activities and can be easier and less expensive to repair.

Hydro Vacuum Excavation uses pressurized water to break up soil that is then removed through a vacuum system and deposited into a debris holding tank, to be disposed of at the end of the job. The system removes ALL waste and leaves a nice clean hole/trench with no unsightly mounds of dirt or messy construction site looking leftovers.

The many benefits of Hydro Vacuum Excavation over traditional utility locating:

Safety
It reduces the risk of personal injury and death from hits and strikes of service cabling (power for example).

Damage Prevention
It assists in avoiding the tremendous financial liabilities, inconvenience to service users, and company embarrassment of damage done to underground cabling / infrastructure.

Adaptability
Hydro Vacuum Excavation is a cost-effective solution to excavate services in highly congested building or traffic areas, in any weather condition.

Functionality
Hydro Vacuum Excavation can also be used to uncover pipelines, phone lines and fiber optics, to excavate for signs and signals, and clean and remove debris from manholes, concrete basins, culverts and conduits.

Hydro Vacuum Excavation has many versatile uses including:

• Culvert and Drain Cleanout
• Potholing of Services
• Sign and Pole Installation(including power poles)
• Culverts and Cattle Guards
• Slot Trenching
• Underground Line Exposing
• Installing New Underground Facilities
• Digging Under Existing Structures
• Trenching across conflicting services
• Material / Debris Removal
• Pipeline Tie-ins/Maintenance
• Sludge Removal
• Extraction of Wet and Dry Materials
• Pit & Conduit Cleaning
