Hydro Vacuum Excavation services is a non-destructive digging (NDD), non-evasive, cost-effective and accurate process to excavate safely. It is now often far more cost-effective to complete your excavation requirements utilising vacuum hydro excavators. Our complete range of professional hydro excavation services is offered right throughout the Gold Coast, Brisbane, South East Queensland and beyond.
Hydro vacuum excavation uses high-pressure water to break up and cut the soil, gravel and rock, while a high-flow vacuum system removes the debris up and out of the excavation area. This process offers maximum safety and protection to your critical assets.
Unlike traditional mechanical excavation using bobcats, backhoes, or bulldozers, hydro vacuum excavation minimises the chances of damaging or disrupting essential underground services. Damage to utility lines can occur for many reasons including operator error, mismarked or unmarked service locations, the unknown presence of multiple lines found below a single service, and occasionally the obvious negligence of proper construction procedures.

Our vac trucks use pressurised water to break up soil which is then removed through a vacuum system and deposited into a debris holding tank to be safely disposed of.
At Provac we have a selection of vac trucks ranging from as little as 1000L trailer-mounted units to as big as 12,000L truck-mounted units. Our most commonly used truck size ranges between 5,000L – 8,000L units.
Digging safely with a vac truck is highly recommended when underground utility services are present within the area of digging. If you're unsure what lays underneath the ground, you should always call Provac to locate and map the area out.
Depending on the job's scopes, it can sometimes be quicker, easier and safer to use a Vac truck to excavate. The type of ground can also affect the time it takes to dig with a vac truck. For example, it can be much quicker to dig in and trough sand instead of digging in and through a rocky subsurface.
Our Vac trucks are all equipped with a suction hose and gerni wand extensions. All of our trucks carry a minimum of 20m of extension hose but can carry up to a 60m of hose extension on board. Our gerni wands can be adjusted from 1.5m in length up to 3.0m.
Depending on the type of ground you are digging in, one of our vac trucks can typically dig up to 3.5m deep. On some projects, our vac trucks are used to dig in holes that have been mechanically excavated and properly shored and benched for our operator's safety.
