As an industry leader in hydro excavations, cable locations and all underground service locating, the demand for our services have seen us expand into Melbourne and the wider Victorian market place.
With today’s stringent safety procedures, rules and regulations our vacuum excavations are a fool-proof way of getting the job done quickly, efficiently and without damage to any underground services.
Provac will ensure that you won’t damage or destroy any underground services whilst digging.
Vacuum excavations, also known as hydro excavations, is a form of non-destructive digging (NDD). This type of excavation is fast becoming the most popular method of excavation, when carrying out work in the vicinity of any underground assets.
Vacuum excavation uses keyhole technology to identify underground services and minimises the risk of damage to even the thinnest underground cables. The process starts with high-pressure water being applied to the soil to break it down.
The soil is then excavated via a vacuum hose and is collected in our vacuum tank, eliminating any need for further clean ups, keeping the site both tidy and safe. Hydro excavation work using a vacuum excavation truck has proved to cause the least amount of inconvenience to the public, and greatly reduces the risk of any inconveniences.
Utility damage was quite common in the past and the inconvenience caused to both the asset owners and your company can be costly.
Not only do you need to consider your liability, you also need to consider the down-time needed for the repairs to be undertaken, both can end up blowing out your project budget.
The benefits of vacuum excavation services are ten-fold. Not leaving yourself vulnerable to potential issues due to so many underground assets beneath the surface in Melbourne and greater Victoria during your construction project is worth the peace of mind alone.

Hydro Vacuum Excavation uses pressurised water to break up the earth’s surface and soil which is then removed through a vacuum system and deposited into a debris holding tank to be disposed of at the end of the job.
At Provac Australia we have a selection of Vac truck sizes 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 services are present within a job site dig area. It is your duty of care and responsibility to follow the appropriate steps of action to identify that there may or may not be underground services within your dig area.
Depending on the scopes of the job 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 as opposed to digging in and through a rocky subsurface.
Our Vac trucks are all equipped with suction hose and gerni wand extensions. All of our trucks carry a minimum of 20m of extension hose but can carry up towards 60m of extension hose on board. Our gerni wands can be adjusted from 1.5m in length up to 3.0m in length.
Depending on the type of ground that you are digging in, A vac truck 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 operators safety.
Yes. Our services are often called upon by Electricians and Plumbers who are wishing to install new pipes and cables. We have dug trenches for some of our electrical clients that have been 1m deep and up to 80-100m long.
