Hydro Excavation
What Is Hydro Excavation?
Hydro excavation is a method of digging that uses pressurised water to break up soil and a powerful vacuum to lift the loosened material out of the hole. Because nothing hard strikes the ground, pipes, cables and other buried services can be uncovered without being hit.
It is also known as vacuum excavation or non-destructive digging. The result is a clean, accurately sized hole or trench, with the spoil collected by the vacuum rather than piled beside the dig.
Drain Vac uses hydro excavation alongside its drain and plumbing work, so the same team can expose a pipe, clear it and help you plan what comes next.
Common Uses
What Is Hydro Excavation Used For?
Hydro excavation is used for any dig where accuracy matters or where something underground must not be damaged. These are the most common jobs around Warrnambool.
Trenching Near Existing Services
Opening narrow trenches for new pipes or conduits where existing services run close by.
Exposing Drains and Pipes
Uncovering a stormwater or sewer pipe so a blockage or fault can be reached.
Post Holes and Footings
Digging clean holes for posts, signs and small footings, especially near services or in tight spaces.
Digging Around Tree Roots
Removing soil from around roots with far less damage than a machine bucket would cause.
Tight and Restricted Access
Working in narrow side paths, under structures and in places a digger cannot reach.
If there is any chance of services under the ground, find out before anyone starts digging.
Why Hydro Excavation
Why Choose Hydro Excavation Over a Digger?
Hydro excavation is chosen over a digger when damaging an underground service would be costly or dangerous. A machine bucket can cut through a water main, gas line or power cable in a moment, while water and vacuum expose the service so it can be seen first.
It is also more precise. The hole is only as big as it needs to be, surrounding paving and landscaping are disturbed less, and the work can go on close to footings, fences and trees.
In Warrnambool's sandy coastal ground and soft river flats, where trench walls can be unstable, a narrow and controlled excavation can also be easier to manage than a wide machine dig.
Hydro excavation suits sites with:
- Known or suspected underground services
- Limited access for machinery
- Paving, lawns or gardens to protect
- Work close to footings and trees
- Soft, sandy or wet ground
Hydro excavation exposes services. Any repair or connection work that follows is planned as a separate step.
Before You Dig
How Do You Prepare for Hydro Excavation?
Preparing for hydro excavation starts with finding out what may be under the ground. A Before You Dig Australia enquiry lists the asset owners in the area, and any plans you hold for the property help narrow down where services run.
It also helps to mark out the area to be dug, clear vehicles and materials from the work zone, and let Drain Vac know about access, gates and anything else on site that could affect the job.
Useful to have ready:
- Before You Dig Australia plans
- Site plans or drainage drawings
- The marked out dig area
- Clear access for the work
- A contact person for the site
Is Hydro Excavation Messy?
Hydro excavation is usually tidier than people expect. The loosened soil is lifted straight out by vacuum, so there is no spoil heap beside the hole and less mud spread across the site.
The excavation itself is neat and close to the size needed, which means less reinstatement of lawns, paving and gardens afterwards.
Can Hydro Excavation Be Done in Winter?
Hydro excavation can be done through a Warrnambool winter, because the method already works with water and wet ground. Very heavy rain or flooding can still affect access and timing.
Soft, waterlogged soil is often where a machine dig struggles most, so a controlled water and vacuum excavation can suit winter work well.

How Does Hydro Excavation Help With Drain Problems?
Hydro excavation helps with drain problems by exposing the exact section of pipe that needs attention, once a CCTV drain camera inspection has shown where the fault is. That keeps the dig small and focused rather than opening up a whole run.

How much does hydro excavation cost?
The cost depends on the size and depth of the excavation, the ground conditions, access and how long the job takes. Call 0474 868 388 or send the details through the contact page for a quote.
Do I need a Before You Dig Australia enquiry first?
It is strongly recommended before any excavation. A Before You Dig Australia enquiry is free and tells you which asset owners have services in the area, so the dig can be planned around them.
Is hydro excavation used near gas and power lines?
Yes. It is widely used near gas and power lines because it exposes them without striking them. Asset owner requirements still apply, so share any plans or conditions you have been given when you book.
Can hydro excavation find a blocked drain?
Hydro excavation exposes a drain once its location is known. A CCTV drain camera inspection is usually done first to find the blockage or fault, and then only that section is dug.
Does hydro excavation damage lawns and paving?
It disturbs far less than a machine dig, because the hole is only as large as it needs to be. Paving still has to be lifted where the dig passes through it, and lawns and gardens need reinstating as with any excavation.
Do you work for builders and plumbers?
Yes. Drain Vac takes hydro excavation work from builders, plumbers and other trades, as well as home owners, businesses and farms.
