Water-powered excavation that protects underground services.
Precision digging for residential, commercial and civil projects across greater Sydney.
Hydro excavation — also known as vacuum excavation — is a non-destructive digging technique that replaces mechanical excavators with pressurised water and industrial vacuum suction. Pro Expose provides vacuum excavation across Sydney for residential, commercial and civil projects. Rather than tearing into the ground with metal teeth and risking damage to buried infrastructure, hydro excavation uses a focused water jet to loosen soil one layer at a time. The loosened material is immediately extracted by a high-powered vacuum and collected in a sealed spoil tank mounted on the vac truck.
This two-stage process. water cutting followed by vacuum extraction. gives the operator complete control over the excavation. Soil is removed precisely where needed, leaving adjacent ground, tree roots and landscaping undisturbed. Underground services including gas mains, water pipes, electrical conduits, sewer lines and fibre optic cables are exposed without any physical contact from digging equipment.
In Sydney, hydro excavation has become the standard method for any digging work near live utilities. Councils, civil contractors, plumbers and electricians rely on it because it eliminates the most common cause of underground service damage. accidental strikes from mechanical buckets and hand tools. For homeowners, it means excavation work can happen in backyards and beside driveways without the destruction that comes with a traditional digger.
Pro Expose Hydro Vacs operates purpose-built compact vac trucks designed specifically for Sydney's tight residential and urban environments. Our equipment fits through side gates as narrow as 900mm, reaches over fences with extended vacuum hoses, and works quietly enough for suburban streets. Whether the job involves a single pothole to locate a gas line or a full trench for new plumbing, hydro excavation delivers the precision and safety that mechanical methods simply cannot match.
Pro Expose operates wet-hire hydro excavation trucks — both mini and full-size hydro vac trucks — as a vacuum excavation contractor across Greater Sydney, dispatched from our Merrylands base. A hydro vac truck pairs a high-pressure water jet with industrial vacuum suction to dig safely near live utilities, which is why plumbers, civil crews and councils book a hydro vac truck instead of a mechanical digger for any work around buried gas, water, power and telco services. As a vacuum excavation contractor we run non-destructive digging (NDD) on residential, commercial and civil sites, including tight-access jobs through 900mm side gates and 24/7 emergency callouts.
Choosing a vacuum excavation contractor with the right hydro vac truck for the job matters: the mini unit reaches backyards and laneways most trucks cannot, while the full-size truck handles high-volume civil spoil. Whichever truck suits the access, the same NDD method keeps underground services protected. For a full breakdown of hydro excavation cost, see our vac truck rates page.
Every year, mechanical excavators cause thousands of underground service strikes across Australia. Hydro excavation eliminates this risk entirely.
A mechanical excavator uses a steel bucket to rip through the ground. If a gas pipe, power cable or water main sits in the path of that bucket, the result is a service strike. potentially causing gas leaks, electrical hazards, water main bursts or internet outages for entire streets. Repair costs for a single service strike can run into tens of thousands of dollars, and the liability typically falls on the party who caused the damage.
Hydro excavation replaces that steel bucket with water. Because the digging medium is a pressurised stream rather than a rigid tool, it flows around pipes and cables instead of cutting through them. Even direct contact between the water jet and a buried service will not cause the catastrophic damage that a mechanical strike would. This is why hydro excavation is classified as non-destructive digging (NDD) and is now mandated on many civil and construction sites across NSW.
Beyond protecting utilities, hydro excavation also reduces property damage. There are no heavy machines driving over lawns, no excavator tracks cracking driveways, and no piles of dirt left on site. The spoil goes straight into the tank, and the work area is left clean. For residential properties in Sydney where gardens, paving and fences sit close to the dig zone, this matters.
From a single pothole to a full civil excavation program, hydro excavation covers a wide range of digging requirements across Sydney.
We built our business around one goal: safe, efficient excavation that arrives on time and leaves your site clean.
Pro Expose Hydro Vacs is a Sydney-based hydro excavation company specialising in tight access work. Our compact mini vac trucks are designed to access properties and sites that full-size vacuum trucks cannot reach. through narrow side gates, down tight driveways and into confined backyards. This makes us the go-to choice for residential hydro excavation across Sydney's inner suburbs, where space is always at a premium.
Every job is operated by experienced hydro vac technicians who understand Sydney's underground infrastructure. We review Dial Before You Dig plans before arriving on site, use electronic service locating equipment to verify asset positions, and excavate methodically to expose services without damage. Our track record speaks for itself: zero service strikes across completed residential and civil excavation jobs.
We quote upfront with no hidden fees. Our vac truck hire Sydney rates include the operator, equipment, water and spoil disposal. Whether you need a single pothole dug in 30 minutes or a full day of trenching across a construction site, you will know the cost before we start.

Common questions from Sydney homeowners, builders and contractors about hydro excavation.
Hydro excavation is a non-destructive digging method that uses a pressurised stream of water to break up soil and a powerful industrial vacuum to extract the loosened material into a spoil tank. The operator directs a water lance at the ground surface, which cuts through clay, sand and compacted fill without the mechanical force of a traditional excavator. Because no metal teeth or blades contact the ground, buried services such as gas pipes, electrical conduits, water mains and telecommunications cables remain completely protected.
Yes. Sydney soils range from heavy clay in Western Sydney to sandstone in the Eastern Suburbs and North Shore. Our hydro vac equipment operates at industrial water pressures that effectively cut through compacted clay, shale and sandy soils. For extremely hard ground, we adjust the pressure and flow rate to maintain efficient excavation while still protecting any underground services below.
Hydro excavation can reach depths of several metres depending on the job requirements. For standard potholing and service exposure, most excavations are between 0.5 and 2 metres deep. Our long-reach vacuum hoses and adjustable water lances allow us to work at greater depths when needed for civil or infrastructure projects. There is no practical depth limit for the water lance. the vacuum extraction range is what determines maximum working depth.
Yes, a Dial Before You Dig report is required before any excavation in NSW, including hydro excavation. The DBYD report identifies the approximate location of underground assets on your property. At Pro Expose, we review DBYD plans before every job and use our service locating equipment to verify asset positions on site before digging begins. If you do not have a DBYD report, we can guide you through the free online request process.
The soil-water mixture (called spoil or slurry) is vacuumed directly into the sealed spoil tank on our vac truck. Once the tank is full or the job is complete, we transport the spoil to a licensed disposal facility. This keeps your site clean with no piles of dirt left behind. Spoil disposal is included in our quoted price. there are no hidden tip fees.
Absolutely. Our compact mini vac truck is purpose-built for tight access work in Sydney. We regularly work through side gates as narrow as 900mm, in small backyards, courtyards, and between buildings. The vacuum hose can extend well beyond the truck position, so the vac truck does not need to be directly over the dig site. This makes hydro excavation ideal for inner-city terraces, established gardens and properties with narrow driveways.
A hydro vac truck combines a high-pressure water jet with a powerful industrial vacuum to break up and remove soil without striking buried utilities, which makes it the core tool of non-destructive digging. Pro Expose operates hydro vac trucks as wet hire across Sydney, dispatched from our Merrylands base, with the truck, operator and equipment supplied together so the unit arrives ready to work.
Pro Expose is a vacuum excavation contractor, not a dry plant hire company. We provide operated non-destructive digging (NDD), which means you book the excavation outcome rather than a bare machine to run yourself. All work is wet hire, with the truck and equipment supplied together and dispatched from Merrylands.
A hydro excavation truck combines a high-pressure water jet with industrial vacuum suction to break up soil and lift it into a sealed tank, so you can dig safely around live gas, water, power and telco services without a mechanical digger.
