Hydro excavation is a method of breaking up and removing soil using a high-pressure water jet. The loosened material is then vacuumed away as a slurry and held in the truck's spoil tank for disposal at an approved facility. Because it uses water rather than mechanical teeth or buckets, it reduces strike risk to buried services compared to mechanical digging and leaves the surrounding ground largely undisturbed.
A vac truck is a vacuum excavation unit that combines a high-pressure water supply and a powerful industrial vacuum on one vehicle. The operator directs the water lance to break up soil at the dig zone. The vacuum hose draws the resulting slurry into the onboard spoil tank. At the end of the job the spoil is taken to an approved disposal facility. The truck carries its own water supply so there is no need for an external tap on site.
Non-destructive digging (NDD) is the practice of excavating around buried infrastructure without using mechanical equipment that could cut or crush services. Hydro excavation is the most common NDD method. It is used by civil contractors, councils, utilities and builders when excavating near gas, water, electrical, telecommunications or sewer lines where a mechanical strike would be costly or dangerous.
Potholing is the process of digging small test holes to physically confirm the position, depth and condition of a buried service before excavation proceeds. It is commonly used ahead of trenching, pile drilling or civil works to verify that plans are accurate and that services are where drawings say they are. The holes are typically small in diameter, targeted at a specific service crossing point, and backfilled once the information has been recorded.
Pro Expose operates a compact tight-access vac truck and matches the right truck to the job. Options range from a 500L micro unit suited to ultra-tight residential access through to mid-size and larger capacity trucks for civil and commercial work with higher spoil volumes. See our guide on how to choose the right vac truck, or call 0438 498 274 and describe the site and scope and we will advise which truck is the right fit.
Yes. Tight access is one of the most common reasons clients call us. The 500L micro vac truck is designed for sites where a standard truck cannot physically reach the dig zone, including narrow side gates, residential driveways, basement entries, internal courtyards and heritage properties. Where the truck cannot get close, longer hose runs allow the machine to stay on the street while the lance and vacuum hose reach the dig face.
Achievable depth depends on soil type, water table, the moisture content of the material and the access and working space available on site. Most service location and potholing work falls in the shallow to mid-depth range. For deeper civil excavation, the larger the truck and spoil capacity, the more efficiently the work can be done. Describe the job and likely service depths when you call and we will advise the right approach.

All vac truck hire from Pro Expose is wet hire. That means the truck, an experienced operator who runs the machine from setup to pack-down, the water supply for the hydro excavation process, and spoil removal to an approved disposal facility. You do not need to supply water, organise tip runs or provide your own equipment. The operator manages the full dig.
Pricing depends on the job size, the duration of the hire, the truck required, the volume of spoil to be removed and site-specific factors such as access difficulty. We provide upfront quotes before work begins so there are no surprises. Call 0438 498 274 or send us the job details through the contact page and we will turn around a quote promptly.
Yes. We work across a range of engagement lengths, from a half-day potholing job through to single-day and multi-day residential or civil projects. For ongoing or programme work, call 0438 498 274 to discuss scheduling and how to fit the right truck to each stage of the work.
Public liability and workers compensation insurance is held. If your site or principal contractor requires evidence of insurance, call 0438 498 274 or email [email protected] and we can provide certificates of currency.
Yes. We work to current Before You Dig Australia (BYDA) processes as part of our pre-dig planning. BYDA provides plans showing the likely location of underground utility infrastructure so that operators can plan the dig safely and identify any services that need specific precautions. This is standard practice for NDD and hydro excavation work in NSW.
