How to Choose the Right Vac Truck
A Plain Sydney Hire Guide
The right truck depends on site access, spoil volume, dig depth and job type. Describe the job to Pro Expose and we will match the right truck to the work.
The Factors That Decide It
Most people call and ask for a vac truck without knowing which size. That is fine. The size is the answer, not the question. These are the five factors we use to work out which truck suits the job.
Capacity Classes at a Glance
Each capacity class suits a different combination of access and volume. Here is an honest summary of where each class fits best.
A Quick Checklist When You Call
The more of these you can give us, the faster we can match the right truck and quote the job. You do not need every answer. An approximate description is enough to get started.
- Access width to the dig zone (gate width, driveway width, any height or surface restrictions)
- Dig depth (approximate, even a rough range helps)
- Spoil volume estimate (number of holes, size of each, or square metres if known)
- Soil type if known (clay, sand, fill, rock, or unknown)
- Job type (potholing, service locating, drain work, civil excavation, other)
- Timing (target start date, how many days on site, any hard deadlines)
Vac Truck Selection FAQ
How do I know what size vac truck I need?
Tell us the access width to the dig zone, the estimated spoil volume, how deep the work is going, and whether it is potholing, drain work or broader civil excavation. Those four factors together determine the right size. A 500L micro suits tight access single-hole work; a 4500L covers most general residential and light commercial jobs; a 6000L or larger suits civil and high-volume commercial work with good access. If you describe the job we will match the truck.
Does a bigger vac truck always dig faster?
Not necessarily. A larger truck carries more spoil before needing a tip run, which helps on high-volume jobs. But if access to the site is tight, a bigger truck may have to set up further away and run longer hose back to the dig face, which can slow things down and reduce suction efficiency. The right truck is the one that can get closest to the work with enough tank capacity for the job.
What if my site has tight access?
Tight access is the most common reason to use a smaller-capacity truck. The 500L micro vac truck is suited to narrow side gates, basement entries, internal courtyards and heritage sites where a standard vac truck cannot reach the dig zone. Call 0438 498 274 with the gate or access width and we will tell you whether the truck can get in or whether a longer hose run from the street is the better option.
Is vac truck hire wet hire or dry hire?
All vac truck hire through Pro Expose is wet hire. That means the truck comes with an experienced operator, the water supply for the hydro excavation process, and spoil removal to an approved facility. You do not need to supply water, hire a separate operator, or organise tip runs. The operator runs the dig from setup to pack-down.
