Vacuum Excavation
Industrial vacuum excavation for safe, efficient exposure and removal of material.
Vacuum excavation uses powerful suction, with or without pressurised water or air, to lift soil, slurry and material from an excavation. It is a fast, controlled way to expose services, clear pits and recover material on active worksites.
What is vacuum excavation?
Vacuum excavation removes soil, slurry and debris from an excavation by suction rather than with a bucket. It covers both water-assisted and air-assisted methods, and is used to expose services, clear pits and recover material on active worksites.
Where this service is used

Benefits of using Dynamic
Fast material removal
High-capacity vacuum lifts soil and slurry quickly, keeping civil programmes moving.
Precise and controlled
Suction excavation exposes assets cleanly in congested corridors.
Scales with the project
Single units for spot works or multiple trucks for sustained programmes.
Relevant equipment

Safety considerations
- Reduces the need for personnel to enter excavations by hand
- Controlled material removal near live services
- Operators trained in vacuum unit operation and site controls
Where we deliver vacuum excavation
Vacuum Excavation is delivered by our regional teams along the Queensland and New South Wales coast. Choose a region for its serviced areas, local coverage notes and the way work is scheduled there.
Frequently asked questions
How is vacuum excavation different from hydro excavation?+
Hydro excavation always uses pressurised water to break up soil before it is vacuumed away. Vacuum excavation is the broader method of removing material by suction, which may use water or air. In practice Dynamic combines both to suit the ground and the task.
Can vacuum excavation recover wet and dry material?+
Yes. The fleet handles wet slurry and drier spoil, and units can be matched to the material and volume expected on site.
Is a vac truck the same as a vacuum excavation truck?+
Yes. Vac truck is the everyday name for the same equipment: a truck-mounted vacuum unit that lifts soil, slurry and debris into an onboard tank. On Dynamic units the same truck is used for hydro excavation and for material recovery.
What equipment suits a site with restricted access?+
Long hose runs let a unit stay on the street or hardstand and work in at a distance, which covers most confined, offset and internal locations. Where a truck cannot get close enough at all, a smaller unit is specified instead, so access is one of the first things confirmed when the work is scoped.

Hydro excavation as a risk control on civil construction sites
On a civil site the excavation method is a programme decision as much as a safety one. Hydro excavation is specified because it narrows the range of things that can go wrong at the point where a project is most exposed.

Hydro excavation compared with vacuum excavation
The two terms are often used as though they mean the same thing. In practice vacuum excavation describes the removal method and hydro excavation describes the cutting medium. Understanding the difference makes it easier to specify the right unit.
