Ever been stuck in traffic because of roadworks, watching a crew painstakingly dig up the street? Chances are, they could have done it better and faster with a vacuum excavation truck.

We pride ourselves on revolutionising excavation methods. With decades of expertise and a relentless focus on innovation, customer service, and solving headaches for your business.

This comprehensive guide unpacks everything you need to know about vacuum excavation trucks

How do vacuum excavation trucks work?

Unlike traditional methods that use mechanical digging, vacuum excavation trucks use high-end vacuum technology to remove soil and debris through suction, leaving a clear, defined excavation space without damaging underground assets.

What are the benefits of using vacuum excavation trucks?

As well as this method being non-destructive to underground assets such as optic fibre wiring or pipes, vacuum excavation trucks eliminate the need for a separate excavator and dump truck, resulting in smaller space requirements, less servicing, and long-term savings overall.

What types of materials can be effectively excavated using vacuum excavation trucks?

From sand and clay to hazardous substances, vacuum excavation trucks handle all types of ground comfortably. In Australia and New Zealand, our high-productivity Cappellotto units—available with up to an 8" hose size—are a game-changer.

Note: If hazardous or dangerous goods material are involved, specialised trucks equipped to safely handle such substances may be needed, consult with one of the specialists at KOR to ensure you choose a truck that meets your operational requirements.

Are vacuum excavation trucks worth It?

Whilst they may require an initial investment, long-term vacuum excavation trucks can generate massive savings in time and money due to their efficiency. Because they’re a single truck operation the speed of set-up, operation and removal is often faster than traditional excavation. Plus they require no final clean-up as the material is removed as it’s excavated.

What safety measures should operators take when using vacuum excavation trucks?

The general objectives of the various Workplace / Occupational Health & Safety Laws across Australian States and Territories is to protect the health and safety of those in a workplace, manage risk and prevent risk to health.

Each jurisdiction has also a wide range duty placed on various parties to, as far as is reasonably practicable, provide and maintain a working environment that is safe and without risks to health.

This also includes providing such information, instruction, training, or supervision necessary to enable the performance of work that is safe & without risk to health.

It is recommended all involved in these activities are fully aware of their duties and responsibilities in each jurisdiction and avail themselves of the information readily available through their employers, associations, regulators, and suppliers.

  • Section 7.3 Training Class B
  • 7.3.2 Training Organizations

All operators shall be appropriately trained and assessed as competent.

Training shall be delivered through a Registered Training Organization (RTO) based on high-pressure water jetting units.

Are there any regulations or permits required for operating vacuum excavation trucks in urban areas?

In urban settings, certain rules must be observed to ensure smooth operation. Typically, the asset owner will provide guidelines on what's required to proceed. Always consult the asset owner or local authorities before starting any excavation work.

What are the different sizes and capacities available for vacuum excavation trucks?

Our fleet of vacuum excavation trucks spans a wide range, from 1,000 to 26,000 litres. The ideal size varies depending on the application. For personalised advice on what suits your project best, feel free to speak with a KOR representative.

Are there any limitations or restrictions on the depth that vacuum excavation trucks can reach?

While these trucks can reach astounding depths of up to 60 metres below ground, specific methodologies are required for deep vacuum excavations. If you intend to excavate this deep it’s important you consult an expert at KOR to ensure your chosen truck meets the requirements.

What maintenance and servicing requirements are necessary to keep vacuum excavation trucks in optimal condition?

To keep your vacuum excavation truck running like a dream, Regular servicing at six-month intervals for the chassis and three-month intervals for the body is recommended. Essential daily, weekly, and monthly checks are also necessary to ensure safety and performance.
