Safe and Precise Excavation With Vac-Ex

Vac-Ex is a non-intrusive method of excavation that uses compressed air to loosen up the ground, followed by suction to remove the loose material. A Vac-Ex machine can generate a powerful stream of air with an operator controlling the intake nozzle, providing full control of the excavation while they remain at a safe distance. This method significantly reduces spoil and dust because all of the extracted material is sucked directly into sealed collection chambers on the machine, making it particularly suitable for use in confined spaces.

Vac-Ex machines have a wide range of applications across UK construction projects, including:

  • Excavating trial areas and pits as small as 20cm to confirm if services are present.
  • Providing excavation solutions in potential high-risk areas.
  • Providing a safe and efficient excavation solution where services are known to be present
  • Vac-Ex machines can be utilised at the design stage of a project alongside PAS 128 surveys to plot out existing services
  • Smaller AIR-VAC units allow us to access areas conventional excavation and Vac Ex equipment are unable to.
  • We can use our smaller Vac Ex machines alongside Brokk machinery to offer a fully remote service to potentially hazardous work areas

By using Vac-Ex machines, construction projects can ensure that all works are conducted safely, efficiently and without causing any disruption to normal operations.

Our wealth of Vac-Ex experience

When a large housing developer approached us with the challenge of locating a 6-inch gas main on a new construction site, we saw an opportunity to showcase the capabilities of our new Vac-Ex AIR-VAC unit. With its compact size and advanced technology, our mini-tracked excavator swiftly and accurately excavated a 35-meter trench, allowing us to determine the location of the gas main without any service disruptions. This efficient solution saved time and money for our client while minimizing environmental impact.
