How Does Vacuum Excavation Work?

Have you ever wondered how Vacuum Excavation works? Why continue with the stressful exercise of instructing your operatives to excavate around existing services with traditional methods of excavators and spades?

  • Place the remote-controlled boom over the area that requires excavation, around 6-8 inches above the material. Switch on the vacuum fans to start the suction process.
  • As the material starts to make its way up the suction pipe, follow the material with the boom ensuring the 6–8-inch gap is maintained to allow for constant air flow.
  • As the service becomes visible, the material gets harder, the use of an air lance may be required to loosen the ground or clear the service.
  • There is a selection of tools onboard to deal with different conditions i.e., reduced pipe size for narrow areas, air lance for loosening material and air breakers for breaking up the hard surface, all driven by a built-in compressor.
  • With our vast experience in the Civil Engineering sector, we offer advice on other equipment or materials that may be required to complete the task safely and can even assist with the temporary works.
  • To support projects, we can provide a full package i.e., supply ground protection with rubber mats or fence panels to fence off the work area.
  • The material is stored in a built-in skip that is capable of holding 8m3. To reduce transport costs, we take the excavated material to a stoke pile on site.
  • The material is dispensed by lifting the lid upright and side tipping the material to offload onto the ground. The material can also be tipped directly into demountable skips, ready for removal from site to avoid reloading.
  • Many contractors prefer the vacuum system when working in built-up areas to ensure safe excavation around existing services and to keep footpaths clear of material to prevent slips, trips and falls for the work force and general public. In addition, the noise level of the equipment is under the legal requirement.
  • To prevent any contamination in the air, the vacuum is created by air circulation where there is a filter system that consists of 42 filters. This ensures that there is no escape of dust.
