Vacuum excavation

What is vacuum excavating
Also known as non-destructive digging (NDD) or soft digging

The vacuum excavation process utilises powerful air suction to remove loose materials, and convey to a holding tank. Where materials are hard packed and bound together a high pressure water lance is used to breaking up and loosening materials around the target area. Holding tank spoils can be removed and taken to a suitable waste disposal site or stock piled on site for reuse.

Hydro vacuum excavators come in various sizes depending on the required task they share the same basic mechanical process. Below are few of the main mechanical components and their basic function

  • Hose – Flexible hose conveys the materials
  • Tank – the spoils tank holds the captured materials
  • Filtration – cyclonic separator and fine filters remove small particulars
  • Blower pump – positive displacement blowers pump large volumes of air with powerful suction
  • Motor – to drive blower and accessories
  • Water pressure pump – provides high pressure water to lance for material break up
