Non- Intrusive Digging: Proven Cheaper and Safer at Enabling Access to Buried Services

Non- Intrusive Digging: Proven Cheaper and Safer at Enabling Access to Buried ServicesNon-intrusive digging, also known as potholing, vacuum excavation or non-destructive digging is a particularly safe, efficient and environmentally sustainable method of excavation. This method, utilised by Veolia Environmental Services is used to uncover buried services like pipes and electrical cables as well as planting posts and power poles.

Non-intrusive digging uses a highly controlled, variable pressure stream of water of up to 2,000 psi to break-up ground and soils, but does not hold enough force to damage pipes and cables. These soils are then removed by a high volume vacuum system to expose underground services and structures.

VES has used this excavation method across Western Australia , allowing it to gain popularity over conventional alternatives, largely due to to non-intrusive digging:

  • Providing a clean and precise method of excavation, as it involves less material to remove, thus making it faster and cheaper than machine extraction,
  • Reducing accidental line damage, sometimes enabling services to be located whilst online and consequently not requiring shutdown, loss of production or other inconveniences,
  • Reducing damage risk to line casings and pipe coatings,
  • Hoses can reach into areas whereas large excavators cannot,
  • Reducing the risk of the caving in of trenches; and
  • Performing major excavations in difficult areas for instance, backyard swimming pools etc.
