WHAT IS VACUUM EXCAVATION?


Vacuum Excavation is a non-contact and non-distructive method of removing soil.  It is widely used when digging in and around areas that can be damaged with traditional excavation means or when mechanical excavation is dangerous. Strikes to electricity, gas pipes and data cables ect are eliminated due to its unique soil removal process.

The process
  • High pressure low flow water is pumped from the water tank (blue) to the excavation head.
  • The water slurrifys the earth and is removed by the vacuum hose (black)
  • The removed spoils travel from the vacuum hose and is deposited in the tank for removal.
  • The vacuum pressure air is filtered, compressed by the vacuum pump and exhausted to atmosphere

As well as been non-destructive our process has a very unique property in that it can excavate very narrow and deep holes or trenches - 2 meters deep by 90mm wide is easily achievable.  The soil removal process is very rapid and can save between 4 - 5 times the time taken over hand dig.  Due to less soil been removed, less backfill been needed and smaller reinstatements required the cost saving when compared to hand dig are very significant

Applications include:

  • Tree Root excavation
  • Underpinning excavation
  • Pot holing and trial trenches
  • Tank Cleaning
  • Storm Drain Clean out
  • Exploratory excavation
  • Cellar excavation
  • Trenching
