Vacuum Excavation (also referred to as Non Destructive Digging or Hydro Excavation) techniques are widely accepted as the safest way to expose or excavate around underground services, such as electrical and communication cables, water, gas, storm water and sewerage pipe work.

non-destructive method of digging (NDD) ensures minimal risk of damage to buried assets, compared to mechanical excavators which can easily damage existing underground services. NDD provides a risk free means of safely exposing underground cables and pipes which often run in different directions at various depths.
