Similar to hydro-excavation (without the water), air knifing utilizes high velocity air to penetrate, expand, and break up soil. The soil is then removed from the area using a powerful vacuum. Air knifing (aka potholing or daylighting) includes all of the advantages of hydro-excavation. In addition, air knifing results in dry soil waste, which typically reduces disposal costs compared to the slurry produced through hydro-excavation.

Typical air knife applications Include:

  • Surgical excavation around known or suspected utilities
  • Pre-drilling location clearance
  • Underground utility location verification
  • Underground piping and conduit repairs
  • Rehabilitation/desilting of small diameter injection wells
