Air Knifing

Air Knifing PhotoSimilar 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 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 produces 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
