Air-Knife Underground Clearing

Air knifing utilizes high-velocity air to penetrate, expand, and break up subsurface soil. The soil and rock is then removed from the hole using a powerful vacuum. The air knife method provides the advantages of safety (this method is far less likely to damage underground utilities than mechanical excavation) and speed. Typical Air Knife applications include:

  • Pre-drilling location clearance
  • Underground utility location verification
  • Cathodic protection installation
  • Underground piping and conduit repairs
  • Manway and valve box cleaning/maintenance
  • Rehabilitation/de-silting of small diameter wells
