Air Knife, Hydrovac and Vacuum Excavation Services

O6 Environmental air knife and hydrovac services provide essential support for industrial remediation projects at sites with delicate underground structures.

Safe, precise, and non-destructive, these innovative technologies penetrate, expand, and break up contaminated soil so it can be safely excavated for removal or treatment, without sedimentary layers or disturbing utilities buried nearby.

The targeted, surgical applications offered by these versatile and powerful tools benefit companies in a broad range of civic and commercial sectors, including:

  • Utilities
  • Oil and Gas
  • Construction
  • Telecommunications
  • Infrastructure Development
  • Transportation and Railroads
  • Municipal, County, and State Governments

Air Knife Excavation

An air knife creates an uninterrupted sheet of controlled, high-impact air, with enough velocity to remove dirt and debris without mechanical contact. The specially designed nozzle creates a laminar air flow which disrupts contaminated soil in a clean, controlled manner.

Any structures uncovered during excavation, such as storage tanks and utility lines, can be quickly cleaned with the same tool, in order to remove pollutants from sensitive equipment without compromising their integrity. Air knives quickly shear away dry debris, such as dust, dirt, sand, clay, and mineral buildup. The focused, pressured airflow is ideally suited to cleaning holes, crevices, and irregular objects.

During excavation, air knives work in tandem with a vacuum system, which collects the soil loosened by the compressed air ‒ avoiding the need for shovels, earthmovers, or other intrusive equipment. Besides avoiding accidental line damage, air knives also minimize the risk of trench cave-ins. Instead of climbing down into the excavation, workers can remain safe on the surface while cleaning and suctioning dirt from buried objects.

Hydrovac Excavation

Hydrovacs use high-pressure water to cut through and liquify soil, as well as to remove hard surface deposits from underground structures. Rather than rely on manual labor or heavy machinery, with their potential for accidents and damage, hydrovacs soften the ground with a concentrated stream of water that turns the targeted soil into a slurry before being suctioned up by a high-capacity vacuum. The captured material is then either stabilized and used as backfill or taken off-site for treatment and disposal.

By clearing dirt from and around buried equipment, hydrovac excavation allows you to uncover pipes and utility lines and extract hazardous material without the risk of breaks or tears. It’s indispensable in urban settings, where it can be used in place of conventional digging tools to pinpoint underground infrastructure with greater speed, accuracy, and safety.
