Treatment Plants


  • Provides structural integrity
  • Improves flow by reducing the roughness coefficient
  • Resistance to the adverse effects of sewage
  • Repair without interference with existing utilities
  • Maintains flow in line while rehabilitation is accomplished
  • Minimum disruption of traffic

SHOTCRETE (wet mix or dry mix) is a mixture of sand, cement, and water. Dry mix is applied through a rubber hose from a cement gun. The materials are mixed in a relatively dry state and are hydrated at the nozzle in a special mixing nozzle.

Hydration begins as the material leaves the chamber and the resulting mixture is shot into place under air pressure.

The pressure application permits shotcrete to be applied to practically any surface at any angle and at a specified thickness.

When properly mixed and applied, Shotcrete has a wider range of applications and is less expensive than concrete that is applied by any other method. It is extremely strong, dense and is highly resistant to weathering and many forms of chemical attack. The ease and speed at which the material can be applied has resulted in the method's ever-increasing use.
