Vacuum Excavator

Product Overview

A Vacuum Excavator, also known as a Hydro Excavator or Vacuum Excavation Truck, is a specialized excavation machine that uses high-pressure water or compressed air to loosen soil and a powerful vacuum system to remove the loosened material into a debris/spoils tank. This process is commonly called soft excavation or non-destructive excavation.

The equipment is particularly useful where underground utilities, pipelines, cables or other buried infrastructure must be exposed with greater control than conventional mechanical excavation.
