Suction Excavation

Suction Excavation & Vacuum Extraction

A suction/vacuum excavator is a construction vehicle (Vac Truck) that removes debris below or above ground, via powerful suction of high-volume air flow, through a wide suction pipe which is up to a foot in diameter. This allows material to be excavated safely and effectively with low risk. Suction/vacuum excavation can be used for excavation of contaminated ground, water treatment, materials buried around utilities or services (railway lines, sub stations, gas, electric, water, fiber-optics, telecoms) and vacuum extraction for event clearance.

Suction/vacuum excavation is considered best practice for safely finding and seeing underground utilities, reducing damage by half to buried utilities.

How Suction/Vacuum Excavation Works

  1. The vacuum-excavator create air flow from the vehicle fans, using 40,000 m3/hr of air
  2. The vacuum pulls material into the intake hose and into the vehicles catchment chamber
  3. The material is then deposited in the holding tank and all dust particles are captured in a micromesh filter system

Possible Applications

  • Safe excavation around buried pipelines and cable networks
  • Emergency repair service for all pipeline and utilities network
  • Rail track maintenance or repair online or trackside
  • Deep Excavation and confined spaces
  • Culvert clearing
  • Water treatment filter bed clearance
  • Sewer clearance
  • Contaminated ground clearance
  • Clearing around tree roots
  • Basement work
  • Industrial application e.g. refineries, electric sub-stations, chemical plants
  • Long distance work can be catered for up to approximately 50 meters. Vertically or 150 meters plus horizontally (depending on conditions)
