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.
