In the construction field, our hydro and air excavators are mainly used to aspirate materials of all kinds both liquid and solid. They are used particularly when digging trenches and holes for poles (polarization) and for digging in hazardous or restricted environments. We propose two alternatives: hydro-excavation or air-excavation. Hydro-excavation is a digging technique from 3,000 PSI to 6,000 PSI, using water at ambient temperature or heated with a burner of more than 800,000 BTU. One of the strengths of our equipment is our insulated and heated cabs which allows us to work at temperatures -40oC. This technique is extremely efficient and fast, even in frozen ground. Air-excavation offers an air jet, without water. Thus, the collected material is dry and can be reused on site rather than having to be relayed to a deposit of liquid materials.
Air-excavation is generally used in less compact soil. A major asset to using air-excavation is that water supply is not required to perform the digging.
