Hydrovac excavation refers to the process where soil is removed or displaced from one area to another by the use of pressurized water and a vacuum truck or vac truck. This involves the use of a large vac truck that uses suction to manage and holds debris in tanks. This method of digging is especially efficient where traditional mechanical excavation methods feasible. With Canada’s cold weather – warm water can easily push through the iced soil. Traditional mechanical excavation methods such as mechanical can be impeded with icy conditions, making hydrovac solutions useful for a large amount of applications.
