Because you need a high level of safety when excavating around buried or high-risk services, there is no better option than visual confirmation. The Hydro-Trailer is the perfect approach for water-blasting and hydro-excavating soils to visually confirm services. A built in 850lt pressure tank securely holds all spoil from the wide mouthed vacuum hose, meaning this can not only reach far and wide, but also remove a lot of debris for safe disposal.
