Starting in 2007 Stack Bros added the ability to provide Vactor HXX hydro excavator service to all its customers. Hydro excavation uses a truck mounted heated, high pressure water and vacuum system to cut through any type of ground from gravels to clay including frozen ground to provide year round excavation. This is especially effective when working around utilities like buried cable and pipelines. The vacuum service has grown to include a fleet of 9 hydro excavators and 3 additional vacuum trucks with the ability to vacuum dry products, providing complete vacuum and excavation options. With rail mounted Hydro excavators that make it possible to run the trucks down rail tracks to provide site specific work for needs for switch maintenance and spill response.
