Aluminized Steel Type 2 ULTRA FLO was chosen to reline an aging culvert in Evergreen, CO, due to its exceptional flow characteristics, structural integrity and ease of installation. Because of the ease of installation, the process was very quick, resulting in no road closures, which greatly benefited the community. The space between the new and existing pipe was grouted with flowable fill.

Contech ULTRA FLO Pipe has over a decade of proven performance on municipal, transportation, airport, shopping center and residential development storm sewer projects. ULTRA FLO’s rapid acceptance is based on its Manning’s “n” of 0.012, structural strength, and faster and more cost-effective installation than concrete pipe. ULTRA FLO is available in a wide variety of materials to meet environmental and service life requirements.
