Ultra-Rib Features and Benefits

Ultra-Rib offers the user a pipe having a seamless, uniform, cross-sectional wall; radial ribs which are perpendicular to the axis of the pipe; and a smooth interior for excellent flow characteristics. Ultra-Rib's design enables it to resist earth and impact loads normally associated with sewer and drain pipe installation. The outstanding chemical and corrosion resistance of Ultra-Rib, along with an integral bell and rubber gasket joint, make it an excellent choice for sanitary sewer systems and other drainage applications.
