History

Concrete pipe has a rich history, spawning an industry that today produces an economical, high quality product for numerous applications. It's been in use for over 5,000 years. In North America, concrete pipe has been used extensively in drainage and sanitary sewer systems since the 19th century.

Product Performance

The performance requirements of each pipe joint are generally determined by the function of the pipeline. Whether the purpose is to convey sanitary sewage or stormwater, joints are designed so that when sections are laid together they will make a continuous line of pipe with an interior free from irregularities. Joints can be designed to provide soil-tightness or water tightness, with the ability to accommodate deflection or longitudinal movement, and strength to handle shear or vertical movement.

Concrete pipe and precast products must efficiently convey the fluid for which they are designed. Secondly, they are structures, and must be able to support the weight of the earth, as well as live loads above it. Unlike alternate products, concrete pipe accomplishes both functions through its inherent strength and rigidity.
