For over a century, engineers have specified Reinforced Concrete Pipe (RCP) for its speed and versatility advantage. A reliable solution for stormwater and sanitary applications manufactured in a factory-controlled environment. Concrete pipe is a rigid system and the pipe is the structure, whereas flexible materials can be flammable and depend almost entirely on installation and backfill material for building the structure, making proper installation nearly impossible. Concrete pipe is your proven, reliable solution. Available in multiple shapes and sizes including round, arch, cattle or stock underpass, and several variations of special fittings.
