Elliptical Reinforced Concrete Pipe

Elliptical reinforced concrete pipe manufactured by County Materials is a time-tested solution for storm water systems and diverse municipal applications. When design constraints call for shallow depths and high flow, engineers turn to elliptical reinforced concrete pipe. Most sizes available with pre-lubricated gaskets, providing a watertight joint that resists infiltration of silts and sands. Elliptical pipe’s enhanced joint security promotes ease and speed of installation, reducing time and labor costs.
