The ZhongYi polymer concrete trench drain system is well suited to a wide variety of surface drainage applications.The ZhongYi polymer concrete trench drain system has lower installed cost when compared to conventional hand-formed cast-in-place methods of creating trench drains.

ZhongYi polymer concrete trench drain components have superior chemical resistance, greater strength, lower water absorption, and better freeze/thaw resistance, Polymer concrete is not degraded by salt, oil, most acids and alkalis, and offers UV resistance.These polymer concrete properties make ZhongYi trench drains excellent for capturing, containing, and transporting surface runoff in any drainage application.

By virtue of a smooth interior finish, radius bottom, and built-in 0.6% slope, flow velocities of 1 meter/second (3.5 feet/second) are attained inside ZhongYi trench drain channels even in flat grade conditions.The higher hydraulic flow velocity and smooth surface reduces debris build-up in the polymer concrete drain channels in comparison to cast-in-place trench drain construction.
