PolyDrain trench drains have gained dramatically in acceptance and usage over the years by addressing a wide variety of surface drainage applications. The PolyDrain Forming System provides design flexibility, greater construction accuracy, less installation labor and skill, and has lower installed cost when compared to conventional hand formed cast-in-place methods of creating trench drain.

PolyDrain's polymer concrete components have superior chemical resistance, greater strength, lower water absorption, and better freeze/thaw properties than does Portland cement concrete. Polymer Concrete is resistant to salt, oil, most acids and alkalis, and offers UV resistance. These features make it excellent for capturing, containing, and transporting surface runoff in any application.

The standard Polydrain system comes in 1 meter long sections with 100mm (4 inch) wide openings. Polydrain contains both pre-sloped and non-sloped channels, grates and frames, catch basins, end plates, installation aids, and all other components to provide a complete system drainage solution.

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

The PolyDrain Line also contains Special Products for other non-sloping systems. These products lines are optimized for containment applications, utility trenches, limited space installations, and for greater hydraulic flows in sloped site.
