POLYCAST optimizes three key factors affecting drainage: slope, drain design and interior finish. The result is drainage so superior that Polycast can be used in lieu of lager poured-in-place systems.
Polycast is available in convenient 4-foot sections and 2-foot half sections, each with a build-in 0.65 percent slope to affect full drainage.
With the proper components, flow rates of 470 GPM per outlet are attainable. The precast trench sections and grates are made up of 2' and 4' lengths. Certain 4' channels and all half channels have 4" bottom cut-outs for pipe connections.
AS&G stocks a wide range of Polycast accessories (i. e. channels, catch-basins, grates, etc.) and would like to assist in the proper design of a drain system to meet your individual requirements.
