POLYCAST 700 Series is a polymer concrete channel that has a built-in .65 percent slope that allows the system to achieve flow rates of 470 GPM. The channel depths and dimensions match the POLYCAST 600 with the exception of the frame that is included to allow for increased weight distribution. The installation chairs tighten the joints between channels while aligning and leveling the drainage run. Each installation chair is secured to the ground (using your own rebar), ensuring that the channels will not float during the concrete pour.
