POLYCAST® 700 Series is a polymer concrete channel that has a built-in 0.65 percent slope that allows the system to achieve flow rates of 470 GPM. 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.

Before we can ship your pre-sloped drain order, a layout will need to be approved by you. Once we receive your order, we will contact you via email with a layout drawing showing what channels you will receive and the order they need to be installed. We will need a confirmation email from you that you accept the layout. If you choose all neutral channels (no slope), please note this in the ‘Order Notes’ during checkout. A layout is not necessary with neutral channels. Please review the inlet/outlet depths shown above for each system length. (Add 3/4″ to include the channel bottom thickness) TDS reserves the right to choose the channel depths based on availability. If you require specific channel depths, please note this in the ‘Order Notes’ during checkout, and we will do our best to accommodate the request.
NOTE: For proper installation, grates must be in the channel during installation.
2-foot kits are intended to be an extension and only include one install chair and no end caps/outlets. Other accessories are to be purchased separately if it is intended to be a stand-alone kit.
