This 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.

Layout Info:
Before we can ship your pre-sloped drain order, a layout will need to be approved by you. We will contact you via email with a layout drawing showing channel depths to be shipped. Once layout approval is received, the order is shipped.
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. 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.
