Hubbell’s POLYCAST® 400 Series is a residential-grade, polymer concrete trench drain system designed for light traffic applications such as sidewalks, patios and tennis courts. The POLYCAST® 400 Series channels are non-sloping. Channels are fitted with galvanized steel slotted grates that can withstand the weight of light vehicles such as lawnmowers and golf carts. The slotted steel grates are pedestrian-friendly and bicycle-safe.
INSTALLATION
Installing the POLYCAST® 400 Series is made easier with installation chairs, which screw snugly into dimples located at the ends of each channel. Staked to the ground with rebar, POLYCAST® installation chairs allow contractors and homeowners to secure and adjust channels on-site for an easier installation. Solid end caps and 3” diameter pipe outlets come standard with the 400 Series. You can also drill out the channel bottom “knock-out” to attach a pipe as a bottom outlet.
OUR RECOMMENDATION
Though originally designed as a low-cost option for the homeowner or light-duty drainage project, POLYCAST® 400 has limitations. TDS recommends the POLYCAST® 600 series which has a wider selection of grating as opposed to the one-slotted galvanized steel option for this system. With the 400 series, you get a neutral channel and one grate option. The POLYCAST® 600 is comparable in price, has a higher flow rate and is a pre-sloped system.
