Polylok

The Polylok Heavy Duty Trench Drain system has an H-20 wheel load rating when cast in reinforced concrete. This drainage system offers a modular design with interlocking components to enable quick and easy connections. Each segment is four foot in length and comes with a reversible ADA compliant grate that can be mounted flat or turned over for a 3/16″ convex surface.

Polylok channels are engineered with easy installation in mind.  Each four foot segment can be connected or cut down in 12″ increments using the molded cut grooves. Each channel segment has eight anchor positions to allow rebar installation that prevents floating. There are two sections on each segment that allow 2 x 4’s to be installed which aid in leveling and anchoring prior to the concrete pour. Four drainage ports are molded into the bottom of each segment for easy removal with a saw for 3″ and 4″ SCH40 or 4″ SDR35 connections. Each segment is shipped with screws to fasten the grates to the channel and to secure the interlocking pieces. No need to visit the hardware store.
