Channel & Trench Drains & Grates
Standing water on hardscapes can lead to slip hazards, pest breeding grounds, and erosion. These long and narrow drains intercept, collect, and convey runoff to drain pipes, ultimately reducing runoff on the property.

The fall in each sloped section of Dura Slope channel is 0.34 in. Each section comes with a built-in 0.7% slope. The neutral sections have flat bottoms.
The Dura Slope Channel and grates have been tested to the AASHTO M-306 and EN 1433 (DIN 19580) test methods by an independent AASHTO accredited lab. The channel's strength exceeds the standards set forth by these tests. This rating is suitable for loads of 61-175 psi including medium-duty pneumatic tire traffic, autos and light trucks at speeds less than 20 m.p.h.
Without the use of neutral sections (no bottom slope), the maximum length run is 96 feet. With the use of one neutral section in its designed place, the maximum length run is 132 feet. There will be 8.07 in. of fall in these runs. The channel can be lengthened by adding additional neutral sections. We do not recommend connecting more than 4 consecutive neutral segments together to allow for proper flow and prevent standing water in the channel.
