Surface water on hardscapes is more than just a slippery problem. It can lead to mildew growth, concrete staining, and erosion. Here's how to prevent it. Drain moderate flows from driveways, concrete & paver patios, pool areas, courtyards, & walkways with the Spee-D Channel Drain, the #1 bestselling channel drain in the USA, and part of the NDS Profile Channel series. Features patented flying buttress design for load-bearing support; bottom flanges with anchoring lip for straight installation & prevents floating. Made of polyvinyl chloride, it can be cut to size. Channel drains, also called trench drains, are long, narrow drains and as part of a complete drainage system, collect water from surrounding surfaces and direct it away to drain pipe. The water is carried to a discharge point downstream such as a pop-up emitter, or to percolate into the ground with a dry well or infiltration trench. NDS channel and trench drains are designed for durability, drainage, and performance, and are a proven alternative to traditional concrete drains.
