The NDS 764 is a 1-meter channel drain kit for moving surface water away from driveways, patios and pool decks. It includes a pre-sloped channel, two plastic grates, one end cap and one end outlet with stainless steel grate screws. The pre-slope helps water flow toward the outlet without pooling, and the interlocking ends let you join several kits into a longer run. It is rated for pedestrian and light vehicle traffic, so it suits residential hardscape drainage rather than heavy-duty road use.

The NDS 764 is a 3" Pro Series channel drain kit for surface water drainage. It is used in areas such as driveways, patios and pool decks. It suits pedestrian and light vehicle traffic.
The channel is made of polypropylene and the grates are high-density polyethylene. The channel is pre-sloped to move water along. Sections connect with an interlocking system.
For installation, dig a trench 6" wider than the channel and at least 4" deeper, then pour a 4" concrete base. Set the channel sections starting at the outlet point, with a slope of at least 1/8" per foot. Encase the sides in concrete, leaving the top 1/8" below the final surface. Let the concrete cure before installing the grates.
