Article Intro

Channel drain is one of the most effective ways to get rid of standing water in your driveway, garage or walkways. Knowing the proper way to install trench or channel drain is important to make sure it's working correctly.

One of the best solutions to keep your driveway, garage or walkway free from standing water is installing channel drain. Also known as trench drain, this type of residential drainage requires a specific method of installation to make sure it stays in place. Check out the video above to learn the proper trench drain installation method or keep reading for the step-by-step guide.

Step 1: Dig the Trench

Your trench will need to be deep enough to allow a 2-inch bed of sand under the channel. It also must be wide enough for 4 inches of concrete backfill on each side.

Step 2: Compact the Sand Base

Fix a string at the finished height of the channel. If you’re using a bottom outlet, determine where it’ll be located and use a 3-inch hole saw to open it. Once that’s all set, use your shovel to tamp the sand down.

Channel Drain Installation: Dig a trench that will accommodate 2" of sand under the channel and a minimum of 4" on both sides for concrete backfill.

Step 3: Place the Trench Drain

Using the string from step two as a guide, place your channel drain to set the grade. Remove the grates to get access to the end cap and end outlet. Connect your 3- or 4-inch drain pipe to the end outlet and use the tabs to connect it.

Attach 3- or 4-inch PVC, SCH 40 or other drain pipe to the end outlet of the channel drain.

Secure the sticks of channel with ½ inch rebar and wire ties. If you aren’t doing a straight across installation of trench or channel drain, use a quad corner connector.

Secure channel drain with half in rebar and wire ties.

Tip: Driveway trench drain can be cut to custom lengths to fit your application.

Step 4: Backfill with Concrete

Float the channel 1/16” below the finished level of concrete and then backfill at least four inches on both sides. Smooth the concrete out and let it cure before exposing the channel to traffic or removing grates.

Backfill both sides of the channel trench drain with a minimum 4 inches of concrete.

Tip: Use tape to cover the top of the grate and the side grate lock channels to prevent them from filling with concrete. It’ll make it easier to remove the drain grate later if it needs to be cleaned.  On the Dock | Home Inspiration and Advice |
