Channel drain is usually placed in a driveway, around your pool deck, or a sidewalk.
There are many types of channel drain. Most common is 5 inch NDS channel drain.
To install in a driveway, the concrete must be cut and removed in the channel drain install. Then the concrete is replaced for that finished look.
Channel drain will help protect your garage if you have a negative grade driveway. In other words if water from your driveway floods into your garage, the channel drain is a great option!
Micro channel drain is a smaller version of channel drain which runs around the deck or around the deck of a pool. It helps protect water from flooding off of your patio or deck into your home.
