In reality you don't even need a channel if the garage floor is slightly sloped from the left and right sides into the middle and from the back to the garage door. From what I've seen people typically only slope the floor from back to front.

The problem with that is the center channel won't get sealed off by the weathestripping on the garage door. If you have a heated garage in -20 temps cold air will rocket through the gap and your bills will be maxed out.
That leads me a problem I'd love to hear a solution to if anyone has one. My garage is sloped correctly and water runs to the garage door. But the weatherstripping prevents the water from running out and it pools at the sides of the door, ruining whatever is stored there.
I've tried drainage socks which can't keep up. Any other ideas to either contain or drain this water?
