How To Slope A Garage Door Opening

On A New Garage Floor Pour

Mike here,

When I pour a new concrete floor for a garage, I always slope or taper the garage door opening so any rain water that runs down the garage door will not run under the door.

On most garages, there's always about 8 inches of concrete that's outside the garage door when the door is closed.

If this area is just left flat, water will collect there and run back under the garage door and into your garage.

There's a simple solution to this if you know what and how to do it.

In this video, I'm showing you how we make sure no water gets into the garage from outside the garage door.

When we pour the garage floor, we wait for the concrete to stiffen up a bit, then we slope that "outside part" away from the door.

We have a technique we use to do this and the video will show you how.

Check out the video below to see this concrete finishing technique.

If you missed the HORSE BARN floor we poured, you can check it out below.

I showed you how we sloped the floor to two floor drains while pouring this new floor.
