Water Under Garage Door


Unless the pics are showing some kind of optical illusion, it appears that you have ample pitch outside the door already, so I really don't see any benefit in grinding.

Does the buildign have gutters?

If you can't find a bottom weather stripping bulb that you have confidence in, the only other suggestion I can make is to find the weather stripping that gets applied directly to the floor.

Water Under Garage Door


I do think there is ample pitch but I was wondering if it goes far enough under the door.

There are gutters (that are clean from debris) on the building.

Could it be that the door doesn't close tight enough?

My last resort is the rubber thresholds that you glue down. I hope I don't have to do that.

After looking at it again, I'd have to say NO. Common mistake for the cement finishers to have little understanding of were the door will sit. Not a good excuse by any means, because now you're stuck with it.

You can certainly grind all the way to the inside of the door, but it's going to mean you have to lower the entire are 1/2" to 3/4", which is going to take a long time with a 7" grinder & diamond cup wheel. The one issue afterwards as well, is that you'll be left with exposed aggregate, which is not only ugly, but can deteriorate much faster than a finished surface. So, y ou'll probably want to put some kind of thin patch over that as well, and give it a light broom texture.

In the mean time, I would try sawing a few kerfs into the exterior portion of the concrete, about 3/4" down, to see if that will be of some benefit.

Can I just grind a slope under the door that blends into the existing slope instead of taking the lowest point down another 1/2" to 3/4"?

I'm not sure what a kerf is. I'll have to read about that.

From looking at the pics, I highly doubt it, but it may be worth a try first.

I'm not sure what a kerf is. I'll have to read about that.

A kerf is simply the width of the saw blade.

Here's my suggestion to try from the last post:

I'd saw the yellow line at the back edge of the door so you have a great, visible line to deal with (This should also help with minute amounts of water)

The red lines could be about 3/4" deep.

Thanks. I understand and it sounds easier than grinding.

Could it be that the door doesn't close tight enough? I could call the door company to adjust the down-stop on the door.
