Garage overhead door leaks

[CDUB51]

OK I have a Door the faces north brand new 2 1/2 inch 10ft by 9ft high brand new seal on the bottom brand new trim on the outside. Rain its the door and leaks door the Door and under the seal and in the garage I have adjusted the door tight to the seals and still nothing. Anyone have Ideas how to stop this.

Not sure what the heck you are trying to say in that sentence. When the water comes in, is it pounding against the door itself? I am assuming you have no overhang above the door. A door seal at the bottom will slow and alkmost stop water infiltration, but water, given enough time will wick its way under the sill. If you had a recess the door would sit into, then it would not leak back in. To help it at the bottom, you may want to cut a control joint across the door opening where the seal hits. As far as the door itself, water can find its way in through capillary action. It all depends on how hard rain is pounding against the door. As far as the side seals, they wont stop water altogether due to the rough surface texture of a door. It will let water seep in. Some of the water may be coming from behind the wood or plastic portion of the seal as there is no caulk put down before they mount the seals. There is no miracle cure to stop it. You may have to caulk some corners, you may have to pull the side seals off and put them tighter to the door, you may have to adjust your rails or rollers somewhat to get the door a little tighter. And if it is seriously that aggravating, add an overhang to keep rain from hitting the door.

It is a moving wall, its never going to be 100% sealed, this is the unfortunate reality...

Check concrete slope at the threshold, it should be sloping away from the door/building, but often it goes the other way, causing this issue

A door, any door is a compromise. It has to be loose enough to

open and close, yet, tight enough to keep the wx outside.

If the door is mfg correctly, it should have an ogee cross section

where the sections mate top and bottom. This is such that the

front of the joint is lower than the back of the joint. If in fact you

have a door made that way there should be little or no intrusion

of rain, unless it is wind blown and then it will leak no matter the

construction. Most times, as suggested above, the slope of the

landscape, driveway, apron, or whatever, should be downward

away from the house or garage, and is a detail easily overlooked

by contractors; " Yeah, I looked at it and it's OK, just keep working."

At home, living on an island, we had a raised floor in the garage.

1.5" higher than the apron, and with the doors facing west (into the

prevailing wind) the floor stayed dry as long as the tide wasn't too high.

If I were you, I would consider an overhead shed roof in the front of the

o/h door, with a gutter and leader. It may not be to your astetic liking, but

it just may help the situation.

Well I think your right, do I have a concrete guy come out and sand it or grind it down? Hope this fixes it, if they can do the above.
