water leaking under garage door?

[nervousJessica]

I have some water coming in under a portion of my garage door that is over a footing. Looking at it the footing is a little lower than the slab, so I guess the weather stripping isn't working well there. Also there is a fiberboard joint between the footing and the slab that falls under the door so I guess that would let in moisture too. I'm not sure the best way to fix this...so I figured I would ask you folks! Should I put more weather stripping on the door? add material to the footing to raise its height? something else?

image attached...which hopefully makes more sense than my description

LOL...at least I'm not the only one with this problem. I wedged a sheet of EPDM rubber I had lying around under there for now but it's not a good solution

You might want to try a garage door threshold

The root of the problem is improper drainage on the outside of the door. Any concrete extending beyond the face of the door should pitch away at least a 1/4" per foot. If water doesn't flow away from the door, it will find a way under it somewhere.

OK, this is crazy, I have the exact same spot too. I have a rubber threshold and still have a little puddle there. Mine's a new floor and door. I have a theory I haven't been able to prove yet. I suspect the big rubber gasket attached to the bottom of the door is accumulating the water that runs down the door, then diverting it to that corner. I recently built a little dam on top of that end of the gasket with RTV. I might make a small cut in the gasket facing away from the door, giving the dammed water a way to leak out away from the door. Fortunately we don't get much rain in AZ so it hasn't been a huge problem.

I agree that the proper slope should eliminate this, but that's not what the concrete guys gave me.

Bsws that's a solid theory!!

This is the kind of threshold that often works. I don't have one because its a PITA if you squeegee things out of garage or hose garage out. It goes on the concrete and counter flashes the seal on the door.

Definitely does not fix the root issue.

I have a customer who is also a concrete contractor. He added a saw cut in front of the door and he says it didn't fix it completely, but works most of the time -- melting snow, downpours and windblown still come in but average rain does not make it. Not tested it myself.
