Question:
We built a new garage this last year, and finally got the garage doors
installed. The interior slab is sloped 2" from back to front for drainage.
Unfortunately, the slab edge right in the door openings apparently slopes
ever so slightly into the building instead of out. The result is that every
time it rains, water hitting the garage door slowly seeps under the garage
door seals and into the garage.
The slab is level from side to side in the door openings, and extends out
beyond the garage doors about 6" (to the outside of the foundation wall).
The garage door seals are new, and in very good condition.
The doors are on a gable end wall, so there is no roof overhang above the
doors.
As it is now, I don't dare sit anything close to the garage doors or
they'll end up sitting in a small puddle of water. I also need to store
woodworking lumber in the garage and don't want all that moisture inside
the building.Anyway, I'm curious what options I have to eliminate this problem?
Answer:
Putting a seal strip like this on the floor may work to keep water
"out", but if I have water inside the garage (i.e. dripping from the cars),
then it won't be able to drain out either.
I checked my slab yesterday with a level, and it seems to slope nicely
except for the last 6" or so beyond the door. The garage door essentially
sits in a small trough that is about 1/32" or less deep. It's not much, but
it's enough to let the water seep under the door.
Anyway, I was reading some stuff on concrete grinding the other day and am
curious if anyone here has ever had that done. If I could have just the
edge of the concrete ground down with the proper slope, it should keep the
water out while still letting water drain out of the garage itself. My
biggest concern would be price and appearance.
