I have a garage floor that is built perfectly ……wrong! The best I can determine, it is dead flat and level. Instead of being sloped just a little down toward the garage doors, it is level (I didn’t build it). When it rains, the water seeps in under the doors. New gaskets on the bottom of the doors did not help; the water just comes in at the edges. The water will sort of wonder around, with no particular place to go for 15 or 20 feet inside the garage. What I need to know, is there something I can do to stop this.

how much of an overhang do you have from your roof. I had a simialr problem with my garage. I have a 18" overhand. I added gutters and I poured a pitched apron in thr front with a 1/2" lip so the apron is lower than the garage floor. my suggestion is to screw down into the concrete a small piece of rubber tack strip so when the garage door presses down on the floor, there is a true rubber to rubber seal.

My overhang is about 14 inches but it is 2 stories up. I only get water when the wind blows from that side. The concrete drive way comes right up to the garage floor, and it IS pitched down just a little. The water that comes in under the doors is what falls on the outside of the door and lands on the floor that sticks out under the door. Then it just seeps in.

What about putting a slope on the part of the concete outside of the door? Or maybe a pipe and a grate? Or maybe step down the concrete that is outside of the door? Hard to say without looking at it....

Got the same problem in my shop. What we do is put a strip of carpet foam pad under the door and it stops most of the leaking.

Cut the apron out and put in a surface drain/grate the length of the door. The bottom of the door should sit a good 3/4" below the garage floor suface. Make sure the new drain is at least this much lower than the garage floor. Either extend the apron under the door, or cut a pocket into the garage floor for the door to fit down into.

What about something like http://www.cabelas.com/cabelas/en/templates/links/link.jhtml?id=0004131520779a&type=product&cmCat=search&returnString=hasJS=true&_D%3AhasJS=+&QueryText=garage+door&_DARGS=%2Fcabelas%2Fen%2Fcommon%2Fsearch%2Fsearch-box.jhtml.22&Go.x=0&Go.y=0&N=4887&Ntk=Products&Ntx=mode+matchall&Nty=1&Ntt=garage+door&noImage=0&returnPage=search-results1.jhtml

I'd do what Fingers suggests. Use a circular saw with a diamond blade and cut a bunch of kerfs in the concrete. Then use a hammer and cold chisel (if you don't own a hammer drill) or rent a big demolition hammer drill and knock out the concrete. You could just cut a trough about an inch deep and see if that works. Make a lot of saw kerfs -- at least one every inch -- so you can clean up the bottom of the trough and make it relatively smooth. Make it slope a little to one side or to each side for drainage. If that doesn't do the job, go ahead and install the full drain. But, in that case, you will need some slope away from the garage so it can drain to daylight.

Hard to say, again, like mentioned above until seen.
All depends on the grade of what the property is set on and what drains can be allowed from the grate and where they can be led. Could be an easy fix or could be some digging??????:eek:

Send some pics of the property(garage area) so we can make a better assessment and perhaps give some better/more appropriate advice.:exactly:

If a proper outlet for the apron drain can't be done, digging about a 2'-3' deep sump and filling it with loose gravel under the drain will provide relief provided the drive slopes away. Biggest thing is to get the bottom of the door and apron below the garage floor level.
