Most cities dont allow drains in garage floors. Mine doesnt. A garage floor should be sloped so that it can be washed (hosed) and swept/squeeged out. I dont think it would be a good idea to put so much slope on it that any residual water from a car would run out. My floor has no slpoe at all that I can tell.

Yes, We have a floor drain. It is allowed in our area as long as it is residential. We had a sloped floor at our old house. We wash cars alot and it created alot of ice outside the garage doors from all the water. Like the drains MUCH better.

It's possible that the floor isn't level or even pitched as the builder said. Frankly, they don't put a lot of effort into garage floors.

There isn't a lot you can do about it. I suppose you could complain to the builder but the odds of getting him to jack out the floor and pour a new one are slightly better than winning the Mega Millions.

I know this isn't much consolation but the water will pool at the same spot so just avoid storing stuff there or put it in a waterproof container.

The slab near where I enter into my house cannot be sloped towards the exterior door. With melting snow the water is also coming towards the front of the garage right where I walk! So when I come out of my house and walk down the two steps I take a few steps and walk right into pooled water ! Or when I get out of my car and want to come into the house again, there is that pooled water! I originally put a throw rug there to catch dirt and that got wet too !!

I have to find a solution - oh, no I don't "the builder needs to find the solution"
