Winter is here, how do people contain the rain/snow brought into your garage under their cars? In my under-the-house 2 car garage, the drain is between the bays and also is the highest point of the floor. Any water runs immediately to the front drywalled wall. Any good fixes?
When the public finds enough concrete contractors that actually know how to or will, ever screed the concrete to pitch to the drain(s)..... one of mankind's greatest accomplishments will be recognized.
Many ways to cheaply and conveniently help your problem have already been mentioned, but are not permanent, hands free solutions. Your real solution will depend on your budget, your skills and how much labor you may or may not want to do. I will just mention some of the solutions I know of, and others will chime in too... ...
The home we just moved from my garage floor did the same thing, except the snow/ice water drained towards the house and went under the floor joists. So I ground the floor down, and brought the wrongly pitched floor up higher with concrete surfacer, then laid the whole one car garage with porcelain tile ....so that the water drained to the center and drained out under the 10 ft. wide garage door.
Pretty radical solution I know,it was very labor intensive and not cheap to do., but just one of many solutions. You could put in a trench drain all along your wall where the water is draining towards and then drain the water through the outside wall...where it may freeze in the pipe in the winter... unless insulated /sleeved properly...
You could grind down the whole center of the garage floor down to where it pitches to the drain. Then to hide the grinding process done... lay some sort of tile, epoxy it, or even Race Deck tile it. ...
Whatever you choose to do, you need to think about how long you intend to live in the house, and that what you do to the floor will affect the sale of the house to any prospective buyers either in a positive, or negative way. Good Luck. JMO
