when wet, garage floor leaks into room underneath
I have a room under the garage that water leaks into. There are small cracks in a few places in the concrete that will leak whenever we bring a car into the garage with snow or even rain. Two years ago, I had the floor sealed (cracks with a flowable epoxy in the cracks and then the whole floor with an epoxy that was much thicker over the top of the floor). We thought it was fixed, but this year we have the problem back. We talked to one company that wanted to strip the floor, reseal the floor and put on a different coating. It was very pricy and there was no guaranty that it would even work. I have read about flexible epoxy that may be better and even read about drilling in the floor and pressure sealing the concrete (similar to how the repair windshields on cars). Does anyone have an idea of what I can do?

You must still have movement in the floor system of your garage. The epoxies that were used apparently were too brittle and failed. There are numerous rubber membranes that you could apply to the floor, one that I have used in commercial balconies and outdoor patios is DecTec. It is not cheap, but also will not have you addressing the same problems down the road. Research your options that are available in your area. Dec-Tec is not the only membrane out there and it only comes in 6 or 8 foot widths, so heat seaming is needed. You can probably find one that comes in a full sheet that can easily cover your garage in one piece.

Thank you for your reply. Is there something that can actually seep into the cracks and then set up that will also allow for movement? It seems that it would be valuable to have something that was flexible, thin and runny, and would bind and set to cement. Perhaps I'm just wishing for something that doesn't exist at this time.
