I have a detached 2 car garage that sits back behind and to the side of my house that is accessible from my driveway that runs along side. I recently noticed that the driveway level is about 2-3 inches higher than the garage floor, so when it rains the the water tends to run back and collect in puddles in front of each garage door. I was doing some research on the internet and read about a concrete apron to raise the level of the ground that the garage doors sit on to the same level of the driveway. I don't anticipate being in the house much longer so I'm looking for the most cost effective way to fix this problem. Any advice would be appreciated.
