Blacktop driveway even with garage floor the land is level no drop offs how do I keep water from going in the garage when it rains?

Sand bagged it or do what we did. We broke up the drive way in from of the garage and dug a trench, we have never had a problem since.

Beer, I had the same prob. I used a torch, 2 inch piece of cold rolled steel and a big hammer, laying the steel at the edge of the cement floor and beating a slight indention with the hammer. Worked great for me with little cost. I owned a torch but have seen them at Lowers rather cheap. Good luck

You don't say weather the door is tight to the floor or if has a rubber seal at the bottom.

If not you can put one on very easily..

If this is not the problem describe the situation.
