 A driveway to the garage floor, maybe that garage floor might even be an inch higher than the driveway. And then there's that gap, and that driveway's settling right at that point. So you would clean that gap out, you know, with anything that you can scrape out, dirt and weeds, and you've probably got all kinds of gunk in there. You might even have a little filler left down in there, and you can get as much out as you can. That'd be best.
