we have put a contract on a new house. the concrete driveway was laid a couple of weeks ago. ive just tried out the new driveway for the first time. right at the road where the driveway starts, there is a steep slope and my car scraped on the bottom. the builder and the real estate agent say that thay have had no problem going down the driveway. my husbands car didnt scrape going in from one direction, but did coming from the other direction. does anyone know if this can be fixed without tearing out the whole driveway?
