I could use some options! My house has a large concrete driveway on an incline and it has been present for 13 years. The previous owner used salt in the winter (instead of sweeping or shoveling it) and now it is pitted. Some pits are large, measuring close to 1 inch deep and 1.5 to 2 feet wide. Some are much less severe. The surface is beginning to flake away. The rest of the concrete is in great shape. There are no cracks, heaves, or buckles. I want to do something to give my driveway a smooth surface. I have googled concrete repair but I find how to repair steps and not something as large as this driveway. Can (and how) could I go about patching the concrete or should I have someone put a coat of asphalt over it? Thanks in advance!
