I have a driveway that goes down from the garage to the street, about 25-30 feet. At the very bottom of the drive, just as it touches the curb/gutter, I have patches of concrete that have chipped and cracked away after 28 years of snow, ice, and salt. Is there a way to patch the spots (8 inches by 15 inches or so)? How deep do I chip out the old concrete and what products are best for filling the holes?

Thanks. Tom M
