My father put in a concrete driveway in the 60s. Both the driveway and the garage are on a small hill. There are two steps from the driveway going down to the yard. He reinforced the driveway by creating a wall of cinder blocks. This wall of cinderblocks is now pulling away from the driveway. The foundation of the garage seems solid. What can we do to reinforce the driveway. I don't have any photos at this time.
