We have a stone wall (listing picture attached, I don't have any recent photos). My DW backed into it this morning and knocked 3 stones off the top. She said they were in tact but she couldn't get them back in the wall. I haven't had the chance to look at it yet, but I want to be prepared. I would think this should be relatively simple to repair, but i'm no expert. Can anyone let me know what I would need? I'm thinking I probably need to chisel any lingering cement and then re-seal the stones with new cement. Does that sound right? What materials would I need? Thanks

After watching about 20 videos and instructions on how to repair driveway cracks, I've decided on the following instruction: [URL="https://www.todayshomeowner.com/video/how-to-repair-cracks-in-concrete/"]https://www.todayshomeowner.com/video/how-to-repair-cracks-in-concrete/[/URL] In this video, he used QuikreteŽ Concrete Resurfacer to patch the cracks, and then resurfaced the driveway. Lowe's had two types of these concrete resurfacers: [url]https://www.lowes.com/pd/High-Performance-Cement-by-Quikrete-50-lb-Cement/50146060[/url] [url]https://www.lowesforpros.com/pd/QUIKRETE-Masonry-Sealer/3013802[/url] I went ahead and bought the self-leveling one. I've attached the photos of my driveway. The cracks are as wide as 3/4" and seems to be deep as 8 inches, which is filled with dirt over years. Do I need to remove all the dirt inside or just down to 1/2" to an inch?
