I will be scraping a dirt/gravel driveway down two inches and laying flat stones of various sizes and thicknesses. Need to have the tops at the same level, so some will need to have something underneath to raise them.
All will need some thing to keep them from moving easily. Ground is more gravel than dirt, such that I’ll have to use a skid loader to grade it. (Shovel couldn’t penetrate and tiller took hours to get a quarter inch off!)
Which is better, mortar or cement?
