Putting in a patio w/ a soldier course, it happens to be raised along one side but only about 6-8 inches above grade. My plan was to put a paver on top of wall block, but I haven't done that before and just want to confirm a method. Are the soldiers mortared together and attached to the wall block using adhesive? Obviously poly sand will run out in this application. Can someone give me a hand on this one? PS - this is not for a customer, it's for a family friend. Don't need this to turn into a thread on leaving hardscaping to the pros.
