The homeowner has a bunch of square cut flagstone left after a previous project. He is wanting a walkway done. The pieces vary from 3/4 to 1 1/4 in. thick. I have laid a ton of pavers but i am new to natural stone. What is the process of laying these. I would prefer to lay it on a dense grade base versus pouring any concrete to set them on. The sand and how to restrain the edges is my biggiest question. I was planning on using gator dust for the joints. Any tips will be appreciated.
