Thanks to Stonehenge for welcoming me to the forum. I have been reading his posts for awhile now, linked through various products, and have found them to be a great help. I have removed a 25 ' diameter round pool that I bulit into the slope of a hill. Once I had removed the pool and recycled the aluminum, I thought man that would be a great spot for a patio. I decided to go with Pennsylvania stand up broken blue stone - stand up because some of the stones are the size of a car hood and 3" thick! I had put the pool on a bed of beach sand 10" thick. I put the blue stone into this sand bedding. Now my question is about the joints. I have maintained a joint spacing of 2-2.5 ". I have been reading about the polymetric sand. I dont think that is for me as I would needd about 20 bags and the joints would most likely flake apart. The yard where I ordered the four pallets of stone say that I should use stone dust. What is the best material to use for these large joints? Thanks in advance - this is a great forum!
