I am have convinced a local developer to give me stone from a old barn that is being demolished. I am not sure what kind of stone it is at this point other then cosmetically it looks great and that there is some mortor that will still be attached that I am not planning on removing at this point. I am not by any means going for perfection here but the stones are 6-8 inches thick. Am I crazy to even consider using this to build a patio? Does anyone have any experience constructing a patio with stone this thick? Any advice would be greatly appreciated.
