Our pool is in the process of renovations. I am having trouble deciding what to choose for a decking to put on top of an existing concrete. I like the flagstone look that will go best for the lagoon style pool. The pool edges is covered with 1 to 2.5 in of coping and big boulders. My dilemma is deciding which flagstone to choose real vs synthetic vs concrete. The prices are about within the same range. I guess it'll come down to maintenance and looks. I am also converting to salt water system and getting the pebble sheen finish. I just need some advice. After months of research from contractor to products, I am absolutely exhausted.
