The benefit of concrete deck swimming pools over wood deck swimming pools is that the concrete just last longer. Pool builders will sometimes suggest concrete if they sense that the client wants a low maintenance solution. A wood deck can warp and wear out and next to a swimming pool, it is nice to have a reliable deck that can stand the test of time. The concrete swimming pools are easier to maintain because in most cases you can just spray them off. The concrete swimming pool deck is better for the environment because you do not have to cut down trees.
