I have kool deck around my pool and it probably was installed about 20 years ago. It is cracking and chipping, so it is time to go. The patio which connects to the pool decking is travertine tile. I would like the entire area to be the same product, so I was thinking about removing the tile and kool deck and putting in all travertine pavers. Can these be installed on top of the concrete? I am also trying to get a rough estimate on the cost. I have about 1,300 square feet that would need to be covered.
