I'm thinking of having my pool deck redone. It's some type of Kool deck or a cool deck, not sure which. It is peeling and cracking and is 9 years old. I also have a tree root that grew under the deck walkway and I might have to have it broken up to get it removed. I've seen older thread on the same subject and people recommended travertine or acrylic concrete as the best options for a pool deck, besides Kool deck.
