I am having a pool/spa that is currently being tiled and coping installed. The rear bond beam is raised and is topped with 2x12x24 silver travertine. The bond beam is actually 14-15 inches wide. The back side will be landscaping and flowerbed with no decking so nobody will really be behind the pool. My concern with this is that I thought the coping was to protect the bond beam and should overhang instead of the last 3 inches filled and troweled with "plaster". Seems like PB is just saving money instead of buying 16" wide coping. My other concern is on the front side of the pool with the same issue. The deck is supposed to be concrete and this seems like it would "couple" the decking and the bond beam and the expansion joint would only protect the coping. Feel like their are conflicting opinions on this forum of the correct method. Also there is rebar that came out of the bond beam and will connect into the decking so what is the difference. Main confusion is that it seems like there are a billion stories of pools having to be repaired because of the coupling of the pool deck and bond beam causing tiles popping, cracking, etc. Any consistent opinions would be much appreciated.
