Hi! I purchased a house six months ago and just before closing was told there was a filled in pool so now I'm weighing options... creeping on message boards . My real estate agent tracked down a pic. I did a little digging and found what I think is the near left side wall and some chunks of concrete so it looks like they broke up the decking. Is it called decking? Can't believe this is the one thing they may have done a proper and thorough job on.
