So, our pool was shotcreted on Tuesday and they poured one of the decks that is going to be stone. All along, the rebar for the deck was on the ground, not blocked up, due to all the traffic in the area. My pool builder assured me that they would block it up prior to pouring it. I was there when they poured it, and looking back, I'm about 90% sure that they didn't raise the rebar prior to pouring. Therefore, the 4" concrete is over the rebar which is simply lying on the fill. My gut tells me this is a huge issue. Pool builder says they blocked it up. I really don't believe they did. What should I do? Should I insist that they tear it up and start over? Tear up a small portion to check? Please advise.
