My gunite job was completed on Tuesday. My pool is being built next to a South Florida lake so builder is dealing with water table. The sides of the pool and most of the bottom have gunite applied;however they did not gunite the deep end around the drain and there is still rebar showing. I called the forman and he said not to worry that it's normal where there is a higher water table, it's necessary. He said they will eventually fill that area in with an even stronger material.. Is this really normal? I am really concerned..
