We are just beginning to have an inground pool installed. It is a Pacific pool with the gray plastic-looking walls with black braces behind it. I think this is the stage where they will pour "footings" according to the PB. They are doing that tomorrow. I looked at the outline of the connected panels tonight, and one of the walls is leaning backwards. A slight deviation I could see, but this is leaning backwards a lot. Once they pour the footings is that wall going to be in that position permanently or is this just an approximate location for the walls?
