We installed our pool three years ago and after the first year had significant cracks in the bottom of the pool between each of the in floor cleaners. They just got done repairing the cracks by applying a layer of something over each crack. They then repainted it. I noticed tonight that some of the cracks are returning. Does anyone have any experience on how to fix this problem or is it just something we are going to have to live with. The first picture is before repair and the 2nd pic is after repair.
