Our Vinyl liner was floating and the PB removed our old liner. Around the perimeter of the deep end about three to four feet above the bottom there is a crack and water is flowing in. This pool was just installed last year and has not been used. The PB has dug a trench and we have put a sump pit in beside the pool. This sump pit is not as deep as the cracks where the water is coming in. Our water table has dropped some so hopefully this trench that has been dug will be able to alleviate the pressure and prevent a liner from floating again. Anybody have thoughts on cracks in the concrete with water coming in? You can visibly see water coming in like a small water fall. Can this concrete be patched ?
