Concerned about wall lifting out of track.We have a 15x24 oval swim n play. We filled the pool once and the buttress'started leaning back so we drained and added dirt,tamped,and leveled with new patio blocks but one area is raised and we don't know if we should stop filling? What are the options for correcting this without taking the whole thing apart? I included some pictures. Also we are planning a deck but unsure of what to do with the ground besides perhaps chat and drain pipe? Any advice would be greatly appreciated.
