Hello. We recently purchased an Intex 15ft x 48in Prism Metal Frame above ground pool. We had a landscaper come and clear the area, level it and build our pool. The area seemed pretty level until we got a lot of rain. That’s when we noticed some of our poles sinking and the water level was uneven. So I went around and used a level to see what areas were out of line and I believe 2-3 were really off. Then I took the highest water level area and the lowest and compared them and it’s about 1.5 inches off. And I noticed that when my husband went to swim in it the pool wobbled more. I’m concerned that it’s going to buckle and collapse! We considered emptying it and putting concrete pavers under some or all of them but not sure if that is safe or necessary. What do you suggest? And why is it wobbling?
