I set up my new Intex 18' x 52" Ultra frame pool at my house on Friday. Right now, it's set up on a concrete pad that the previous homeowner used as sort of a basketball court area. The area was the right size for the pool and seemed preferable to my lawn, which is pretty uneven. The posts are all sitting on concrete and I put two layers of ground cloth down to protect the liner. I will admit that I should have done some measuring to confirm that the area was level rather than just looking at it and assuming it was based on appearance. That's definitely my screw-up. Now, I've gotten the pool full and there is roughly a 2 1/4" height difference from one end to the other. I'm not sure what the allowable tolerance is for these being level so I don't know if this is too much. My hope is to get through the rest of this season (probably Labor Day or so) and address the issue next year before setting up. Would this be ok for a couple of months, or do I need to tear down and start over? When it does come time to level (now or next summer), do you have any recommendations? I've read that sand is not ideal and that digging down to level things out is better than adding dirt, due to settling. However, that's a little easier said than done with a concrete pad. Is there a leveling method that makes sense for this that doesn't involve tearing up the concrete pad? Any advice you can give me would be greatly appreciated. Thank you so much!
