Ok so long story short we go a lot of rain with the recent storms. Rain = GOOD for our rain fall totals here but not so good for the pool before I re-sloped the yard away from the pool on one side. Well this has been a growing problem since early spring when our pool over flowed due to lots and lots of rain causing 9 posts to slowly sink. Now mind you all 18 posts were set on those 7x12 concrete patio pavers on virgin ground when we set up the pool last July. The side that sank was roughly 3/4" lower than the high side from the get go so naturally when it overflowed it went out the lowest point. This was in early march. We also have been able to swim since mid march here. My observation was that with each day we swam and the walls flexed and moved so did the posts and you could see the water coming up out of the soft wet soil around the pavers and over time they eventually started to sink. The way the yard was leveled for the pool didn't help because the area in question would hold water if it was rainy or wet. So now as I mentioned earlier the yard and drainage has been corrected and tested with the rain the other day. Today I finally took a deep breath, grabbed the hydraulic floor jack and a 2x4, set up the dumpy level and slowly went around the pool jacking up the posts and shimming the low ones up with thin pieces of flagstone until I had everything back to with in 1/4" level from being completely level. The worst post was about an 1-1/2" low, two about 1" low, and the remaining 6 not more than 1/2". Not enough to really be a problem but my OCD made me make the top rail completely level. I wish I would have taken pics but I was too focused on makin it as perfectly level as I could again. I mainly just wanted to let others know that it can be done successfully and that even sitting on pavers that depending on the soil conditions the pool legs can still sink in poorly drained areas.
