I am in the process of installing a new 24'x52" AG round pool with resin supports. It is going in the same location as the old pool (24'x48" round Doughboy). I will be using a liner pad (Liner Shield) and foam cove. We will basically just rake smooth the sand base because there is no reason to level it - it was level before with the old pool. My concern is in leveling the patio blocks where the uprights will stand. On the old pool, the patio blocks were burried a good 4-6" below ground level of the pool bottom, but on the new pool the instructions say to make them level with the top of the ground. But that means they will be sitting on sand. However, all of the soil where I live is sandy to begin with. Also, the ground that the pool will sit on is lower than the ground surrounding the pool area (it will sit in a depression or "crater" about 4-6" below the existing ground, just like the old pool).
I used a metal pipe and a level to level each patio block against the next, and the they were all level all the way around back to the first block I started with.
I have decided to go back and check them all again using either a water or laser level to be more accurate.
1. Should I be concerned about the sand under the patio blocks? Once everything is up and the outside perimeter is filled back in, how is there a danger of the sand getting pushed out?
2. How important is it that each block by itself sits level on the ground? Is a small level enough to check them against?
I really don't want to be the guy who comes back here and says "Help! My pool is filled and the some of the uprights have sunk!" My feeling is that because the pool area sits lower than the surrounding yard, it should keep everything tightly in place as opposed to a pool that sits on ground that is exactly level with the surrounding ground area.
Thanks for responding!
