Above Ground Pool Base On Clay
Pool Installation Plan
Hello All - See attached drawing. I'm installing a 22' round above ground pool. Because the ground slopes, my pool had to be sunk into the ground a bit. While digging I hit clay, so I went down another 10" thinking I'd need to create a strong base for the pool to sit on.
I'm thinking about using 6" of stone dust that I would compact with a plate tamper. The pool frame and uprights would sit on the stone dust. The liner would sit on top of 4x8 Styrofoam panels from Home Depot. I'm not sure this is the best way to do it.
Any input would be appreciated. I've also considered cutting a trench around the perimeter for weeping tile that would be piped into a sump pit.
You plan sounds just fine. The stone dust would make an excellent base for the pool. If you use the foam sheets be sure to use plenty of duct tape on all the joints.
I recommend using preformed pool cove when using the foam sheets. The foam comes in two types. I would use the type with the sticky back and place it on top of the foam against the sidewall.

If you backfill the area with dirt or stone dust you should not have to worry about drainage. If the area is not backfilled you will need to do something so that the pool never sits in water. I would just backfill around it.
