My husband and I are having a heck of a time getting our yard ready for our new pool. We purchased an Intex 14' x 42" Ultra Frame, which is going in our extremely unleveled back yard. Our most recent issue is that we placed the pavers and made them flush with the ground before putting down the foam. My question is could we stack additional pavers using liquid nails or something similar so that they will be level with the foam? If not, we will have to dig down 2" more so the foam board is flush with the pavers or add dirt back under the pavers to raise them back up.
