We are beginning the installation process of a used above ground pool. The grass has been removed, and the ground is sort of level. My husband thought that it would be best to put the pavers in then level the ground to the pavers. The pavers are all leveled. When a board is laid across the pavers, you can see high and low arears in the ground in the middle of the pool area. I think he should work on getting the ground more level. He tells me that when the sand is laid and leveled it will take care of all the divots. Our ground is clay and very hard to work with. What is your opionion.
