Pool Base And Limestone
We were in the midst of leveling the ground for our 27' above ground pool but then it rained for about 2 days and one side of the ground got extremely soft and muddy and water started to puddle there.
So now we must re-level it because it is no longer completely level, but the ground on one side is still soft and even when it dries it is soft.
Would anyone recommend getting some crushed limestone and using it over the soil and then placing the sand on top of that? The limestone would be used to ensure that when the patio blocks and rails are put down the ground does not sink. Or should we just wait until it gets very hot, and level the ground and place the rails and patio blocks right on the dirt?
I would do exactly as you suggested, level the area with limestone.
You might consider going one step farther and digging an 8" deep by 2' wide trench around the perimeter of the pool. Fill this up with limestone. Your rail will fit right in the middle of the firmly packed base. The blocks would then be set into the limestone leaving all of the rails resting on a firm, level base.
