Build Pool On Clay Or Remove

by Sara

We just picked up a used 15 X 30 foot pool. We live in an area with heavy clay soil. What is best for a base?

Remove grass layer, place concrete blocks with crushed limestone and sand mixed with dry concrete on top? Or should we be pouring a concrete frame. The pool has 6 supports on each side.

Thank you,
Sara




Hi Sara. You should be just fine by removing sod and leveling your existing ground. I would recommend blocks under the end uprights and under the braces. I would then use a sand base to install the liner over. If the clay is not workable as far as leveling goes then you can remove some from the outer edge of the pool. This can be replaced with crushed limestone to make leveling easier. Usually an area one foot wide and about four to five inches deep works fine for that.
