Here's a link for you, Pat:
Ann, thank you so much!
We borrowed a large drum roller from the high school football field.
Filled it with water soaked the ground and rolled over the ground area several time. Finally we got the flattest area for the new about ground pool we put up for our g-children.
Kathy, thank you so much!
Top soil then sand then set pool you might want to think about having the dirt Doug out you could dig down like 3 feet and drop the pool in the ground
Thank Leveling the yard for an above ground pool is an absolute must and a whole lot of work! I think my son and his wife wish they had researched what would be required before they purchased the pool!
thanks for the help Ann, Kathy, and Kmdreamer!
