Hello. I'm installing a 21' steel wall pool. My yard is slightly slanted so one side needs 18" dug out to meet the lowest point on the other side, My question is, how level does my ground need to be? I've reached compacted clay and after 3 days of raking and rototilling I cannot get any further. It's like concrete. I'm within 1 1/2 inches, but not sure if that's ok. Do you think I can backfill an inch with this clay on the low side if I pack it? That would even it out.
Thank you, Mrs D.
