My pool is about 2.5' into the ground on the high side and 5" on the low side. I need to backfill it but not sure which way to proceed???
We have pretty cold winters here and I'm worried about frost heave if I just backfill dirt up against the pool.
Do I do a slurry mix and if so what is the ratio? like 1 80lb bag or concrete mix to how much sand, etc?
or do i just go straight up dirt for the backfill?
