The graders were here yesterday and did the grading. I have a sloped back yard. On one side of the pool the yard will be about 2 feet high maybe a couple inches more. They will be here on monday to install the pool. If they install the pool real close to that high side i think water will go down in there and wash sand away. And how will i back fill if its so close to that high side? When i backfill do i just put the dirt around the bottom of the pool about 6 inches high? Im in NC the dirt is pretty much clay.
