How would one avoid putting dents and cuts in the polystyrene foam when getting the walls of the pool in the track? When we did a dry run before the foam and it was just level clay/sand it went pretty easily. I didn't use any plywood to sit the wall on it seemed to be harder to use plywood. We placed the metal wall in a roll in the center and just inched it out. The walls were actually seamed together galled or rusted at the seam. I was able to detach the edges. I have a photo. I hope it works.
My thought was to have 3 people and maybe some T post to secure the wall too. Unroll the wall around the outside of the track and hop it into the track.
We went with the foam to help with heat retention, smoother bottom. We are praying for no wind. I have the foam weighted down. We live at high altitude and the sun gets too hot to continue this morning
Under the foam is think carpet and then a sand clay mix. All the patio blocks were leveled. A big trick will be positioning the vertical brackets over the patio blocks.
