Oh my gosh, the saga continues! We finally got the pool structure up and are getting ready to cut the 1.5" styrofoam for beneath the liner, but nothing is working out to level. We used a laser transit the WHOLE time for leveling and my husband also used a level stick to level the whole time we were constructing the pool. Also, my husband builds large buildings for a living so he's not new to constructing things. SO WHY IS EVERYTHING OFF? Here are some pictures, and I will comment with questions under each one:

Here is a picture of how off level the ONE SIDE of the pool is. The other side is perfectly level (and the whole daggone thing is hooked together so how can this be?)

Here is a picture of the one corner of our pool that is not exactly to grade. We used a 4" block so most of the block is buried, but some is not and you can see the difference. Is this ok?

Here is the rest of the side I just showed you so you can see how flush with the ground the rest of it is.

Here is the MAIN question........the directions said we needed a 7.6 foot radius for the oval part of the pool. We sprayed the radius and also drove rebar stakes into the ground around that radius. When we put the wall channel up and then put the wall into it, in order for the wall ends to meet up and overlap, we had to squeeze it together which shortened the radius. We are trying to cut foam to fit the inside. Is the weight of the water going to shift this and will there be a gap between the foam and the sides? We are so frustrated. Nothing is going right.

I'm sorry this is so long!
