Roof Top Swimming Pool

[mijowe]

I have a roof top swimming pool where i am providing a structural tub to support all loads induced by the pool. I am then showing a pool shell by others, assumed to be gunite. If the shell is not to experiences any stress, what is the minimum thickness it can be? I have a pool guy telling me he wants 8" min for walls and slab. I see that as required thickness when the shell is structural, and would anticipate a thinner wall if it can bear directly on my structure.

If you are providing the primary structure for the bottom and the sides, aren’t there rubber, plastic, and the like, type liners which are just more or less glued to your structure? They will also tolerate a little structural movement without cracking.

I did an elevated pool where the pool consultant insisted on a thick layer of gunnite (I think it was 8"). This was non-structural inside of the structural concrete shell. We debated it for a while, but ultimately, the 8" gunnite is how it ended up.
