I am in the process of having a pool installed and some aspects of the install have me concerned.
This is a 34' fiberglass pool. Once the concrete was poured, it became clear that the waterline is off by up to two inches from the lowest point to the highest. While this is not ideal, more concerning is how the concrete was poured to account for this. Basically, below the smoothed curve coping of the concrete pool, an additional 1.5 to 2inches of rough aggregate which was poured in order to ensure that the concrete deck was level. This 1.5-2 inches is present for probably 85% of the edging of the pool.
The pool installer says that that rough concrete and the lack of 'level-ness' will not be an issue because they will just tile over the concrete as well as the fiberglass. I question this only because I understood the tile to be installed directly on the fiberglass and not on the concrete. Additionally, it seems like the tile will not be laid on a flat surface (especially given the exposed aggregate). And I feel that you'd use a different adhesive on concrete as opposed to fiberglass.
I worry that they'll install the tile and it will look reasonable. But 6 months from now, they will all pop off.
Of course, I know nothing about pools or concrete or tiling. So, maybe I should just trust the experts. But, as a double-check, i thought I'd post here to get a third party perspective. Thanks so much for any advice!
