Came home for lunch today and the crew was prepping and starting to lay waterline tile. Also installed the skimmer. Talked to the head dude, who has lots of experience and seemed pretty knowledgeable. Install looks nice and clean and we are pleased with the color we picked. Walked around the pool and there's an area where the waterline tile is doubled stacked. The weird thing is that the top half of the tile goes much higher than the gunite (see pics). They put a bunch of thinset behind it. I don't know much about tiling but it just seems weird to me that they did it like this. What is going to happen when the coping goes in? Do they pour more concrete to bring up the edge of the pool? Do they cut the tile?
