So we have a L shaped wall that is 4' high on one side and goes down to grade on the shorter side. The pool installer is going to put in linear drains around the pool deck I'm assuming to keep mostly rain water away. I have also seen pictures of pool decks that have walls were there is a gap between the wall and the deck (cement) that has rocks of some kind filling that gap.
I have two thoughts on both of these: 1) if the concrete goes all the way to the wall if the wall shifts/settles that could crack the concrete. 2) If there is a gap between the two that separates them allowing movement, the drain can be put under the rocks.
Is this more of a personal choice or is there any merit to what I'm thinking? I'm sure I'm overthinking this whole idea.
