Today is the day for installing coping for my inground gunite pool. The gunite was poured about two weeks ago. I purchased anchor sockets (for my removable ladder and removable spa rail) and ask the crew to install the anchors in the coping. The problem is the height of the anchor sockets (4.25") are more than the thickness of the coping, meaning that a part of it must go through the gunite which is about two weeks old. I would like to know if it will be any issue to make a hole in the gunite to make a part of anchor socket go through it?
