I want to put 2" thick limestone "caps" or slabs on top of the concrete block wall of my deck to finish it off. The deck will be covered with a roof and the walls will be finished off as well. The deck is going to be built over a room in my basement. I am concerned about water and my question is this: How pourous is limestone and, if it is, how can I seal it?
