The thin veneers for the outside seem to be more and more common. How do most of these applications hold up over time? I would think they would need to be completely moisture proof to keep moisture getting in and freezing causing problems already seen with some old masonry work. Like using a sealer ever few years.
Looking at one where the brick chimney cap failure has caused much spalling, someone mentioned to them about going right over the existing brick chimney with thin brick or stone, then use a new cap of some sort.
I would think the potential problems here would be amplified if moisture got behind.
What do you guys suggest or think of these masonry systems?
