Intent
Intent 1: 
To limit the probability of inadequate protection from precipitation at vulnerable locations in masonry and masonry veneer walls, which could lead to precipitation or meltwater ingress.
This is to limit the probability of:
  • the deterioration of masonry due to freeze-thaw stresses, which could lead to masonry falling, or
  • the deterioration of elements inboard of the masonry, which could lead to compromised structural integrity, which could lead to structural collapse.
This is to limit the probability of harm to persons.
