Intent

Intent 1:

To limit the probability that such concrete blocks will be of inadequate mass or absorb excessive amounts of water, which could lead to inadequate resistance to freeze-thaw stresses.

This is to limit the probability of compromised structural integrity, which could lead to:

  • the structural failure of masonry construction,
  • where masonry construction is part of an environmental separator, the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration, which could lead to further compromised structural integrity, or
  • in assemblies exposed to moisture or the exterior, damage and deterioration, which could lead to further compromised structural integrity.

This is to limit the probability of harm to persons.
