Intent

Intent 1:

To limit the probability of inadequate compressive or bond strength, which could lead to:

  • cracking of mortar joints and grout,
  • inadequate bonding of mortar with masonry units, or
  • inadequate bonding of grout with masonry units and reinforcing steel.

This is to limit the probability of:

  • compromised structural integrity of masonry construction,
  • where masonry construction is part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to deterioration,
  • in assemblies exposed to moisture or the exterior, damage and deterioration, or
  • an inability to resist expected loads, which could lead to excessive deflection or vibration of floors.

For floors and elements supporting floors, this is to limit the probability of persons losing their balance, tripping or falling, which could lead to harm to persons.
