Intent 1:
To limit the probability of insufficient contact
area between mortar and masonry veneer, which could lead to:
- the wall being unable to support its own weight or lateral
loads,
- insufficient bonding area between ties and mortar, or
- insufficient bond strength between masonry units.
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:
- the excessive movement or deformation of walls, or
- the excessive deflection or vibration of floors.
This is to limit the probability of:
- the space being unsuitable for its intended use,
- compromised operation of windows or doors, or
- damage to the building.
