ATTRIBUTION:

Functional Statement:

F61

To resist the ingress of precipitation, water or moisture from the exterior or from the ground.

Objective:

OS2.3

 

APPLICATION:

Construction, control or expansion joints, in building assemblies that separate interior space from the ground, in buildings to which Part 5 applies [see Sentence 1.3.3.2.(1) of Division A for application of Part 5].

INTENT:

To limit the probability of inadequate detailing and sealing of joints, which could lead to discontinuity of protection at joints, which could lead to moisture ingress from the ground, which could lead to deterioration, which could lead to compromised structural integrity of the separators or of elements supported or protected by the separators, which could lead to structural failure, which could lead to harm to persons.

APPLICATION:

Construction, control or expansion joints, in building assemblies that separate interior space from the ground, in buildings to which Part 5 applies [see Sentence 1.3.3.2.(1) of Division A for application of Part 5].

INTENT:

To limit the probability of inadequate detailing and sealing of joints, which could lead to discontinuity of protection at joints, which could lead to moisture ingress from the ground.
This is to limit the probability of:
  • the inadequate control of relative humidity or water accumulation,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity of environmental separators.
This is to limit the probability of:
  • negative effects on the air quality of indoor spaces,
  • the inadequate thermal comfort of persons, and
  • contact with moisture.
This is to limit the probability of harm to persons.
