5.8.2.2.(7)


Objective	OS2 Structural Safety
Attribution	(b) [F61-OS2.3]
Application	Application 1: Dampproofing materials, within the application of the standards listed, installed to provide resistance to moisture transfer from the ground into or through building assemblies, and through interfaces between assemblies, that: are constructed of cast-in-place concrete, have a drainage layer installed between the assembly and the soil to reduce moisture loading, and are not exposed to hydrostatic pressure. This applies to building materials, components or assemblies and their interfaces described in Sentence 5.1.2.1.(1) that are installed in buildings to which Part 5 applies [see Sentence 1.3.3.2.(1) of Division A for application of Part 5]. Exceptions: except as stated in Sentence 5.8.2.1.(2), which applies where a lack of resistance to moisture transfer from the ground will not adversely affect health, safety, the intended use of the building or the operation of building services.

Intent	Intent 1: To limit the probability that the performance of the installed dampproofing material, with respect to resistance to moisture transfer, will fall significantly below expectations, 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. This is to limit the probability of structural failure, which could lead to harm to persons.
