Design and construction of materials and components installed to provide the required protection from moisture transfer from the ground into or through building assemblies, and through interfaces between 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].
Exceptions:

  • Sentence 5.8.2.2.(7), which applies to assemblies that:
    • are constructed of cast-in-place concrete,
