Installation of materials and components to provide
the required resistance to moisture transfer from the ground into or through building
assemblies, and through interfaces between assemblies, where such installation is within the application of the standards listed.
To limit the probability that the performance of the installed
material, with respect to resistance to moisture transfer, will fall significantly
below expectations, which could lead to moisture ingress from the ground.
This is to limit the probability of 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.
