Intent
Intent 1: 
To limit the probability of an inadequate substrate, which could lead to discontinuity in the dampproofing, which could lead to an inadequate resistance to moisture transfer from the ground, which could lead to the ingress of moisture from the ground, which could lead to deterioration, which could lead to compromised structural integrity of elements supported or protected by the walls, which could lead to harm to persons.
Intent 2: 
To expand the application of Subsection 9.20.3. to include parging on masonry below ground that is used as a dampproofing substrate.
