Intent 1:

To limit the probability of inadequate resistance to or protection from surface water or water from the ground transferred by capillary action through masonry or concrete, which could lead to wood decay, which could lead to an inability to resist expected gravity or lateral loads.

For floors and elements supporting floors, this is to limit the probability of:

• compromised structural integrity, or
• where members support or are part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to deterioration.

This to limit the probability of excessive deflection or vibration of floors, which could lead to persons losing their balance, tripping or falling, which could lead to harm to persons.
