9.12.3.3.(1)

Intent 1:

To limit the probability of inappropriate backfill material, which could lead to point loads being applied to foundation walls by boulders in the backfill under lateral soil pressure, which could lead to:

• the cracking of foundation walls, or
• damage to a foundation's moisture-control elements.

This is to limit the probability of compromised structural integrity of elements supported by foundations, which could lead to:

• an inability to support vertical building loads or lateral earth loads, or
• for environmental separators or elements supporting an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements.

This is to limit the probability of harm to persons.
