9.12.1.3.(1)

Intent 1:

To limit the probability of ice lens formation beneath foundations that are installed on fine-grained soils (which can retain quite a bit of water), which could lead to the excessive vertical movement of the soil, which could lead to excessive stress on foundations, which could lead to structural damage to foundations and superstructures.

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.
