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, which could lead to:
- structural failure,
- 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, or
- an inability to resist expected loads, which could lead
to
- the excessive deformation or deflection of walls, or
- the excessive deflection or vibration of floors.
This is to limit the probability of:
- the space being unsuitable for its intended use, or
- damage to the building.
