Intent 1:
To limit the probability that soil movement resulting
from freezing of the soil will lead to the heaving or subsidence of
floors-on-ground, which could lead to:
- the failure of floors-on-ground, or
- the compromised structural integrity of floors-on-ground,
which could lead to the ingress of moisture from the ground, which
could lead to the deterioration of building elements.
This is to limit the probability of
damage to the building.
