9.25.2.3.(5)

Intent 1:

To limit the probability that insufficient heat will reach the soil around foundations, which could lead to the freezing of soil, which could lead to frost-related soil movement, which could lead to cracking of footings, slabs-on-ground or building envelope assemblies supported by footings or slabs-on-ground.

This is to limit the probability of :

• the structural failure of footings and slabs-on-ground, or
• condensation, precipitation ingress or the ingress of moisture from the ground, which could lead to deterioration, which could lead to compromised structural integrity of supported assemblies acting as or protected by environmental separators.

This is to limit the probability of harm to persons.
