9.35.3.2.(2)

Intent 1:

To limit the probability that frost-related soil movement beneath the adjacent slabs-on-ground will be transmitted, which could lead to excessive stresses, which could lead to the cracking of slabs-on-ground supporting attached buildings, which could lead to an inability to support vertical building loads.

This is to limit the probability of:

• structural failure, or
• compromised structural integrity of elements supported by the slab, which could lead to the failure of environmental separation elements, which could lead to the deterioration of building elements.

This is to limit the probability of harm to persons.
