Sentence 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:

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

For floors and elements supporting floors, this is to limit the probability of excessive deflection and vibration, which could lead to persons losing their balance, tripping or falling, which could lead to harm to persons.
