Sentence 9.16.2.2.(2)

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 excessive deflection, which could lead to persons losing their balance, tripping or falling, which could lead to harm to persons.
