[F21-OH4]
Applies to foundations that support
floors and other elements that support floors.
|
Application | Application 1: Foundations located in
areas where soil movement caused by changes in soil moisture content, freezing, or chemical-microbiological
oxidation is known to occur to the extent that it will damage a building to
which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application
of Part 9]. |

Intent | Intent 1: To limit the probability that moisture-content-related soil
movement, frost heave, pressure due to the formation of ice lenses, adfreeze,
and weathering of pyritic material will lead to the cracking of foundations
or building superstructures. This is to limit the probability
of:
For floors and elements supporting floors, this is to limit the
probability of excessive movement, deflection or vibration of floors, which
