Intent 1:
To limit the probability that an inadequate resistance
to sulphate salts in the soil will lead to the inadequate performance
or the premature failure of concrete under expected environmental
or structural loads.
This is to limit the probability
of:
- compromised structural integrity, or
- where concrete supports or is used in an environmental
separator, the displacement or failure of required environmental separation
elements, which could lead to the deterioration of building elements,
which could lead to compromised structural integrity.
This is to limit the probability of:
- uneven concrete floor or step surfaces, which could
lead to persons tripping,
- the failure of supported handrails or guards, which
could lead to persons falling,
- the excessive deflection or vibration of supported wood-frame
floors, which could lead to persons losing their balance, tripping
or falling, and
- the failure of fireplaces or chimneys, which could lead
to the leakage of combustion products, including carbon monoxide gas,
into living space, which could lead to the asphyxiation or acute poisoning
of persons.
This is to limit the probability of harm to persons.
