Intent 1:
To limit the probability that:
- the performance of bituminous dampproofing materials
will fall significantly below expectations with respect to moisture
transfer resistance, or
- the performance of polyethylene used as dampproofing
will fall significantly below expectations with respect to
- moisture transfer resistance, or
- strength, flexibility, and resistance to tearing, puncturing,
oxidation or ultraviolet radiation, which could lead to damage during
installation.
This is to limit the probability of
an inadequate resistance to moisture transfer from the ground, which
could lead to the ingress of moisture from the ground, which could
lead to deterioration, which could lead to compromised structural
integrity of elements supported or protected by foundation walls or
floors, which could lead to harm to persons.
