Facts:
1) 95% of construction litigation is the result of
water intrusion.
2) 90% of all water intrusion problems occur
within 1% of the structure’s exterior surface
area.
3) 95% of all water leaks are attributable to
causes other than material or system
failures.
While individual waterproofing materials and
systems continue to improve, no one is
improving the necessary, and often critical,
detailing that is required to transition from one
building component to the next. Furthermore, we
seem to move further away from the superior
results achieved by applying basic waterproofing
principles, such as maximizing roof slopes, to
achieve desired aesthetic values instead. There is
no reason that aesthetics cannot be fully
integrated with sound waterproofing guidelines.
It is up to the industry to acknowledge these
shortcomings and to resolve water intrusion
problems at the job site rather than in the
courtroom.
