IV. Inspector Comments
V. PHOTOGRAPHS
Photo 1: View of Townhome development facing north.
The VIMS barrier installation looked good, with only a couple of areas identified that
required additional taping. During the inspection, it was observed that a significant
amount of the tape utilized on Building 4 was manufactured by Stego Wrap and it was
being used with a competitor’s vapor barrier – VaporBlock VB-20 (Photos 2-5). The
project engineer was out of the office; however, I spoke with Andrew Besu with H&H and
the project engineer had contacted both barrier manufacturers to confirm this was not
an issue. It was determined that even though Stego Industries would not warranty the
work, it would meet the manufacturers specifications and the developer was willing to
accept the loss of the manufacturer’s warranty. Following an internal DEQ discussion, it
was determined this was acceptable with the Design Engineers sign-off.
