A representative of Terracon observed the perimeter drain construction at the referenced site on
August 2, 2002, as requested. A four -inch diameter perforated PVC pipe had been placed around
the exterior perimeter of the basement foundation. The drainage pipe appeared to exhibit positive
drainage toward the sump pump located within the basement area. We also observed 1% inch
washed gravel placed above and below the pipe and drainage filter fabric above the gravel. The
waterproof dampening of the foundation system was also observed and in our opinion was
completed in general accordance with standard residential practices.
In our opinion the exterior perimeter drain was constructed in general accordance with the plans and
specifications for this project.
Sincerely,
TERRACON
