A representative of Terracon observed the perimeter drain construction at the referenced
site on July 22, 2002, as requested. A four -inch diameter perforated PVC pipe underlain by
a PVC impervious liner material 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 3/-inch washed gravel
placed above and below the pipe and drainage filter fabric placed 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,
