A representative of Terracon observed the perimeter drain at the referenced site on February 18,
2003, as requested. A four -inch diameter perforated PVC pipe had been placed around the exterior
perimeter of the basement foundation with an impervious PVC membrane beneath the drainage
system. The drainage pipe appeared to exhibit positive drainage toward the sump pit located within
the basement area. We also observed 1 %2 inch washed gravel placed above and below the pipe
and drainage filter fabric above the gravel. The waterproof dampening was also observed and in our
opinion was uniformly applied to the exterior foundations.
In our opinion the exterior perimeter drain was constructed in general accordance with the plans and
specifications for this project.
Sincerely,
