A representative of Terracon observed the perimeter drain at the referenced site on March 10,
2003, 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 pit located within the basement area.
We also observed 3/ to 1-inch washed gravel placed above and below the pipe and drainage filter
fabric placed 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, .
