Re: Exterior Perimeter Drain Observation

Terracon Project No. 20005162
Gentlemen:
A representative of Terracon observed the perimeter drain at the referenced site on September 16,
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 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 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,
TERRACON
