First Filing 6344 Rookery Road B0706&93 Fort Collins, Colorado (Larimer County) Dear Mr. Phillips: On February 25, 2008 this office observed the foundation sub -drain materials installed around the exterior perimeter of the basement foundation. The sub -drain pipe is connected to a sump pit in the basement. The homeowner should check the sump pit periodically for water. If water accumulates in the pit, a licensed plumber should install a submersible pump with an automatic float switch. The pipe from the pit should discharge at an acceptable location away from all foundation walls and window wells and exterior concrete flatwork. At the time of this observation the foundation sub -drain materials appeared to be properly installed. We also observed the spray -on damp proofing applied to the exterior of the basement foundation walls. The damp proofing appears to adequately cover the basement foundation walls. Please note that spray -on damp proofing is typically effective for reducing moisture infiltration in the absence of hydrostatic pressure. Spray -on damp proofing does not create a waterproof barrier that is capable of resisting moisture infiltration under hydrostatic pressure. Thus it may be possible for water to infiltrate the foundation, particularly at form -tie penetrations and hairline cracks that sometimes occur from shrinkage, especially near basement window openings. It is important to provide and maintain drainage paths that allow all surface water to flow quickly away from all foundation walls, window wells and exterior concrete flatwork. Please refer to the enclosed photographs. If you have any questions, or if we may be of further service, please contact this office at your convenience.
