How to: Prevent Moisture Intrusion

Water infiltration caused by improper exterior drainage is a leading contributor to indoor mold growth. Follow these US Environmental Protection Agency (EPA) guidelines to help keep rain and surface water out of your home.

1.     Ensure a minimum of 8 inches of the foundation is exposed above the surrounding foundation grade.

2.     Divert water away from the foundation by grading the 10-foot area immediately adjacent to the foundation with a minimum 5% slope (6-inch drop per 10-foot extension).

3.     Redirect water away from the building by grading proximate lawns and gardens with a minimum 2% slope (2.4-inch drop per 10-foot extension).
