Wet basements and wet crawl spaces present problems for the entire building. The key to improving basement moisture is controlling relative humidity.
Moisture vapor rises from dirt floors, on convection driven air-flow, to upper levels. Water that has penetrated foundations will also increase relative humidity and affect the entire building. Basement waterproofing with quality materials will prevent moisture from penetrating encapsulation and increasing humidity.
Elevated humidity increases moisture content in wood building materials. Wet organic building materials (wood, plywood, joists, beams, sills, sill plates, etc.) provide an environment necessary for mold growth. Dry basements and solutions to control wet basements and crawl spaces are fundamental in improving indoor air quality. Healthy indoor air quality begins in the basement or crawl space and moves upward.
