How Water Gets in Your Crawl Space
After heavy rains, dirt-covered, open-vented crawl spaces easily allow moisture to seep up from the ground, and/or enter through your foundation walls through hydrostatic pressure. Because water can easily get under your home, often it will pool up and leave areas of standing water for days, or weeks at a time.
This can cause moisture issues, create a breeding ground for mold, attract unwanted pests, and, ultimately damage the structure of your home.
