Water in a crawl space is very common. The bottom of the crawl space foundation is generally only 2-4’ deep. Since the foundation does not go down nearly as far into the ground as a basement foundation, it is much easier for moisture to penetrate the exterior soils and get down to the base of the foundation. Once water has reached the base of the foundation, water does what it does best. It finds the path of least resistance into your home. When a crawl space does not have a proper drainage system and vapor barrier, this water will saturate the soils under your home and in some cases, there is enough water to cause pooling and flooding. This water will contribute to odors, wood rot, mold, and can cause sinking of main supports. Water issues in a crawl space should always be treated immediately before they cause major issues in the home.
