Dirt Crawl Spaces

The main issue with dirt crawl spaces is the moisture from the dirt beneath the home. Whether your crawl space suffers from groundwater leakage or not, water vapor from the ground evaporates and moves upward into your home. This can lead to rotted floor joists, mold growth and poor indoor air quality.

Generally, dirt crawl spaces are constructed to be cost effective. As homeowners have since realized by having a dirt crawl space they are leaving the property vulnerable to moisture. By not guarding their home from the effects of ground water and the exchange of exterior air into the crawl space they are allowing the moisture from either source to be detrimental to the property. Insulation once damp dramatically decreases its effectiveness and allowing fungal growth to occur. Fungal growth if left untreated, will start the process of decay and root to wood materials resulting in structural damage.

A solid, continuous vapor barrier (vapor diffusion retarder) provides protection for the crawl space emulating a miniature basement. Just as siding, sheathing and insulation separate the home from outside contaminates like moisture and pests, crawl spaces should be treated exactly the same. Vapor barriers are non-permeable, stopping moisture from coming in contact with wood and other service equipment in the crawl space.
