Dirt or crawl space floors inside the home transmit humidity, odors and radon gas. They may provide rodents and insects an easy path into the upper living portions of the home. The humidity and dampness that is inherent in a crawlspace may also cause structural damage to the wood framing, carpets, floors and walls. This environment is a breeding ground for mold and mildew, all of which present a real problem. The homeowner might consider pouring concrete over the wet crawlspace floor, but in a post construction setting, this is often unrealistic and impractical. The best method is to use proper crawl space encapsulation techniques using a crawl space vapor barrier and a drawl space dehumidifier.
