Sealing the crawl space with an encapsulation system can combat many issues including moisture, mold, mildew, musty odors, critters, and wood rot. However, even the heaviest liners do not offer protection against Volatile Organic Compounds (VOCs) such as radon, benzene, contaminated groundwater, and dangerous soil vapor.

Exposure to these contaminants can put you and your family’s health at risk. Short-term exposure to high levels of organic vapors can cause eye and respiratory irritation, headache or nausea. Breathing low levels of organic vapors over a long period of time may increase an individual’s risk for respiratory ailments, cancer and other health problems.
