Soil is a cancer-causing natural radioactive gas that you can't see, smell or taste. Its presence in your home can pose a danger to your family's health. 

Soil gas to some degree is present in every home. An estimated one out of every 15 homes in the United States has soil levels above 4pci/L, the U. S. Environmental Protection Agency-recommended action level. Soil, a naturally occurring gas, can enter the home through cracks in the foundation floor and walls, drains, your crawl space, and other openings. Indoor soil exposure is estimated to be the second leading cause of lung cancer. A recent report by the National Research Council estimates that soil is responsible for between 15,000 and 21,000 lung cancer deaths each year in the United States. 

How System eliminates soil gas 

The CrawlSpace Guys Crawl Space Sealing System uses a specialized soil gas vapor barrier that prevents soil gas from entering your home from your crawl space. Coupled with a ventilation system, this radioactive gas is directed to vent harmlessly into the earth's atmosphere. 

By completely sealing your crawl space and directing all ground gases and other pollutants away from your breathable air, the CrawlSpace Guys System will greatly improve the air quality throughout your home, providing a cost-effective, permanent solution to allergens and irritants by eliminating the source of the problem while creating a clean, dry, sanitary storage area and protecting the value of your home.
