A crawl space is often the top culprit in allowing radon into our homes. It’s not like a full basement with a concrete floor. It’s often left as exposed dirt, or sometimes lined with gravel. These don’t stop radon in any way. High radon levels in your house can be significantly reduced with crawl space encapsulation. The key is to create a barrier that doesn’t allow the radon to enter the crawl space itself. Additional barriers and fans are also put into place to ensure that the radon gets properly vented out of your home or business. As an added bonus, crawl space encapsulation has been known to reduce allergy issues, by reducing mold and ventilating it from your home.
Here are some images to better demonstrate crawl space encapsulation.
