What are some of the radon mitigation methods?
There are several mitigation methods available: • Active slab depressurization is the most common and reliable method. In this technique, pipes are inserted through the floor slab. A fan is connected to the pipe, which then suctions radon and other gases before these enter the home. • Sub-membrane depressurization is similar to the active slap depressurization, and is used in crawl spaces. • Sealing cracks and other openings in the foundation may limit the flow of radon gas into the home. But sealing alone may not be sufficient to reduce radon levels consistently. • Building pressurization uses a fan to blow air into the structure to create enough pressure and prevent radon from entering a home. This method may be less energy efficient and is limited by the house construction, climate, and occupant life styles.
