Passive radon mitigation systems are a recently required option for new construction. They are similar to active systems, but do not include a fan. They operate under the assumption that the radon will naturally vent upwards through the piping, since it is easier that pushing through the concrete floor. If passive radon mitigation does not reduce the radon to the desired levels, a fan can be added to the system later.
Due to Illinois state law, passive radon mitigation systems are only installed during new construction, because it is difficult to test radon before the building is built. Research shows that these systems can reduce radon levels, but about 70% of them still need a fan added to cope with high radon. Adding a fan later is called “activating a system”.

Passive Radon Mitigation Systems
Installing a passive system is similar to installing a active system, except no fan or electricity is installed. In new construction, sometimes the concrete floor is poured around the suction point instead of coring a hole. Many of the same regulations apply to passive systems as to active systems.

“Dave and Larry did a great job installing our mitigation system and new sump pump. They were friendly, informative, and professional throughout the entire process. They explained both systems’ operation and answered all our questions. Afterward, the work location was cleaned up nicely. Excellent job.”

“Installation was good. They explained various factors as it progressed and they were finished under the time estimate. Results from the test were excellent.”
