A block wall suction system is comprised of a fan and ductwork, both of which suction radon gas through the hollow cavities of cinder block walls. This mitigation strategy depends on maintaining a lower air pressure inside of the hollow cavity than exists in the basement, where piping and your suction point will be installed. The difference in air pressure should pull radon gas from the soil and remove it from the building before it can even enter.

One huge benefit of using a block wall depressurization system is that, unlike some of the other mitigation options, it both removes radon and prevents it from reentering the building later.

Although block wall depressurization systems won’t work for every building, they’re an effective radon mitigation solution for those with the proper foundation. It’s also worth noting that installing this type of system will require contractors to seal all openings for it to properly function.
