Passive radon mitigation systems can save lives. When properly installed, passive radon mitigation systems can keep radon levels down without the assistance of a radon fan. New construction homes can be built radon resistant with a permanently installed passive radon system.
Although codes vary from town to town, there are six basic components of radon resistant new construction techniques:
It is important to use a radon mitigation contractor when using radon resistant new construction techniques. Radon contractors know how to properly move the air below the building. In many areas, plumbers are used to install passive radon systems. Often we have found that the suction point is placed in the gravel and the concrete has created a seal around the radon suction point location. This is dangerous because the homeowner is under the impression that the home is built radon resistant yet the passive radon pipe cannot move any air. If you have a home with a passive system, be certain to perform a radon test at least every two years.
In the event radon levels remain elevated with after radon-resistant techniques have been used, the passive radon system can easily be converted to an active soil depressurization system (active radon system). This can be done by adding a radon fan to the radon vent pipe in the attic space above the home or building.
