Radon-Resistant New Construction is the practice of installing a passive radon mitigation system during the construction of a new home or structure. A passive radon system utilizes the natural pressure differential in your home to move radon through the vent pipe and out of your home. After home construction is complete and the structure is occupied, it is important to conduct a radon test. If the radon test yields results above the 4.0 pCi/L action level, you should activate your pre-piped radon system by installing a contractor grade radon fan. The only difference between an active and passive active soil depressurization system (ASD system) is the presence of a radon fan.

There are many benefits to installing a passive radon mitigation system in a new construction. There is no reliable way to test the ground for radon before the structure is in place, if you are building a structure in an area known to have high radon, it is a good idea to include a passive radon system during construction. There are many resources available to determine if your area has high radon, such as this EPA Map of Radon Zones. The cost of installing an ASD system during construction is also much less than installing one after the fact. Building a radon system into the home during construction also helps to keep the aesthetics of the home intact, as the builder is much more free to hide and route piping appropriately.
In an occupied home, only the owner or a licensed radon mitigation professional can perform radon work. To ensure radon-resistant construction, while owned by the builders, they are permitted to install an ASD system without the required license. Although it is not required, it is recommended to seek out the assistance of a licensed radon professional to help avoid the complications and potential pitfalls of installing an effective radon mitigation system.
