What is radon resistant construction?
Radon – resistant construction techniques comprise a “passive” radon system. This system overcomes the vacuum effect experienced by most houses by creating a pressure barrier to radon entry. The system also includes a pipe to vent radon gas safely to the outdoors.
Is builder responsible for radon?
