Don't Close the Walls Before You Read This: Ensuring Proper Radon Mitigation in New Construction

When building a new home, ensuring that every system is up to code isn't just about following regulations—it's about safeguarding the future. In recent months at Apex Radon Solutions, we've encountered several new constructions where the passive radon systems were improperly installed. Some of the misinstalls we’ve seen include: the radon fan being activated without knowledge of radon levels, the ventilation pipe being capped in the basement instead of extending through the home and out the roof, no electrical hookup in the attic for fan activation, and pipes installed so close to the roofline that adding a radon fan would be impossible. This oversight can lead to significant health risks and financial headaches down the line.

Understanding RRNC Standards 

RRNC, or Radon-Resistant New Construction, outlines the minimum requirements for passive radon mitigation systems in new homes. These standards are designed not just to comply with today's building codes but to ensure your home remains safe and sellable tomorrow. Key elements of a standard RRNC setup include:

• A 4-inch layer of gravel beneath the foundation for better gas movement.

• A polyethylene liner over this layer to prevent radon entry.

• A 3-inch PVC ventilation pipe that extends from the foundation below all the way up through the roof.

• An electrical outlet in the attic near the pipe's end, ready to power a fan if radon levels exceed the safe threshold.

Why Radon Testing is Crucial 

After your certificate of occupancy is granted, test for radon immediately to determine if the passive system should be activated. If radon levels are found to exceed the World Health Organization (WHO)-recommended action level of 2.7 pCi/L, mitigation is advised to ensure safety. If high levels are detected, activating the system can be as simple as adding a fan to the pre-installed pipe.
