Radon Gas Mitigation Photo Album: Lowering Unsafe Radon Levels in Home in Londonderry, NH

In Londonderry, NH, a homeowner faced radon levels of 34 picocuries per liter, posing serious health concerns. Notice in the photos how our team at Erickson Foundation Solutions tackled this with precision. We installed a comprehensive radon mitigation system, including a radon fan and two extraction points, effectively reducing radon levels. Additionally, we upgraded an existing passive system with a new radon fan. Our skilled approach showcases our commitment to delivering permanent and reliable solutions to ensure a healthier living environment.

Radon Extraction Point

We initiated the project by creating an extraction point through the basement floor to depressurize the radon gas beneath the slab. A PVC pipe was then installed at the extraction point to safely channel radon gas away from the home's foundation.

Additional Radon Extraction Point

Given the elevated radon levels, an additional extraction point was necessary to ensure effective mitigation. The PVC pipes from both extraction points were merged and routed through the home's siding, facilitating the safe removal of radon gas from the basement.

Radon Extraction Point of Existing system

This is the extraction point of the existing radon mitigation system in the home. It operates as a passive system, meaning the PVC pipe lacks a radon fan to actively draw radon from the soil. The pipe is routed through the interior of the home and exits through the attic's roof.

Radon Fan

Upon reaching the exterior of the home, the PVC pipe was integrated with the radon mitigation fan. This fan actively extracts radon gas from the soil beneath the foundation, ensuring effective mitigation.

Radon Released Above Roofline

Additional piping is connected to the radon fan, extending beyond the roofline. This configuration ensures the safe expulsion of radon gas, effectively preventing it from entering any points within the home.

Radon Fan Installed to Passive System

We integrated a radon fan into the passive system, thereby converting it into an active radon mitigation system.

Foundation Crack Sealing

NexusPro was applied to all foundation cracks and floor joints. This advanced crack sealant provides an additional layer of protection, effectively preventing radon gas from seeping into the basement.
