Interior Sub-Slab Depressurization Installations are installed inside of homes or businesses usually to keep the system inconspicuous or not visible from the exterior of the establishment.

The system works by creating a negative pressure under the home. The radon fan that has been installed in the attic of the home or building runs continuously in order for the system to work correctly to mitigate the radon from the home or building. From the radon collection point under the slab in the building’s foundation, the radon gas is collected, drawn from the collection point via the system’s fan, routed through the PVC piping installed in the attic and out of the home via the roof stack installed in the roof of the building.
