Radon Gas Mitigation Photo Album: Sub Slab Depressurization System in Downingtown PA

A short term radon test was set up in this Downingtown, PA home for 48hours, once the 48hours was up, the test produced results showing the average level of radon in this home, was 12pCi/L. The type of system we ended up installing at this property is called a Sub Slab Depressurization System with an additional extraction point.  Once the system was in play, we then set up another 48hour test to see if we were able to reduce the levels of radon to be below the 4pCi/L.  After 48 hours, test was sent off to the lab for results, results came in and we were able to get the radon levels from 12pCi/L, down to 1.3pCi/L.    

Sub Slab Depressurization System

A Radon PVC pipe is installed directly into the slab and sealed off

Manometer

This is the best way to tell if the radon system is working. If the levels are ever even, this means there is no pressure and radon gas is no longer being pulled out of the home

Additional Extraction Point

An additional extraction point was created in connecting garage.

Radon Fan and Vent Pipe

Radon fan is installed on the exterior of the home and the radon vent pipe is installed above the roof line
