Active Soil Depressurization
Effective + Efficient Way to Reduce Radon
Concept explained in 30 Sec.
Radon fan + piping venting system
A venting system penetrated below the concrete slab to suck air, soil + radon gas from under the house and exhaust to outdoor.
As air being suck out, air pressure under the house becomes lower than inside the basement. This is what we mean "soil depressurization".
The radon and soil gas choose the less resistance path and flow through the venting system rather than squeezing through the basement cracks / gap to enter into the basement.
Less radon entry
