i have installed approximately 1000 systems most of which had several drops or single drops (meaning holes cut through the cement floor slab of concrete with each
pipe sealed with the grey 20 year silicon) ....then it travels up.... on an angle
to the up-stack pipe to the radon fan (installed in a non living space) and stays on 365 days a year exhausting the radon gas out through the roof.
~
we used 4" diamond studded hole saw cutting through tile or concrete... then you dig out some "under the slab material" (dirt and or gravel) so you have a
good draw from underneath the cellar floor...
~
the under the slab material determines how powerful a fan you need depending on what it is...how dense, or coarse.... and what the initial radon test showed...
~
the 4" stubby trick is used when you only need a "small adjustment"
to let some needed air in... to a fairly air tight basement.
...........
technically unless your house is built on top of
shale rock , Radon gas is usually -> not a major concern.
there's allot of unscrupulous stuff that goes on with radon testing.... some guys would go down to the basement with an empty jar....right... and swim it
back and forth as if to capture some air then claim to go have it tested for what ever they could get away with charging....
