Applicability:
Any house with a concrete slab floor on the
lowest level (basement or first floor) where the primary radon
source is below the house (virtually all houses with elevated
radon level).
Principle of Operation:
A negative pressure field is created below
the slab preventing the entry of radon gas into the house.
System Description:
One or more penetrations are made in the
slab and a small pit is created beneath each penetration. PVC
duct pipe is connected to the slab penetration(s) and routed to
the suction side of the fan. PVC pipe is then connected to the
pressure side of the fan and routed up the sidewall of the house
to discharge the radon gas safely above the roof. A weatherproof
electrical connection is provided for the fan.
