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).
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 is routed to the
suction side of the Fan. PVC
pipe is then connected to the pressure side of the Fan and is routed up
the sidewall of the house to discharge the Radon Gas safely above the
roofline. A weatherproof electrical connection with switch is provided
for the fan. |
