|
BGS Radon Mitigations provides professional, experienced,
and qualified radon remediation services and systems. A full
range of passive and/or active radon mitigation systems is
provided to lower radon levels in buildings configured as
slab-on-grade, basement, crawl space, or a combination design.
The installed systems are designed to be as unobtrusive and
aesthetically binding with the structure as possible.

Outdoor Installation
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.

Indoor Installation
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
unobtrusively (through closets, plumbing
chases or other unexposed areas) to the
suction side of the fan. PVC pipe is then
connected to the pressure side of the fan
and routed through the roof using a standard
roof flange and waterproof sealants. The
radon gas is discharged safely above the
roof The PVC vent pipe protrudes slightly
above the roof and has the same
appearance as a standard plumbing vent
pipe.
