Description
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 levels). 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 of 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. A screen is attached to the top of the pipe to keep out animals and foreign objects. There are several other approaches to reducing radon levels. This is the approach we take for most of our installations. The interior system is aesthetically pleasing and the fan is not exposed to the elements. In colder climates freezing is not an issue. We have over 30 years of experience in finish carpentry and building construction. You simply cannot get a better system installation.
