How is Radon Gas Removed?

Radon in Air

Radon, one of the six "Noble" gasses, is an "inert" gas.  Typically motionless, it is solely driven, to one direction or another, by pressure (positive or negative) and has absolutely no static charge, so, it does not react or stick to other things. This is why conventional methods of air filtration, even the best HEPA filtration systems, are not effective for radon removal from the air in your home. There are basically three ways to deal with radon, that is entering the building from beneath a ground-level slab or basement concrete floor: (1) Try to seal it out, which, in most cases, is extremely difficult.  (2) Suck it out from beneath the building, before it enters the occupied space (3) Treat it after it enters the structure by means of ventilation or continuous indoor air exchange.


The most popular and effective method is to "Suck It Out", which is also known as "Active Sub-Slab Depressurization." A  PVC pipe is inserted into the concrete slab in a strategic spot. The vent pipe is then routed either externally, on the outside of the building, or internally through the building, if the floor plan permits. The system is powered by an "industry specific" fan that is specifically designed to draw out the radon gas from underneath the concrete floor in the basement and route it above the roof edge of the house, where the gas can dissipate safely into the atmosphere. These fans must be installed according to industry standards and protocols to prevent radon gas from re-entering the home


The radon removal systems we install for our customers often exceed industry standards, and guarantees that the average indoor radon gas level will be below 4 pCi/L.
