Radon Gas Removal

Soil Suction

• The most common method used for removing radon is soil suction. In this method, suction pipes are placed into the soil beneath the concrete slab that the house sits on, either by drilling through the floor slab in the basement, or through the soil outside the house. A fan is connected to the pipes, and sucks the radon from the soil and releases it into the air around the house. Soil suction is usually the most reliable method for removing radon.

Pressurization

• In pressurization, a fan blows air from the upstairs or outside into the basement, with the idea being that it will create enough air pressure in the basement that radon won't be able to seep in. The construction of your house may limit the effectiveness of pressurization, as doors and windows need to be left closed so that air pressure can build up in the lowest level of the house. One major downside is that the outside air being drawn in can lead to moisture problems and increase your heating/cooling bills.

Sealing and Ventilation

• Sealing cracks in your foundation can help prevent radon from getting into your home in the first place, but the EPA doesn't recommend using this as a stand-alone solution to your radon problem. So in addition to sealing cracks in the foundation, you should also ventilate your basement. You can do this by installing a fan in your basement that will draw radon-filled basement air through a duct and outside your house, where it will be released.
