Radon Reduction Techniques and Systems
There are several methods RadonNC can use to lower radon levels in your home.
Some systems are designed to prevent radon from entering your home.
Other systems reduce radon gas that has already entered into the home.
Each radon mitigation system is custom designed specifically for each house's unique structure, foundation, environmental factors and air flow.

Foundation and House Types
RadonNC will perform visual inspection and/or diagnostic tests of your house and foundation in order to determine the most effective radon reduction system for your home.
Houses are generally categorized according to their foundation design. For example: basement, slab-on-grade (concrete poured at ground level), or crawlspace (a shallow unfinished space under the first floor). Some houses have more than one foundation design feature. No matter what type of foundation your house has, RadonNC guarantees their systems will maintain radon levels below 4 pCi/L.
Basement and Slab-on-Grade Houses
In houses that have a basement or a slab-on-grade foundation, radon is usually reduced by one of four types of soil suction: subslab suction, drain tile suction, sump hole suction, or block wall suction.
Active subslab suction (also called subslab depressurization) is the most common and usually the most reliable radon reduction method. A radon vent fan connected to the suction pipe(s) draws the radon gas from below the house and releases it into the outdoor air while simultaneously creating a vacuum beneath the slab. This type of system is also used in some townhomes.
Passive subslab suction is the same as active subslab suction except that it relies on natural pressure differentials and air currents instead of a fan to draw radon up from below the house.
Block wall suction can be used in basement houses with hollow block foundation walls. This method removes radon and depressurizes the block wall, similar to subslab suction. This method is often used in combination with subslab suction.

Crawlspace Houses
An effective method to reduce radon levels in crawlspace houses involves a form of soil suction is called submembrane suction. When properly installed, this is the most effective way to reduce radon levels in crawlspace houses.
In some cases, radon levels can be lowered by passive or active ventilation systems, which lower indoor radon levels by both reducing the home's suction on the soil and by diluting the radon beneath the house.
Condominiums and TownhomesTownhomes can have active subslab or ERV systems In houses that have a basement or a slab-on-grade foundation, radon is usually reduced by one of four types of soil suction: subslab suction, drain tile suction, sump hole suction, or block wall suction.
Energy recovery ventilator (ERV) systems are used in all condominiums and in some townhomes. Rather than bringing fresh air in from outside, some condominium and townhome HVAC systems recirculate the same stagnant air, thus trapping radon gas inside the home. The ERV system works in conjunction with a home's existing HVAC system to force stagnant air out of the home while drawing fresh air in. The ERV system is the most energy efficient and cost effective way to reduce radon levels in a condominium and certain townhomes, depending on the townhome's structure. The ERV system includes a controller that allows homeowners to adjust air quality settings to their preference.
