Over 120 condominiums remediated in the Charlotte area

Charlotte Radon, Inc. installs both residential and commercial Radon Remediation Systems.  If a test in your home or building reveals radon levels at or above the USEPA corrective action level of 4.0 pCi/L, remediation is recommended.  Below you will find a description of the remediation methods that we most commonly use.

Active Soil Depressurization

The primary method of reducing radon or Volatile Organic Compounds (VOC's) is active soil depressurization.  A fan and piping system is used to draw enough air from the soil beneath a home or building and exhaust it safely above the roof. This causes the air pressure in the soil to be negative in comparison to the inside of the structure. This negative pressure prevents soil gas from entering into the home or building.  Active soil depressurization systems can be used to reduce radon in buildings built on slabs, crawl spaces or basements.  To see drawings click on this link Remediation Drawings   

Ventilation and Air Exchange are common methods of remediation typically used on homes, condominiums, and offices that have high radon levels as a result of emanation from building materials.  Energy Recovery Ventilators (ERV) are an effective ventilation system used on individual condominium units, homes, and offices.  Large HVAC conditioned ventilation systems are used when remediating an entire commercial building.  All ventilation systems must operate continuously.  Click on the PDF below to view an Indoor Air Quality Brochure as well as the the Owner's Manuals and Installation Methods for the ERV's that we most commonly install.
