Active Dampness Control & Radon Reduction for New Construction

Active Dampness Control (ADC) Systems , (aka radon mitigation systems) are designed and engineered to reduce indoor air health risks by preventing radon, water vapor and other soil gases from entering the home.

Active Dampness Control (ADC) System™

An active ADC System quietly and unobtrusively provides better indoor air quality and a healthier living with no homeowner maintenance. Most systems use about the same amount of energy as a low wattage light bulb.

Each home is retested for radon concentration immediately following occupancy. Homeowners are provided with graphical representation of hourly radon concentration test results, performance guaranty and transferable warranty.

An ADC System helps to protect home occupants by improving air quality for a healthier, more comfortable indoor environment:

  • Reducing moisture, allergens, summer time humidity, radon and other harmful soil gases
  • Preventing as much as 1,000 gallons of water vapor from entering the home annually
  • Reducing moisture-related health hazards such as mold and mildew and insect infestation

Eliminate some of the toxins and allergens that can cause:

  • Lung cancer
  • Asthma
  • Severe allergic reactions
  • Headaches
  • Sneezing
  • And a long list of additional mild or serious allergen-induced symptoms

Active Radon Systems / RRNC create a healthier home environment by reducing the likelihood of moisture-related new-home problems such as warping wood, odors and mold or mildew.


What is RRNC?

RRNC (Radon Resistant New Construction) refers to the process of preparing a new home for the installation of a radon system during the early construction phase and is identical to the installation of an Active Dampness Control System, rough-in.


Does RRNC with a Passive System Reduce Radon?

A passive system or RRNC may provide some reduction in radon levels based on the natural convection of heat rising up through the home, (stack effect), but an active system will greatly reduce radon levels in nearly every new home. Both terms give the impression that a home is safe from radon, however a home with RRNC or a passive radon system is not guaranteed to resist radon nor is it guaranteed to be radon free.

These two simple and relatively inexpensive additional steps will make a passive or RRNC system active:

1. Add a radon fan.

2. Test the radon level.

 

Testing

The first step to help ensure the safety of you and your family’s health and safety is to have your home tested for radon. At St. Louis Radon, our professional testers deploy the latest in computerized electronic real-time radon monitoring technology to provide you with a comprehensive report, including a complete visual graph of radon level data points as recorded over a 48-hour sampling period.

Mitigation

If testing indicates levels of radon that require action, our team of engineers and technicians will design and install a custom radon mitigation system to safely and effectively redirect radon and other soil gasses out of your home. We also take additional measures to seal and close other possible breaches in the foundation that could let soil gasses into the through cracks or drain tiles systems.

New Construction

With new home construction projects, it is crucial to determine the level of radon that may be present in the soil before the home is built. It’s also critical to have the new home retested for potential radon concentrations immediately following occupancy. We also highly recommend installing an Active Dampness Control System (ADC) with every new build.
