Radon Mitigation Systems and How they work Integrity Inspections provides top notch services to remove radon/reduce radon. To get rid of radon is called radon mitigation or radon remediation. By far the most common radon mitigation technique is called sub-slab depressurization. The process involves suctioning the soil and radon gas from under the floor of the lowest level of a building. A fan sits outside the living area and is connected to a hole in the floor by PVC piping. The fan discharges radon gas above the roof edge. Sizable openings in the floor, such as cracks and sump pits, are sealed to ensure adequate suction. Radon mitigation systems are permanent to the building and runs 24/7. Typically, the goal is to reduce radon levels to below 4.0 Picocuries per liter of air. Active Radon Mitigation Systems
Active soil depressurization systems use a fan to suction radon gasses from under the home. It is far more effective than a passive system and is the only type of system recommended for existing (non-new construction) homes. An active radon mitigation system, with an electric vent fan and monitoring system, has a vent pipe that stretches from the soil under the lowest layer of the home to up above the roof outside the home. It is a permanent system with the fan running 24/7, and it needs little maintenance. The fans draw about 75 watts and tend to last seven to ten years.
Passive Radon Mitigation Systems
Passive radon systems are like active systems but lack a fan. This type of radon mitigation system uses the natural pressure differential to create an airflow and move the radon out. A passive system is helpful in homes with low levels of radon, but can’t deal with higher levels of the gas, which is why this is the best radon mitigation system choice for new buildings that can’t be tested for radon yet. Research has indicated that in homes with high radon, more than 70% of the time, a passive system will not get radon levels to acceptable levels. Passive to active conversions are possible—a process which is called activating. Activation involves installing a fan and routing electricity. It may also involve putting in a monitoring system as well, depending on requirements. You probably won’t really have to make the choice between a passive versus an active radon mitigation system. If you have high radon levels, a passive system is usually not enough to clear the radon out of your home. Depending on where you live, passive radon mitigation in an existing structure may not even be permitted.
