Radon Mitigation Process

Radon Mitigation is the method for the removal of radon gas from the soil before it decays in to the air particles. Different Methods are used for this purpose but one of them beats the other in every way possible i.e. it is cost effective as well as considered efficient than others. That method is known as active soil depressurization. In this method a slab is used to seal the cellar floor and then negative pressure is generated with the help of a special radon mitigation fans. These fans then draw the Radon from the soil and release it above the floor before it enters the structure. Radon Mitigation is done because Radon sticks with the air particles and when inhaled they goes in the lungs and causes lung cancer. So, In Active Soil Depressurization Radon Mitigation Systems we remove radon gas in vast amount before it enters in the building and causes the inside air to get polluted by sticking with the air particles.

Types of Active Soil Depressurization System

  • A sub-slab depressurization system is very common way of removing radon gas from homes and building and this is mostly preferred as well. In this method a radon mitigation technician digs a hole underneath the sealed floor and creates a what is called a pit or a collection point and above this a radon mitigation fan is installed which creates a negative pressure (vacuum) underneath to remove radon gas. In Older Homes this technique is preferred because they don’t have a sump pump or any such things like that of radon mitigation fans installed for removing radon gas. In modern homes when they are built then sump pumps are installed during the construction so as to remove radon gas from underneath if it is present. Radon mitigation Fans create a vacuum and sucks the radon gas and moisture from the soil as it is continuously running so it keep on sucking moisture and making soil dry which further creates cracks and cervices in soil bed and this will cause the radon gas to release from the cracks and get collected at the collection points. This is then removed by Radon Mitigation Fan System. Basically, a sub-slab depressurization system is known for its moisture removal rather than its radon gas removal.
  • Drain-Tile Depressurization System is another method of radon mitigation system. This is much effective system as compared to that of sub-slab depressurization because it is laid under the whole basement floor in the form of a drain pipe and at the exit(outlet) radon mitigation fan is installed to remove the soil gas. This is effective in a sense that as we know that radon mitigation fan removes radon gas from a place of low resistance so drain-slab will gather the radon gas from different places and collect it to the collection pit so because of this our radon mitigation fan doesn’t have to work so hard as that in sub-slab system. So, this method is rather considered effective as compared to sub-slab system.
