If you’ve done a radon test and the results came back showing that the level is higher than 4 PCi/L, then you definitely need to install a radon mitigation system. Usually this system keeps the gas concentration to lower levels that cannot be harmful. In fact, it lowers the levels up to 2 PCi/L. Interestingly, If you later decide to sell the house installed with this system, the price will be definitely tangible.
Basically, it would be best to inquire from an expert opinion before installing any radon mitigation system. However, if you choose not to, then you ought to consider certain criteria. For instance, the type of foundation and the design of the house. Here you’ll find that there are houses that have a simple space under the first floor, some with concrete-poured on the ground level, some that combine these two foundation designs, others with a crawl space and half a slab-on-grade etc.
Whichever the design of your house, there are several procedures that may be required to achieve radon mitigation. Generally, you can opt for prevention by using special devices that may prevent radon from entering the house or you can choose to lower the gas concentration. Installing underground fans, radon contractors, sealing cracks and openings in the walls etc, are some of the measures you can undertake to control radon.
Such things as the soil type beneath the house, foundation design and so on, are some of the special diagnostic tests that should be done before you start on the radon process. Nevertheless, it would be better and wise to talk to the team in charge of the whole procedure and analyze every detail together.
