Is your health being affected by radon gas buildup? Radon is a naturally occurring gas and the second-leading cause of lung cancer. In some parts of the country, the breakdown of certain rocks and minerals ultimately leads to the release of radon, which is odorless, colorless and causes no symptoms in people who are exposed to it. The only way to know whether your home is affected by radon gas buildup is to have it tested. If dangerous levels of radon are detected, then a radon abatement service can take actions to divert radon from your home and dilute it into the atmosphere. Have more questions about the abatement of radon gas? If so, read on to learn more about the top three radon mitigation options.
First, it’s important to note there are numerous radon abatement options, and the type that’s ultimately best for you depends on whether your home has a basement or slab foundation versus a crawlspace with a foundation. Beyond that, other considerations - such as the layout and drainage qualities of your property - will influence the type of mitigation option you receive.
Topping our list of the top radon abatement options is active sub-slab suction, which is for homes with basements and slab-on-grade foundations. This is the most common option for radon abatement, and it’s also usually the most effective option. With this option, at least one pipe is inserted through a hole in the floor slab, and the end of the pipe is pushed into the rock and soil beneath your home. Most houses need just a single pipe, but some need several depending on the severity of the radon problem. Vent fans are connected to these pipes, which carry the gas to the outdoors where it’s disbursed into the air. This option creates a permanent suction that carries radon gas around and outside of your home before it has a chance to enter and do harm.
Next on the list is crawlspace sub-membrane suction, which is for homes with either crawlspace foundations or basements with dirt floors - which are rare, but do exist. With crawlspaces and dirt floor basements, radon can’t just be suctioned around the foundation. This radon abatement option calls for the dirt floor of the crawlspace or basement to be covered with a thick sheet of radon-resistant plastic and for vent pipes to then divert radon gas from beneath the plastic to the outdoors. It’s the same concept as active sub-slab suction, but the radon-resistant plastic is used to create a barrier that stops the widespread venting of gases into the basement or crawlspace.
The third option on our list is crawlspace ventilation, which is also for homes with either crawlspaces or dirt basements. With this option, affected areas are ventilated by the use of openings and fans. Some basements and crawlspaces are actively ventilated (by using fans), while some can be passively ventilated by creating or closing vents. Active ventilation may cost more because of the persistent use of electricity, but it also tends to be more effective. There are numerous options for radon gas mitigation, but these three options are the most common and often the most effective.
