Michigan Radon and Crawlspaces

Do you have elevated radon levels in your home? If so, you will have to start looking into having a radon mitigation system. It is important that crawlspaces are taken into consideration when the company is coming up with a design for your radon system. There are a few types of crawlspaces in Michigan and they absolutely need to be included in the radon mitigation design. 

Some crawlspaces have a dirt floor and are not covered with concrete. These crawlspaces are definitely entry points for radon gas to enter your home. In situations with a dirt floor the crawlspace has to be encapsulated. Our team installs a 20 MIL cross-braided barrier over the open dirt floor of the crawlspace. The barrier is then professionally fastened and sealed to the crawlspace walls so they are air tight. In most cases drain tile can be installed under the barrier and connected to the radon system. This will create negative pressure under the encapsulated crawlspace safely venting the radon and other soil gases outside. 

Other crawlspaces have concrete floors. These areas are often elevated above the original slab of the home. A radon reduction system with one extraction point in the basement will not include the crawlspace making the system inefficient. It is important to create another radon extraction point for the crawlspace and connect it to the radon system. This will be sure to create the needed negative pressure under the crawlspace slab efficiently lowering your radon levels. 

Make sure when having a radon system installed that any space that may not be part of the original basement if being impacted. Multiple radon extraction points can be used with one radon reduction fan to cover all areas of your home.
