radon MitigationS
Radon Mitigation systems go by several different names like Radon Reduction and Radon Remediation, Their purpose is the same. They reduce radon in your home.
However, there are different methods to mitigate radon. Some homes have passive systems. It's important to know that passive radon systems only work some of the time. They do not reliably reduce radon levels and are susceptible to barometric pressure, wind and etc. In fact, passive systems in the wrong weather patterns can increase radon levels in your home.
At Z Radon Basement and Waterproofing we primarily install ACTIVE RADON MITIGATION SYSTEMS. The most reliable and effective active radon mitigation process is called a SUB SLAB DEPRESSURIZATION SYSTEM or SSD. This is what we recommend, what we primarily do and what we are particularly good at.
​
Sub Slab Depressurization systems involve tapping into the air under your home through a suction point. A fan will work continuously to draw radon out from under your home, before it even enters, and a pipe will disperse it out and away from your home. Basically, we are creating a vacuum under your home, drawing the radon out and blowing it away from your house. ​​

90% of Z Radon Basement Radon Mitigation System are under $1500.00.

Sub Slab Depressurization Systems or SSD’s allow us to collect air and the radon within it from below your basement slab.
​
A hole is drilled through your basement slab and some diagnostics will be run to confirm that this location will allow us to achieve some suction through the soil. If diagnostics prove it to be a good location, this will become a suction point. For homes that have sump pumps or sump pits, often this can be used as a suction point.
​
Then, a pipe is inserted into the suction point and sealed to allow for better suction. Cracks as well as sump pits are sealed for the same purpose. This concept can be compared to drinking from a straw that has small holes in it or one that does not. From the suction point this pipe will lead to an exit point and fan.
​
The fan, which runs continuously to move air, will create an area of low pressure activating the system to pull out the radon gases. With the fan on, our vacuum has been formed. To measure the suction strength of our vacuum/ system a U Tube will be placed on the pipe. The pipe will act as a hose collecting and directing air from the soil below your basement slab. It’s important to note that fans should never be in the interior of your home, with the exception of an unfinished attic or possibly a garage.​​
After exiting your wall, pipes will run up the side of your house and end with specificity to blow the radon out and away from you home. Certified mitigators are knowledgeable about guidelines for appropriate pipe terminations to ensure that radon will not reenter your home. It may be helpful to know that, like all gases, radon likes to move in straight lines and up.
​
SSD’s are the most consistent and reliable form of radon mitigations systems.
​
This same process can be applied to crawlspaces. However, for homes with dirt crawlspaces the crawlspace will need to be encapsulated with a radon graded membrane and sealed.
For such systems the technical term is a Sub Membrane Depressurization System.

WORK​
YES! We do crawlspaces too!
​
Whether you have a dirt or a concrete crawlspace, we can help.​
​
Concrete crawlspaces tend to be easier and lower in cost.
​
Dirt crawlspaces require a little more work.
Before a dirt crawlspace can have a mitigation system installed it will need to be encapsulated.
What this means is that we will line and seal your crawlspace with a radon specific membrane,
CRAWLSPACES
Factors that impact crawlspace encapsulations and mitigations:
​
Size
Accessibility
window? door?
How much clearance do we
have to get in there
How many obstructions and/
or sealing points will we have​
