PROVIDING RADON MITIGATION SYSTEMS FOR THE BUILDING COMMUNITY SINCE 1985


Radon Systems provides passive (no fan) and active (with fan) soil depressurization systems for new construction. Our passive radon mitigation system meets the requirement of the IRC code (Appendix F) and ASTM E 1465-06 for new construction residential buildings located in jurisdictions where radon-resistant new construction is required. According to the EPA zone map, central Ohio is located in Zone 1, which is among the highest in the country. 

Radon-resistant construction features can be installed by Radon Systems when the house is built. If passive techniques are used and the post construction radon measurements indicate that radon levels are elevated, the passive techniques installed by Radon Systems will make it easy and economical to reduce elevated radon levels. Simply adding a fan and a performance indicator should complete the active system, and the post mitigation radon test will confirm the radon reductions. 

Radon Systems has been installing passive systems in Dublin, Ohio since 1996. Recently, Hilliard and Canal Winchester and all of Union County have required homes in their cities to be built radon resistant. All areas of central Ohio have elevated radon levels, so why not build safety and piece of mind into your home. Reduce the risk of lung cancer and demand from your builder and/or local building department that your new home be built with proven new construction radon-resistant methods.


If you are planning or in the process of building a new home, talk to your builder about adding a radon system into your new home.  Several communities in Central Ohio have decided to adopt Appendix F of the IRC code which requires inclusion of at least a passive (no fan) radon system.  Make certain that the passive system is installed by a State Licensed and trained Radon Professional.  Why?  If the system is not installed properly, IT WILL NOT WORK.   A passive radon system installed by a builder or plumber will not be guaranteed because: 
1. Suction point is located on top of the footer: System cannot move air and U-tube monometer reads high pressure because no air is moved from under the basement slab. The radon fan can overheat and operates at the maximum vacuum pressure with no pressure field extension under slab.
2. Radon vent pipe too close to outside wall near the soffit of the house and there is not enough room to install a radon fan in the attic.
3. No vermin guard was installed on the end of the radon vent pipe.
4. Floor cracks, cold joints, expansion joints and mechanical pnnetrations through the slabs are not sealed.  If they are sealed, the wrong types of sealant was used.
5. No electric service was installed in the attic for the radon fan.
6. interior/exterior drain tile is connected and discharging to daylight.  This provides too much air to be removed by the radon system and low or no pressure is indicated on the U-tube monometer.  No pressure field extension under the basement slab.
7. Not all foundations are treated.
8. The crawl membrane is too thin and not properly sealed to the exterior perimeter walls.
9. Radon system is not properly labeled on each floor  and in the attic as required so identifying the vent pipe is difficult.
