Planning For Radon Mitigation in your New Home

If your planned home is in an area of higher risk, you should plan early on to install a Radon Mitigation System. In many areas now, a test is required with each real-estate transaction regarding residential properties and this will probably expand to include most of the higher risk areas. In any event, your health is well worth the small investment to install such a system.

  1. how to install a radon Mitigation system in a new home

  2. to suck air from under a slab, the slab must be airtight In the United States, the Surgeon General has warned radon is the second leading cause of lung cancer. Radon can be found all across the US, and can get into any type of building. As awareness of this hazard continues to spread, more and more homes, offices and schools are installing radon mitigation systems. As a member of National Radon Defense, we will take you through one of our standard installations.

  3. Test the sub-slab communication Determining the air flow beneath the slab ensures the system will be able to vacuum the radon particles and vent them out properly. If difficult or problem soils exist under the home, more than one extraction point may be needed.

  4. Seal cracks in the foundation walls and floor The overall goal of the system is to suck up most the air from under the slab that is rising through the soil. Sealing the cracks allows better suction, and increases the amount of soil gas captured by the mitigation system.

  5. Install a vertical PVC pipe, running from beneath the slab and extending through an exit point above the roof line Once the PVC pipe is installed, test the sub-slab communication again to check the system. It is recommended to remove ten gallons of soil beneath the pipe to create more surface area of soil to suck from. Here, we tested the pipe using a shopvac and noticed the pressure readings in the air flow were much different after sealing the cracks around the foundation.

  6. Install a manometer The manometer is mounted on the pipe and has a small tube which is inserted into the pipe. Homeowners can check the manometer to make sure the radon mitigation system is operating correctly. If the fluid inside the manometer is above zero on the side which has the small tube extending out into the pipe, the air is being vacuumed upward and the system is working correctly.

  7. Cut the pipe in the attic and install the fan The fan keeps a continuous vacuum affect in place, sucking up the air from beneath the slab in the basement and venting it out above the home. There are different grades of fans available, homes with compact soils may require a more powerful fan system than a sandy soil home.

  8. Check the system Once the fan is installed, the manometer should have a reading greater than zero. If the reading is still zero, the system has not created a negative air pressure under the slab, and radon particles could still be entering the home.
