How to Install a Radon Mitigation System
A radon mitigation system is an important addition to any home or business. Radon is odorless and colorless as well as tasteless. Prolonged exposure to radon can cause cancer and is the second leading cause of lung cancer. Radon is a gas that is radioactive and is created when uranium decays. Uranium can be found in rocks, water and soil all over the world in varying levels.
The human body can tolerate certain amounts of exposure. This is because radon is found everywhere as normal air carries around 0.4 pCi/L of radon. Radon gas inside a building can increase over time to dangerous levels. This can increase if there are smokers present. A radon mitigation system is used to reduce the amount of radon in the air. This is a job best left to a licensed radon mitigation system contractor but the article below will explain how the installation is done.
Step 1 – PVC Vent Pipe Access
A vent pipe is used by the radon mitigation system to transport the gas from the basement to outside of the home of building. A pencil will be used to mark the area in the basement floor where the PVC vent pipe will be installed. In most circumstances this will be near other equipment in the home like the hot water heater. After the location is marked a rotary hammer is used to create several holes to outline the marked area. The demolition hammer is then used to break away the concrete floor. Once the concrete is removed the dirt will have to be removed with the soil-auger bit attached to the drill. The goal is to create a 20-inch diameter hole.
Step 2 – Install the PVC Vent Pipe
Now that the hole has been made the vent pipe can then be installed. The vent is placed in the hole afterward. They will ensure that it s tight and will backfill soil to make sure of this. The PVC pipe is then run through the walls of the structure and into the attic.
Step 3 – Sealing the Hole
A foam rubber backer rod is placed around the base of the PVC vent pipe with it is residing just below the concrete floor’s surface. The area around the pipe is then sealed with hydraulic cement.
Step 4 – Venting Radon
The PVC pipe is attached to a venting fan in the attic using metal brackets. The pipe is then continued from the vent to the roof and is attached to a roof cap.
Step 5 – Radon Mitigation System Installation
With the venting system in place the radon mitigation system is then installed in the basement to cap the PVC vent. The monitor system is then installed. A small hole is then drilled in the floor of the basement and the draw of the fan from the radon mitigation system is checked with a smoke pencil.
