Floor Sealing for Radon Air Mitigation System

Radon is a gas that is constantly being creased from the decay of naturally occurring uranium and radium in the soil. Radon that is created in the soil can find its way to the surface and either disperse into the atmosphere or find its way into your home. Radon use the pathways between individual particles of dirt or it can use cracks and crevices in the soil and foundation of your home. Piping trenches and drainage systems that were installed during your home’s  construction can also be a potential pathway for the entry of radon into your home.

To make matters worse, your home creates a vacuum on the soil beneath it and virtually sucks the radon and other gases out from the soil and into your home. By installing a radon air mitigation system, the radon coming into the basement will be blown into the atmosphere using a fan and piping system. In order for these systems to work, all major cracks in the basement floor should be sealed. If the basement is completely unfinished the floor will need to be sealed with plastic sheets as shown below.
