If you are looking into radon mitigation system installation, then you will need to look into a few factors before making a final decision. That is because not all radon reduction procedures are created the same. If your home has a foundation type that falls under either the basement or slab-on-grade category, then you generally have a few different techniques to choose from:
1. Active Sub-Slab Suction
This is the most common type of procedure. It involves inserting one or more suction pipes through the floor slab and into the ground underneath it. The radon gas is then sucked up from underground by a radon vent fan. This not only creates a negative vacuum beneath the slab, but it also releases the radon it into the outdoor air.
2. Passive Sub-Slab Suction
While this is quite similar to the procedure mentioned above, it instead uses natural pressure differentials and air currents in order to suck up radon from underground. Unfortunately, this method is not as effective as active sub-slab suction, according to the Minnesota Department of Health.
3. Block-Wall Suction
Often used in conjunction with sub slab suction, this procedure entails the use of depressurization in order to remove the radon. This works best in homes that have hollow block foundations.
4. Drain Tile Suction Systems
In this method, perforated pipes are used to direct water away from the foundation of the house. It can also be used to pull radon away from the soil done by forming a partial or complete loop around the home. It is found to be quite effective in lowering the levels of radon in many residences.
Whichever method you choose, make sure that you hire a company that’s experienced with radon mitigation system installation. That way, you’ll have the peace of mind you need, knowing that your home’s safety is in good hands.
