How Radon Abatement Works

The greater Portland Oregon metro area has some of the highest radon gas levels in the country. The goal of radon abatement is to trap radon before it enters your home and to give it a path to escape harmlessly into the open air. Here’s a look at how it works.

Find The Source
Radon gas is formed in the earth’s crust. It comes into your home through the easiest path possible. Usually through cracks and openings in the slab, foundation, sump pumps, and crawlspaces. Another way that radon gas enters a home is through older floor drains not equipped with a trap. It can also enter through collection pits for water overflow, that look like floor drains, but they aren’t attached to any type of plumbing. See picture.
Create An Exit
Next, we build a system to draw the radon gas out of the home. Many companies use inexpensive thin wall Schedule 20 PVC pipe. We only use the strongest, most durable Schedule 40 PVC or ABS piping to suck the radon out of your home. Our systems are designed to be so long-lasting that they come with a “Double Lifetime” guarantee that extends for as long as you own the home… and the next owner.
Create An Exit
Radon gas WILL enter your home. A radon abatement system determines where the gas will go. We core a 6″ hole in the slab and then remove up to 15 gallons of dirt from underneath the slab. The amount of material removed might be the single most important step that’s taken. Most mitigators don’t go to this much effort and make up for it with a larger, noisier fan. They then offer an inferior performance guarantee of up to 4.0 pCi/l. By creating a huge”suction pit” under the slab, it gives the radon a place to collect. Our unique abatement designs allow us to offer industry-best performance guarantees down to 0.5 pCi/l.
Create An Exit
A radon abatement design is like building an enormous vacuum. We seal the suction pipe into the suction pit. The pipe is then routed to a high-performance radon fan that’s installed outside. (we use sound dampeners at every connection to the house). Additionally, we seal EVERY crack we have access to. Radon can enter a home through a small crack like a fire hose. If you have a finished basement we’ll use our FLIR E8-ET Thermoscanner to search for cracks under the carpet so we can seal any cracks found there. Carpet won’t stop radon gas. Our FLIR scanner will save you the expense of having to pull back the carpets to find those pesky slab cracks.
Create An Exit
Every company has a choice of fans to use in their installations. We use the best: PERIOD. Our fans are the quietest, most efficient, and longest-lasting fans available. They’re made in America and come with a 10-year warranty. Every other company offers a 5-year warranty on their Chinese fans unless they charge you more. Our high-efficiency radon fans create a vacuum that draws the concentrated radon gas up and safely away from your home 24 hours a day, 7 days a week… for decades.
