Getting to Know Radon and Why It’s a Problem

Before we talk about the solutions, let’s understand the problem. Radon is a gas that comes from the ground and can get into our homes. It’s not something we can see, smell, or taste, but it’s there, and it can be harmful.

How Does Radon Get Inside Our Homes?

Why Should We Be Concerned About Radon?

Radon is harmful because it can cause lung cancer. It’s actually the second leading cause of lung cancer, right after smoking. It’s believed that radon causes thousands of deaths each year.

The Top 4 Residential Radon Mitigation Systems

Now that we know why radon is a problem, let’s talk about the solutions. Here are the top 4 residential mitigation systems that can help keep your home safe from radon. These systems are designed to redirect harmful radon gas away from your home.

Sub-Slab Depressurization Systems (SSD)

The Sub-Slab Depressurization (SSD) system is a popular and reliable way to reduce radon. This type of system is commonly used in homes with a basement or slab-on-grade foundation. It’s designed to address the radon at its entry point – the ground beneath your home.

How Does an SSD System Work?

The SSD system works much like a vacuum cleaner, but instead of dust, it’s sucking up radon gas. Here’s how it works: a hole is drilled into the concrete slab of your home’s foundation. A PVC pipe is then inserted into this hole, extending up through the house and out the roof. At the top of this pipe, a special fan is installed. This fan creates a vacuum effect, sucking up the radon gas from beneath the slab and expelling it safely above the roofline, where it quickly dilutes and becomes harmless.

This process effectively intercepts the radon before it has a chance to enter your home, keeping your indoor air clean and safe.

Installing and Using SSD Systems

When it comes to installing an SSD system, it’s best to leave it to the professionals. This isn’t just a matter of convenience—it’s about safety. Radon mitigation is a specialized field, and a poorly installed system might not only fail to reduce radon levels, it could even make the problem worse.

Professional radon mitigation contractors have the training and experience to install these systems correctly. They’ll also perform a follow-up test to ensure the system is working as it should. Once properly installed and maintained, an SSD system can reduce radon levels in your home by up to 99%, providing peace of mind that your home is safe from the dangers of radon gas.

Drain Tile Depressurization Systems (DTD)

Drain Tile Depressurization Systems, or DTD systems, are specifically designed for homes that already have a drain tile system in place. Drain tile systems are commonly installed in homes to manage water accumulation around the foundation, often working in conjunction with a sump pump to keep basements dry. But did you know they can also be a part of your radon mitigation strategy?

How Does a Drain Tile Depressurization System Work?

A DTD system works by capitalizing on the existing drain tile system. The drain tiles, which are essentially a network of pipes around your home’s foundation, can also serve as a pathway for radon gas to move.

The DTD system uses a fan to create a vacuum in the drain tile system. This vacuum effect sucks up the radon gas that has entered the drain tiles, preventing it from seeping into your home. Instead, the radon gas is safely vented outside, well above the roofline where it can disperse harmlessly into the atmosphere.

It’s important to note that the DTD system doesn’t interfere with the primary function of the drain tiles and your sump pump. They will still work to keep your basement dry by redirecting water away from your home’s foundation.

Installing and Using Drain Tile Depressurization Systems

Installing a DTD system requires professional expertise. It involves connecting a vent pipe to the drain tile system and installing a specialized fan to create the necessary vacuum. The vent pipe is then extended upwards, usually on the exterior of the house, to safely release the radon gas outside.

Once installed, a DTD system can significantly reduce the radon levels in your home, making it a safer place for you and your family. Regular maintenance checks are recommended to ensure the system continues to operate effectively.

Block Wall Depressurization Systems (BWD)

Block Wall Depressurization Systems, or BWD for short, are specifically designed for homes with hollow block foundation walls. These types of foundations are common in many older homes and can pose a unique challenge when it comes to radon mitigation.

How Does a Block Wall Depressurization System Work?

The BWD system operates on a simple yet effective principle. Radon gas, which enters the home through the soil and rock beneath the foundation, can accumulate in the hollow spaces within the block wall foundation. The BWD system works by creating a vacuum within these hollow spaces.

A hole is drilled into the block wall, and a pipe is inserted. This pipe is connected to a fan that creates suction, pulling the radon gas from the hollow spaces in the block wall. The radon gas is then safely vented outside the home, preventing it from entering the living spaces.

Installing and Using Block Wall Depressurization Systems

Installation of a BWD system should be done by professionals due to the complexity of the task. Once installed, the system runs continuously, effectively reducing radon levels in homes with block wall foundations. Regular maintenance checks are recommended.

Sub-Membrane Depressurization Systems (SMD)

Sub-Membrane Depressurization Systems, or SMDs, are a specific type of radon mitigation system designed for homes with crawl spaces. Crawl spaces can be particularly susceptible to radon accumulation due to their close proximity to the ground and often poor ventilation.

How Does a Sub-Membrane Depressurization System Work?

The SMD system works by creating a physical barrier between the crawl space and the rest of the home. A durable, puncture-resistant plastic sheet is carefully placed over the entire floor of the crawl space. This sheet acts as a barrier, preventing radon gas from seeping up into the home.

But the system doesn’t stop there. A specialized fan is connected to a pipe that extends from the plastic-covered crawl space to the outside. This fan creates a vacuum effect, sucking up the radon gas trapped under the plastic sheet and safely venting it to the outdoors. This way, the radon gas is redirected before it has a chance to enter your home.

In addition to the SMD system, crawl space encapsulation is often recommended. Crawl space encapsulation involves sealing off the entire crawl space with a vapor barrier on the floors, walls, and sometimes even the ceiling. This not only helps to prevent radon gas but also moisture, mold, and pests from entering the crawl space and subsequently your home.

Installing and Using Sub-Membrane Depressurization Systems

Professional installation is crucial for an SMD system to ensure its effectiveness. Once set up, it can significantly lower radon levels in homes with crawl spaces. Regular checks are advised to maintain its performance and to ensure the system continues to protect your home from radon exposure effectively.
