Radon enters homes quietly through the soil beneath their foundations. Pressure differences between your home and the surrounding ground can pull radon through cracks, gaps, sump pits and other foundation openings. SafeBasements installs active sub-slab depressurization (SSD) systems that help redirect radon before it reaches your living space.
With more than three decades of regional experience, our local team designs systems for homes across Minnesota, North Dakota, South Dakota and western Wisconsin, including properties affected by local soil conditions and harsh winters.
Why Your Home May Need a Sub-Slab Depressurization System
Local geology influences how much radon may be present beneath your property and how easily it moves through soil. Parts of Minnesota, North Dakota and South Dakota sit atop geological formations that can produce radon as uranium naturally decays. Because the gas is invisible and odorless, testing provides the only way to measure indoor concentrations. The EPA recommends mitigation when levels are at or above 4.0 picocuries per liter (pCi/L).
Many homes throughout our service area test above this threshold. Foundation openings, including cracks, utility penetrations and sump pits, create pathways for radon entry. Long-term exposure to elevated radon can increase health risks.
Our Approach to Active Soil Gas Management
Sub-slab radon mitigation systems are effective for homes with basement slabs, slab-on-grade construction and partially below-grade foundations. After you’ve had radon testing done, our team comes in to evaluate your home’s foundation and construction beneath the slab. We determine the right extraction point placement for reliable coverage and install an active sub-slab depressurization system.
Here is how the system works:
- Negative pressure: Radon sub-slab depressurization uses a fan and pipe network to create a negative pressure field beneath your concrete slab.
- Radon redirection: The system helps capture radon beneath your home and directs it through piping that extends above your roofline.
- Continuous airflow: Constant airflow helps reverse the pressure differences that can pull radon into your living areas.
Why Local Homeowners Choose SafeBasements
Minnesota’s freeze-thaw cycles, expansive clay soils and wide temperature swings require systems built for local conditions. SafeBasements has worked across the region for more than three decades. Our installations may include:
- Cold-weather components: We use fans rated for outdoor installation in Minnesota winters and selected to help withstand condensation and freezing concerns.
- Foundation-specific placement: We position extraction points based on your home’s construction, whether it has a poured foundation, block walls or a combination of both.
- Lifetime transferable warranty: Our warranty helps protect your investment and can transfer to future owners if you sell your home.
- Post-installation verification kit: We provide a radon test kit so you can check whether your system is reducing radon levels below the EPA action level.
We manufacture many of our own basement waterproofing components and foundation repair products, giving us direct control over quality.
Frequently Asked Questions
Most residential installations finish within one day. Your timeline depends on your foundation layout and pipe routing needs. Our technicians work efficiently to minimize disruption and explain each step during consultation.
Yes. Post-installation testing helps confirm whether the system reduced radon levels below the EPA action level. While we do not perform radon testing ourselves, we provide a post-installation test kit so you can verify your system’s performance.
Fan lifespan varies by system, use and conditions. Most systems require minimal maintenance. Check the pressure monitor monthly to verify the fan operates correctly. Schedule service if the monitor indicates a problem or testing shows elevated levels.
