Why Basement Floor Coatings Are a Smart Solution for Radon Mitigation

Homeowners in Washington and Idaho may not always think about radon, but parts of the Inland Northwest have elevated radon levels due to the region’s soil composition. This radioactive gas enters homes through unfinished basement floors, cracks in foundations, and porous concrete, accumulating over time and increasing the risk of lung cancer. Since radon exposure is a serious health concern, radon mitigation is a smart investment in home safety.

How an Epoxy Basement Floor Coating Helps Block Radon

One of the most effective ways to reduce radon intrusion is by installing an epoxy basement floor coating. Here’s how it works:

• Creates a Non-Porous Seal – Bare concrete allows radon to rise through tiny openings. A seamless basement floor coating forms a protective, airtight barrier, reducing radon infiltration.
• Prevents Moisture Damage – Spokane experiences seasonal rain and humidity, which can weaken basement floors and create cracks. Basement floor coatings provide moisture mitigation, preventing further structural issues that could increase radon exposure.
• Long-Lasting Protection – Unlike temporary solutions, a high-quality basement floor coating offers durability and longevity, ensuring your basement remains radon-resistant for years to come.

Strengthening Radon Mitigation with Additional Measures

While basement floor coatings help block radon, additional mitigation strategies provide even greater protection:

• Radon Testing – Conduct regular radon tests to monitor levels and determine if further action is necessary.
• Active Radon Mitigation Systems – If radon levels exceed safety thresholds, installing a sub-slab depressurization system (which uses a vent pipe and fan to direct radon gas outside) is highly effective.
• Sealing Additional Entry Points – Beyond flooring, sealing foundation walls, crawl spaces, and utility penetrations can further minimize radon seepage.
