It happens to thousands of homeowners each year – the sale of their home falls through because of high radon in their basement. They have to hustle to get a radon mitigation system installed and hope that the buyer will not walk away. But for many years after, they may wonder about the long-term effects of the radioactive gas on their children. Since radon gas seeps into basements from the ground, the US Environment Protection Agency had tested the obvious solutions back in the 1980's – caulking all cracks and sealing the concrete with various coatings but the improvements were not significant or lasting. Thus, the fan-based system which draws soil gases from underneath basement slabs became the standard. There had to be a better way! Novion Inc. was founded in 1987 to pursue innovative high-tech solutions. Penetrating concrete sealers, already well-proven for waterproofing concrete on major projects, seal concrete internally and permanently. Perhaps, they could be improved to penetrate deeper and seal even tighter to keep out the single-atom radon gas. After extensive research and testing, the first concrete sealer specifically developed to reduce radon infiltration through concrete was ready for the big debut – RadonSeal® Deep-Penetrating Concrete Sealer. Novion Inc. was incorporated in Connecticut and RadonSeal was made available directly to homeowners and contractors on radonseal.com website. Subsequently, we have continued to add unique innovative products, not available in stores, for basements, indoor or outdoor concrete, bricks, pavers, and masonry. Going beyond radon remediation, we provide durable and cost-effective solutions for waterproofing basements, sealing concrete slabs against vapor, and mold remediation. Our products also protect and beautify indoor or outdoor concrete, pavers, and masonry.

Our customer support offers technical expertise and objective guidance on the best solutions for customers' needs. Whether you are a homeowner, contractor, or building owner, we will provide the top-quality products and service to solve or prevent problems with your basement, parking lot, pool deck, brick or masonry walls.

Instructions were simple and strat forward.
We had record rain fall a few days after using your product and NO leaks or water in the basement. It sealed great!
Happy with prompt delivery
2 day delivery from order placement, exceeded my expectations.
Ordered directly from distributor rather than a third party because the product needs to be fresh and not stored for a prolonged period of time.
Gentleman I spoke with was knowledgeable about product and my price question. Fast friendly service, shipped that same afternoon.
