Ordered late afternoon Monday and received it early afternoon Wednesday. Product was all there all in perfect shape. If it works as well as the ordering and shipping process it will be a winner.
I left an earlier review when I was frustrated and couldn’t amend it so here’s another…. Product performs wonderfully!! I needed some guidance after the initial application. A rep reached out an... Voir plus
À propos de l'entreprise
Écrit par l'entreprise
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 mission is to supply cutting-edge, professional-grade, and environment-friendly products, superior to those sold in stores. 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. It can be just a matter of time before your basement or outdoor concrete starts giving you problems. Act now and give us a call. We are here to help!

Easy to order
Excellent product
ClayX worked like a charm. Needed a lot of elbow work, but most came off, some areas, all of it came off. I will be purchasing more to finish the small areas left.

Great products!
I have used RandonSeal products on several jobs. They are easy to use and get the job done correctly, the first time! I won’t use anything else!

Arrived Fast
Coverage was as described, but I feel I needed several coats...my porch so porous that it drank it right up.
End result was just ok but only because I think I picked wrong color and need more coats

Foundation Crack Repair and Concrete Crack Repair kits work very well. Web site video showing how to use Foundation Crack Repair is excellent. Ordering and Checkout is straight forward.
I had put off even starting my project
I had put off even starting my project, doubting I could do it well. I watched a really good you tube video (like around 8 times)about Radon Seal and how to do it from beginning to end. I finally ordered it, it came very quickly. And started it the next day. Finished it Saturday. Looks great!

Super efficient process with updates along the way
The process was easy and smooth from order to getting tracking information. I ordered Sept 6th and my package started moving 9/9. I received an email update for every step. Very impressed. Also the tracking says to expect the product by 9/11. So 5 days in total from start to finish. Thank you!
Top Notch

Absolutely love the products
Absolutely love the products. Wish the shipping was a little faster, but I guess that’s on UPS.
Great customer service.

Customer service was very helpful and courteous. Product arrived as promised.
I gave a 4 because of the ease I
I gave a 4 because of the ease I. Getting g started right away. I diagram of how to apply the epoxy to the knobs would have made my life easier. I also ran into an issue with the epoxy at the top and bottom of the wall. There should have been literature for both of these issues. There must be a complete seal in both locations in order for the system to work (continuous flow). You must assume that the people who are using this have zero knowledge. I would still use your product in the future. I just want it to work for all learners.
