GBRadonSeal's eflorescence is tops Their eflorescence cleaner has little or no odor. It works effectively at neutralizing calcium bleeding through concrete block. I tried strong vinegar, it was ineffectual. Years ago I tried muriatic acid which worked about the same as RadonSeals product- but the smell was horrible. I ran short on this job, so I ordered another gallon- it works !

GBThe application process has worked well… The application process has worked well up to this point by simply following the printed and on-line tutorial instructions. I'm now waiting for the coming spring rains to tell me if the work done on the first crack was effective. That will be the true test. The only issue I encountered was running out of filler material after filling only 2/3 of an 8' long hairline crack in an 8 1/2" wall and having to order another tube to complete it. There should be a 3 tube kit.

GBProduct performance was very good, instructions lacking Product performance was very good. However, design function of the caulking style tube was not. A normal tube is empty when the charging rod is fully deployed inside the empty tube. Without knowing the charging rod is fully deployed at 3/4 of its normal length caused considerable delay and improper injection of the polyurethane foam into the concrete wall.

GBSeemed to Work Perfectly I was quoted $1800 by two different waterproofing companies to fix a hairline crack in a concrete foundation wall. After a little research and a phone call to RadonSeal's Technical support, I chose RadonSeal Polyurethane foam. The process was just as easy as their YouTube videos indicated. I bought a 10 ft. kit for a 9 ft. crack and it took the entire 2 tubes with the polyurethane oozing out the top of the wall. Although I have not yet had a rain to determine if it was 100% effective, I feel confident that all will be well.
