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.

GBThe water-powered backup sump pump… The water-powered backup sump pump seems to be working fine. Your delivery was on time and the kit was not lacking. I asked a question online yesterday and had the answer in a short while.

GB2 attempts, but basement is dry! My crack was difficult as it was the entire wall and it was behind the septic pipe. I was barely able to get it to work behind the pipe. The crack sealer did work, however, I did have to address one part of it 2 times. Preparing the area to accept foam again was not fun. I drilled behind the port this time and slowly injected foam untill the hydraulic pressure of the foam started to break the port off. I would have given this product 5 stars had it worked the first time. I am glad I bought the PRO kit as I used about 2.5 tubes of foam on the repair. I am still happy, it did work!!! We had over 1.5 inches one storm in an already wet week and nothing came in! Basement is dry!!!
