We waited 1.5 years to write about the effectiveness of Mr. Sponge's technique and ultimate fix for our 6 wall fractures and complete rod hole replacement. My husband took months to thoroughly investigate all types of repair techniques. We had companys come out to the house, watched videos, went to home shows and got a range of prices from $3500 to $22,000! We chose Mr. Sponge and after 1.5 years of examining the effectiveness of the product and technique we are more than EXTREEMLY SATISFIED that we did! We had a very bad corner crack where water leaked in a steady small stream during very wet weather and were very concerned whether the technique world work on, or not. Since the job was completed we have had the dryest basement in all the the 11 years we have lived in the house. We waited to write this review so we could go through all four seasons of wet weather they produced. We could have spent $22,000 for a fix but didn't have to with Mr. Sponge! HIGHLY RECOMMENDED!
