Our office basement had a seepage/leakage problem for many, many years. The basement walls are constructed with masonary bricks. We tried many other techniques through the years but the issue kept reappearing. We finally tried Seal-it product along with a caulking (for the cracks)and it worked. It has been 2 years now and we do not have anymore leaks or seepage through the bricks anymore. I highly recommend this product and thanks again, Reid, for all your help and advice.
