Bee, my dam seeps, and leaks, the seeps stopped but the one area that has a larger leak didn't stop, that's why I think it can help only on seepage. Maybe the new product or adding certain organic material with it will yield better results. I have gravity flow pipes supplying 95GPM, but they freeze up when it gets below zero, so this year I put a submersible pump below the dam to return leaking water to the pond. Since the hose is only 40ft. and heavily insulated I'm hoping this keeps the pond level ok for the winter.
