Thanks for the reply. I just googled Soil Floc and it looks like a good product, though pricey for a 2 acre pond (~$20K).
Talk to teehjaeh57 here on the forum. He helps people all the time that have leaky ponds by using a polymer based sealing product. Send him a PM and he will respond. I will be meeting him tomorrow early afternoon and I'll mention this thread to him.
