Pond Boss Forums Thread Like Summary - Fixing a pond leak with bentonite while full

I have a question about sealing my recently constructed pond with bentonite. I don't really want to dewater the pond (its about 30% full). I have the leaking area isolated and was considering purchasing bagged bentonite and then mixing it with water and basically pumping the bentonite slurry into the leaking area of the pond. It seems like using this method I could avoid issues with sprinkling the bentonite and get an even distribution of the product in the leaking pond area. Has anyone ever tried this method?

I have used bentonite in full but leaking ponds to stop leaks. I am not saying another product might not work better but that was not your question. The clay can act to fill the pores in sand and form a seal. That is why it was developed for the oil drilling business. I have used successfully the method you described.
