I'm looking for a strong water proof adhesive to glue a pond liner. I have a small pre molded pond on top of a small hill. I trimmed a a section of the top off so the water would overun there, flowing down into a larger pond. i have the liner betwwen them with rocks and it flows nice, but whatever glue i use to attatch the the liner to the trimmed lip, water still seeps through and loosens the liner. any ideas? I know this belongs in the pond forum, but that's a lonely forum. Maybe I'll get some replies before you boot me over there. Great pics in that forum by the way, gives me lots of ideas.
