Pond Boss Forums POND CONSTRUCTION Soil questions Bentonite first...Now a Sealing Polymer...?

I have used a linear polymer on a seeping 1/3 ac pond of mine this Spring - but I know nothing about your specific product. I have spent $3500 total on two occasions draining and trying to reseal the clay to cure with weighted backhoe with no success. I applied $400 of polymer, it apparently found the leak, and has sealed it for 4 weeks. I know...I'm waiting for failure, too.

I have not reported anything yet because I'm still leery of the "silver bullet" product. I figured if this worked, Mike Otto would have learned of it long ago, and in turn we'd have read something from him over the years. This product has been used for the last decade but only in commercial applications - not in a pond/lake setting - so that might account for the lack of research/reports. I wanted to try this so I could possibly introduce it to guys like me who have expensive seepage issues. If this cures my leak, I'll save at least $1000 in electric annually having to supplement leak with my well. Over the course of my life it could end up being a $40,000+ return on my $400 investment. I hate to be skeptical, but it sounds too good to be true.

I am planning on posting a video of my experience and sharing with the forum, but first need to educate myself to a greater degree so I can address questions intelligently and provide the most accurate information possible. I also need to clear it with Bob and Mike before I start flinging product names around and ensure it's ok.

Frankly, I never mentioned anything prior to my experiment because I was 99% certain it wouldn't work due to the ease of application and affordable price. Just didn't add up. Yet, to date I've been happily surprised and cautiously optimistic. I read a case study where this specific product sealed a mining pit constructed mainly of gravel. That really caught my attention - so I decided to try.
