Hi Brad
Good to hear from you, been a long time. Per the summary I provide, the linear polymer [A] is designed to work as a flocculant, bind with suspended clay particles, and sink. The crosslink polymer [B] is designed to be carried by the current of the leak into the fissure where it expands and slows, and hopefully seals that leak. Two different polymers, two different functions.
Bentonite serves no purpose for sealing a hydrated pond - it can be used to help sink any polymer that is floating, however - per our original discussion. Feel free to reach out anytime and I'm happy to review and help coordinate your application strategy. Want to make sure we get it right.
I don't see how part B can find it's way to a leak source several feet under water unless it's carried there. Don't see enough negative pressure generated unless you are trying to clog a hole. Plus if part A blankets the bottom then how will part B make it to the leak? That's why I feel part B needs to bind to part A so it can be carried to the leak. Without clay suspended in the water, I'd think the polymers would float around in the water and never sink.
My pond seeps through a rock shelf that I have added 1000 lbs of bentonite and clay over then ran my disc over it. Then packed the layers with my tractor tires. Made 3 layers of bentonite and clay over my leak. It may be sealed now for all I know.
