Yes Mike sometimes I think I'm losing it lol
I dug the pond 3 years ago and it's been leaking ever since
It's about 3/4 acre I've done just about everything I can think of
From adding bentonite to adding polymer to re-coring the dam to compacting the bottom

Lastly I've been coring behind the dam into a layer of gravel where water is flowing
I've sealing it with clay until I hit a rock shelf ....that's when I installed the 12" pipe
Now I want to bust through the rock shelf ( or large Boulder not sure) and continue sealing it

Have any ideas ?
