I'm not sure on trucking bentonite in in large amounts. I had red clay trucked in for my repair. Turned out i had too much sand in my clay core. If you drain pond and work bentonite in you might have better luck. I just sprinkled it on top and let it sink to bottom where i thought leak was. Turned out the leak was 10 or 20 feet from where water was exiting back of damn. It had made a fisher through middle of core. Any experts have some advice?
