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

I think the jury is still out on the polymer. I don't know of any ponds that have used it and have reported back 2+ years later for long term viability.

BUT, I bet I could guarantee that if you don't apply it like the mfg says it won't work either, just like the bentonite.

Was the pond bottom compacted with anything besides tracks on a dozer or excavator during construction?

If not, in all honesty, you might be better off draining it and properly compacting it. Less $$ down the drain and you'd get on track faster. No sense stocking fish until you know that it's sealed, or if you do, do so with the expectation of loosing all the fish to renovate the pond bottom.
