I have a lined pond where the leak is at the bottom rocks also on the bottom. The pond has no water, will this work?

Sodium bentonite is meant to be mixed with the dry soil in the bottom and sides of the pond and compacted. We do not recommend using this on ponds with liners.

I have a small man made concrete creek...flex seal and pool paint has not worked to deal it...will this work?

We wouldn't recommend sodium bentonite for this application. It is best used when you can mix it with soil and compact it.

Can I use this product to seal the bottom of my concrete pond?

We would not recommend using this product for sealing concrete. Sodium Bentonite is designed for sealing earth bottom ponds. We recommend using a epoxy sealant like Pond Shield for a concrete pond.
