I've seen above-ground indoor pond/waterfall constructions made
entirely
with natural stones (dressed stones for the pond perimeter and rough
stones for the waterfall). The stones were held together by something
the colour of cement (sand mix perhaps), but the pond interior was
coated
in a thick black sealer (some type of tar). Ponds are in the 800 to
1200g range.
Can someone identify or direct me to a source of this sealer.
Is there any additives used with a sand mix to make it more fish-safe
or
less porous? I'm already familiar with the leeching requirements with
the fresh limestone in concrete products.

At a water garden where I hang out a bit the owner uses something
called thorough-seal to finish the concrete ponds he builds, then uses
them within a few days. I can probably get some more info if you want
to follow up. It ends with a cement-like (gray) coating, although I
guess you could mix in cement coloring to make it black.

I think I've read references to that stuff, so I should be able to track
it down on-line. Thanks.
