For me, in a word it is freezing & weight, my pond is about 6,000 gallons, I
was just not up to mixing, reinforcing & all the other heavy work involved
just to watch it crack and leak with the first hard freeze (Zone 5), to that
end the cost is not important, cheaper or more expensive concrete was not
worth the extra work & time that would be needed each spring to find and
(try) to fix the leaks.

I recently returned from Thailand, and watched a chap build a koi
pond, from scratch, out of concrete, concrete blocks, and mortar. One
person, it took him less than three days to complete. Admittedly it
was pretty rudimentary -- a nearly rectangular pond about 12x20x3 ft
deep. I don't want to get into the debate about whether or not this
is an appropriate koi pond; I can only say that he has two other
smaller ones filled with koi that he has successfully run for over a
decade.

The question I would like to ask is why I see so little discussion
about concrete ponds in the NG, and so much discussion about lined
ponds,,,(and the associated problems with liners, etc.) This is a
serious question, not a troll, from a newcomer to the subject.

I have seen this same kind of pond construction throughout several
countries in that part of the world, so I have to conclude that it
must work. I just don't understand why we don't like it very much in
our part of the world??? Can someone please enlighten me?

TIA, David
