If you care, you really are not going to see the folds all that much if
you
decide to do the liner. The size pond you are talking about (5' round X
2'
deep - shelf ~ 8" for us fools that use the kings measure) is such that
you
should be able to easily find a preformed one in any place that sells pond
supplies. They work fine but this is small and you should be careful not
to
have too many fish and to keep your eye on water quality.


Had to correct typo and add that I knew a woman that had a pond of this size
and she raised a couple of fantails and some huge comets (8-12") in it.
Her water was always crystal clear and her fish the healthiest and most
friendly I have ever seen. It was really very nice.

Hi folks,

I am planning to build a circular pond and was wondering if anyone can
comment on preformed 'welded' butyl liner? A few companies say they can
do this and it sounds like it might be what I'm looking for. The
dimensions of the pond are radius 1500mm, depth 600 with a 200mm deep
shelf. One part will be slightly overhung by decking.

If I use a flat piece of liner there will be lots of folds so was
wondering if the preformed liners are any good? Are there and potential
problems?

An alternative I have been advised is to build the pond in concrete
with bituminous coating. Someone else then commented that certain fish
might not like the coating? I don't plan on havig Koi. Probably
goldfish, orfe and the odd tench or ghost carp.

Thanks in advance!

Gary.
