Derek....thanks for the info. You are probably right on the name of this
black and white stuff (my original was the black and silver) and if it
wasn't for me and my ideas it would probably still be just fine. i.e.
different falls, adding a bog etc. etc. I found that it folded quite well
though. Just helped my brother put in two ponds and a stream a couple of
weeks ago and he was pleased with the stuff. The company cut and heat
seamed it to the size he needed and the two of use were able to put it in. I
can just imagine the weight of EPDM! I know some folks frown on using
anything other than EPDM or roofing rubber washed off (which is the same
thing). If I get a chance I'll look up the company name and post it, I'm
pretty sure it is Tarp Right, but I'll check.
Thanks again.
Bev

I think it is 1.24 per sq foot. This stuff is the same as the original
pond and has served me very very well. It is easy to work with and folds
really well. It is also good for patching should it require any
(haha...of
course it will!!)

Well, I consider it not adequate for ponding if it requires patching. One
problem with HDPE, is that it doesn't fold very well. But the stuff from
Northern Greenhouse shouldn't ever need patching. If it gets to the point
where it's getting leaks, it's probably beyond patching. One guy claims
to
be able to walk on his greenhouse roof. Last week, something blew through
our greenhouse - took out a window, but no damage to the plastic.

When I started ponding all those years ago this was the only
stuff available around here, cost me 300.+ for that liner!!!

Yeah, I spent hundreds on the liner for my first pond.

For the big pond I would
love to be able to get the EPDM....but it would cost a considerable
amount. Maybe by then the craze will die down and the costs will reflect
it.

No, the costs actually do reflect the "craze". Things were much worse
when
there was no demand for pond liners. Supply & demand. When demand goes
up, so does production, and prices start to come down. For the size of
pond
you have, you probably wouldn't be able to drag the EPDM liner into
place -
even with help. My last pond had a liner about 600sq.ft. and it was
barely
possible for my wife and I to get it in place. HDPE is much lighter and
more puncture resistant.

Someone told
me mine is a PVC liner??? Black one side white the other, a woven
material. Nice to meet you all, I look forward to sharing ideas.

No. The blue pool liner is almost certainly PVC. The woven stuff is HDPE
(High Density PolyEthylene). Black & white may even be the same stuff
that
Northern Greenhouse is selling (they say theirs is black/silver).
