Yesterday we were talking to a guy who builds ponds and he said that a
vinyl liner will crack in several years and a rubber liner is the way to
go. We were talking to him about how to redo our pond. Is vinyl, which
we have not going to hold up for many years?

Vinyl will last 4/5 years if your lucky. Depends very much on how much
exposed material is in the sun. Butyl is the way to go, usually guranteed
for at least 20 years.

Is Buytl a time of rubber? I've not heard of it before.

Vinyl tends to crack over time. Where EPDM (rubber) has more flex. Usually
they give the life span guarantee of EPDM as 20 years, but if not moved and
always covered with water I bet it last a lot longer.

Anyone have an EPDM pond going longer than 20 years? If so, how long?

"Polyisobutylene" is synthetic rubber.

Does anybody have a good (read: cheap) source for LARGE 30'x60' EPDM. I
have heard the cheaper roofing EPDM is the same as the pond EPDM, but I
have also heard that it isn't. Anybody know the TRUTH?

Firestone makes most, if not all EPDM. Some roofing films have a fire
retardant,
but couldn't not find anything else. MSDS does not list a fungicide
content.
I hear it's all the same, save the FR. But....
Contact Firestone and ask.

When a Georgia contractor says rubber liner, he probably means EPDM,
which some still call rubber, hard rubber or roofing sheet rubber.
Butyl isn't readily available here in sheets, although you may find
some in tapes and sealers for repairs. In fact you will be lucky if
you can find a roofing supply house that still handles sheet EPDM.
I'm in Warner Robins and my first EPDM liner, (An EPDM roofing sheet.)
came from Warner Robins Supply, a local building supply and my last
one from he
http://www.justliners.com/epdm.htm

No, the liner didn't go bad, the lawn timbers rotted. I changed the
pond from a wooden frame above ground to a retaining wall stone frame
above ground.

Yes. It's extremely heavy, and really not the choice of _anybody_ who's
built a large pond before. EPDM (ethyl poly blah blah blah :-) ) is much
lighter, and often has the same guarantee. There are even lighter woven
HDPE (high density polyethylene) plastics - they're certainly the choice
for _very_ large ponds, because they're much lighter and cheaper than EPDM,
but they can sometimes be awkward, as they're stiffer than EPDM.

I haven't purchased EPDM since 2001. Has this gone up in price since I
assume it is a petroleum product? What is the latest on prices? ~ jan

Heavy?? I don't know what you're thinking of Derek, but my liner is only
0.75mm thick.......no weight at all.

Millimeters? Not "mils"? Liners in N. America are generally measured in
mils, and a 75 mil liner is thick. If it's really .75 mm, that's 30 mils,
and I'd say too thin for an EPDM or vinyl liner, but not HDPE and _perhaps_
not Butyl. Either way, butyl is a lot heavier than any of the alternatives
at the same thickness. If it isn't heavier, it isn't butyl.

Thanks for explaining that.
