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

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

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.
