Andrew,

The life of the material is based on installation. When I was looking at
Permalon for my 16,000 gallon raceways with a concrete slab bottom and
concrete block sides 1 foot above the ground they would guarantee it for 20
years, but if I put the ponds in ground with liner support and dug the top
part of the liner into the top of the pond with a small bream burying the
top of the liner it would have a life time guarantee.

That's where I got the one year warranty idea.
