my pond used about four different pieces of liner, they added up to about 500-600 square feet,(as you can see I folded a lot up rather than cut it because I may want to make the pond bigger some day) I only used about half of what I had to begin with, and I still have some (sold some) but the whole thing only cost $50! the liner is proper rubber liner but it was recycled roof membrane from a commercial flat roof system (you know the ones with the gravel on them) I got it at my local construction material recycler place, it weighed in around 300 lbs! and it took 5 guys to put it in the van! so if you're looking to build a pond try one of those "renovator resource" or demolition places....
mine was four pieces simply because one piece was the pond and the next was the top river the next was below the falls, etc. I did'nt glue anything but I simply overlapped it in such a way so the water would simply flow over the seam and down the stream. the rubber is the roof covering that they use just below the pebble layer, not all roof systems are done the same way and not all roof membranes are like the pond liner stuff you would maybe want to take a small piece of pond liner to a recycler to see if they have anything like it....(you can use other stuff for a pond liner as well but this stuff is pretty tough. and somewhat easy to come by, especially if you live near a large metropolitan area... actually if you were to go to a local commercial roofer they may have old pieces or maybe the stuff is'nt too much brand new?
