Does the Liner (EPDM, rubber, or Vynil) have to be

Generally, yes. There are tapes and sealants for seams,

What do you do when the pond you wanna build is too
big for any liner that's out there? Can you glue/overlay pieces
together with silicone sealer or something?

If you don't have an alternative...
