I lurked and posted here for sometime getting my pond in shape (thanks!)
and
am about to (sigh) enlarge my pond a bit in order to get the H2O
circulating
better (guess I should have lurked a little more before starting).

I'll be using the liner prep, single sided and double sided tape, plus the
silicone caulk that seems to be the way to go. My only hesitation is that
I
don't plan to pull the liner all the way out, thus it won't be flat when I
do the seaming.

Any final advice?

if the tape says you need 24 hours for a seal, give it 24 hours! I didn't
when I joined my stream liner, and I have a leak. When you try to fix the
leak, triple expanding foam is a bad idea. Overtime is absorbs water,
becomes saturated, and then leaches water even faster.

If/When I join another liner, I will take the time to dry it, clean it well,
join it and leave it for at least 48 hours with big heavy rocks on top to
make sure the seal is perfect.

On a side note, we are still in a holding pattern to fix our leak. We had
more frog spawn in the VF, so I can't shut the stream down without harming
them. So I can't repair the leak, not cement over the patch as I plan to do.
