They sell a two sided liner tape that is good for that---if you can't over
lap the cut--then just add a piece of liner like you would do in a swimming
pool and use the tape to bond it.

I have a small preformed pond that has split. I sealed it with
silicone but the leak is back and the split a little larger. Is there
an easy way to seal the tear?

thanks
