Goodmorning, hopefully I can explain this, we have two ponds side by
side. I want to enlarge one of them and join them. Since the old
liners are pretty dirty I thought I would replace one liner to the
pond I want to enlarge and join the other pond by laying that same
liner on top of the old one. Do you think this would work? Can this
cause a problem with a liner on top of a old liner later on? The
reason I would not prefer to pull it up is the second pond is actually
attached to a third small pond with a barrier between. The smaller
pond was built to be used as a holding pond for new fish. Thanks.
