Attaching pond liner to an existing uneven wall.

[ruthimogen]

Hello! I'm increasing the depth of an existing small rectangular pond in my garden. Two sides will be the heights of three railway sleepers. The other two sides are raised beds made of Bulwell stone. The raised beds are higher than the sleeper height will be. I'll lay the pond liner over the sleepers and then put a final sleeper on two sides to cap it. However, I don't know what to do about the two sides that are walled. The liner will not come all the way to the top so I can't cap it, and the stonework is so uneven that I don't think I could add a termination bar. It will be a natural wildlife pond with no fish. Any ideas please?!

Maybe glue the liner. Then,never tried it myself but there is this stuff call rock on a roll that could help hide issues maybe. Not sure what else to do. Some others will have ideas for you.

Here are some images I found of it. It gets better as it ages I believe.

If your adding two landscape ties on top of the existing . that should leave you just one course of stone above the landscape ties. pOP OFF THE LAYER OF STONE PLACE YOUR LINER and mortar the stones back
