ponds and sidewalks

Question:
How can pond liner be attached to a concrete sidewalk and house foundation?
I have a nice curved sidewalk on one side and the house on the other. I would like to attach the pond liner in some way so it looks like the side of the pond is the sidewalk. Any tips would be appreciated.


Answer:
Dig slightly under the sidewalk and use bricks or rocks to hold the liner in place. The biggest problem with this approach is that the pond is below grade and subject to run off daily from the sidewalk and surrounds.
There is a liquid epoxy spray/paint on liner that works well, but it's very expensive. Check that out.
Another way would be to stack rocks or bricks inside the liner from the bottom to the top of the liner. You would still have your runoff problems tho.
