I am having to install a liner in a pond/water feature that is to have a reinforced earth wall around the perimeter. Can someone tell me how to handle the liner edges, providing a leak-proof seal at the wall? The pond measures about one acre in size.

For bentonite based liners (IMHO, the best all around type) look thru this document, especially page 13.

The best and most reliable way is to make the connection above the water level, using a batten strip if you have a rigid perimeter wall. The following site shows a typical batten detail: 字串6

We'll use an anchor trench around the edge of the pond to secure a pvc liner.
Make sure to take into account if the liner is UV resistant. If not, you'll need to design the pond in such a way that you can cover the liner.

so much out there to use. we've gone with a 45 mil EPDM and trench it in like atook says for some of our small fire ponds. We would use a HDPE boot with stainless steel straps for penetrations (dry hydrants). We haven't partially lined any ponds as i assume you're thinking about so i wouldn't know about anything to look out for in pond bottom trench anchoring, but i'd bet there is a red flag to catch down there. we cover the liner w/ soil for protection and I've heard that it's hard to walk or stand on a 3:1 sloped wet/underwater liner. 字串6

I've used Bentafix... you might do a search. Also to replace waterbars...
