Joining liners in an existing pond.

[VABeachPondGuy]

I recently decided to more than double the size of my home pond and quickly discovered that tha application of seam tape is a job for pre construction. Stumped, and not wanting to have to buy a larger liner I came up with the idea of a seaming the pieces together by;

1 folding one piece back and laying the other piece over it with an extra 10" of slack.
2 applying a generous amount of neoprene sealant between the two pieces.
3 Doubling the glued joint over and sandwiching it between two pieces of custom formed PVC trim and bolting the assembly together with stainless steel hardware.

I made the PVC clamp out of 10' sections of 3/4 by 1.5" PVC trim pieces that can be found in the millwork section of any home improvement store. I used a Heat gun, work bench, and C clamps to bend the first piece so that it nearly conforms to the cross section of the pond where the seam is and then I formed the second piece to sit snugly on the first. The next step was to space the two pieces apart to allow for the liner and then I pre-drilled the bolt holes. Assembly was a bit trying as I'm sure you all know how hard it is to puncture four layers of liner when you actually intend to.

I'll send pictures soon as I did it in two locations, one where the new liner joined the old and one where I cut to wrap around an existing tree and form an island.

Trying to picture it in my head but having a hard time can't wait to see the pics. In my next pond it will be bigger and will have an island with a tree in the middle looking forward to seeing pics.

Here we go. I'm terrible about taking progress photos. I'll upload some pics of the island when I get arount to trimming the liner.

Thanks that makes it understandable.........

It's a little cumbersome and takes more rock to cover but both of the splices are holding nicely.
