950 Plywood/Acrylic Build on Wheels!

There are methods to fold liners to achieve the flush look. Basically, all edges should be above water level. Only drains and window cutouts require some form of leak protection (usually mechanical clamping with flanges and/or bolts).
Koi forums and a few above ground pond builds on MFK has good info. Even Neo had a thread years ago on a liner build.
Hope you find the leak. Just be aware that the water pressure will pull the liner down as you fill. So more leaks may develop. Final tacking of the top edge of the liner is usually done with the tank 2/3 full. Bulkheads already installed maybe an issue.

Thanks for the information. Yes, we didn't tack the liner down up top except with some clamps to hold it in place. We did intentionally leave some slack in the liner where the bulkheads were installed... but maybe that wasn't enough. Ill look into other liner builds.. I haven't seen all that many though.... Thanks

Looks good so far.

Sorry about the leak

I don't know whether anyone has mentioned, but checkout stingray keepers' 1200 gal epdm liner build. Is done with liner and was a success and is still up and running. He made it very smart but also covered it with a diy background to hide liner creases etc.

Yes, I've seen that one. It's a good one. I believe he did each piece of wood separately with liner. I was hoping to just drop the liner in.... anyway back to working on it

After trying and trying to get the liner to hold water, we never could findout where it was leaking from. We decided to change plans and rip the liner out. We did however leave the window in.

What's the plan now?

Think the liner was best idea unless you got some sort of water proof cement plaster

The liner was cut up, I think that was the source of the leaks

I always love seeing updates on this thread. Thanks for posting regularly with the progress of this project.

Check out polyurea. It is used to waterproof water tanks, etc. if I was doing a build, this is what I would use. There are threads on MFK that discuss polyurea.

Epoxy as of right now
