Switzerland are building a dam next to another dam that can no longer be repaired, B1M have a video going over the method - https://www.youtube.com/watch?v=k0vxzYvIHUk

That dam also holds back the largest (as far as I recall) pumped hydro storage system in the world. I’m not sure but I think they talk about it in the video you linked if it’s the same one I watched a while back.

Thanks for linking that. It was a nice half an hour well spent.
