Just a follow up on this post and some new questions.
I fixed the wall with the Hydro Seal as Pieter suggested and painted. Still looking fine.
[You must be registered and logged in to see this image.]I have added the extra step in my waterfall and it actually looks very nice. I need some ideas to build some "containers" on that "step", out of the way of the strong flow to plant some plants. Perhaps even against the top part of the wall. It will need to have a hole in the bottom for water to flow through.
Any ideas? Perhaps print, draw and scan.
What plants can I use? (waterfall faces south). Does one need to put soil in or just some gravel?
On the 'step' I thought to build two "walls" on both sides of the stream. I will take that container away.
