Thread: Building a small koi pond waterfall.

Not knowing where else to post this , I chose gardening, if need be, please move to appropriate sub forum.
I mentioned on another DIY I was planning to build a small waterfall for my koi pond ,so below is my process . successes, and mistakes.
I had a hard time finding rocks in Khon Kaen , anyone who knows the area knows that there is nothing but red clay here. So I had decided to make my own faux rocks out of cement and pigments, but the other day while we were visiting my now deceased father in law's farm to decide what we were going to do with it. I noticed that there was a train track running on the side and the embankment was lined with large chunks of granite so I decided to use that.

First I build a table out of common cement block , I laid a piece of wire lath on it , temporarily supporting it in the middle so as not to sag in the middle, and gave it a scratch coat ,to stiffen it up. when the scratch coat had dried sufficiently, I laid some re-bar on it , and laid a couple of more inches of cement to make a table top , and support the wait of the rocks
