I was surprised on my morning run yesterday to see what was once a dusty parking lot for songtaew suddenly transformed into the makings of a park and pond. This literally happened in a single day:
I'm amazed at the way they're building this. Nothing but bricks and mortar. No steel. No wire mesh. Nothing to reinforce the structure.
I once built and in-gound hot tub using ferrocement. I used rebar around the edges where people would be standing or sitting and plenty of wire mesh throughout. Still, after eight or nine years and after the invasion of tree roots the thing developed hairline cracks which leaked and had to be repaired with Thoroseal.
It seems to me that it won't take long for this new pond to develop some cracks which will leak like a sieve.
I guess that's why I'll use flexible pond liner for the pond in my new house.
Anyway, here's the happy construction crew after a long day's work.
