im wanting to put a koi pond in the garden.
It will have a back wall @ 8' long, then a left side @ 5'long and a bowed side to join the ends together.
3' will be above ground.3'below. The inside will be fibreglassed.
I want a window in the bowed side so I can see the fish from the conservatory.
How thick should I make a rebar reinforced concrete base?
Will 3.6n blocks be Ok as a single skin on end, or should I lay them flat?
Thanks for any help.
