How deep should i dig foundation for a fish pond 3 blocks high and 4 blocks long each side
I would just dig a 450 x 450 trench with 150 mm thick concrete. I would recommend you build a double block wall as the weight of the water would push over a single skin shell

Dig down until you reach hard clay or sandy ballast type soil....
