What about 2 concrete (cinder block) instead
I've read that cinder blocks can crumble under load. That would be a great option otherwise.
They use cinder blocks under mobile homes all the time.
You could stack 2 cinder blocks side-by-side and put 2 more on top the same way, then lay a piece of 2x6 on top of the blocks.
You can also buy ''solid cinder blocks''.
