I'm planning on building a compost pile out of cinder blocks. Something similar to this. I've seen plans that include driving metal posts through the holes in the blocks for stabilization. How and does this work? It seems to me that the blocks could still move because the posts are too thin and wouldn't touch the blocks. Would I have to fill the holes with something? via /r/DIY https://ift.tt/2Q6Jg8E
