I’m building some cabins and don’t want to go the sono tube route. I’ll probably just fill them with rocks. Is there anything other than stone that I can put in there that I can salvage from construction sites? Broken brick seems too easy. Must be a catch. Anything that takes up space and won’t compress too much. Hope everyone is having a great start to the year.

it is too deep to freeze, i don't think there would be an issue with brick or an old cut up slab. I think the reason for stone is that is always available in whatever quantity someone wants, so that is the standard.

bricks take a lot of compression, think of the weight of a chimney on the bottom bricks.
