[Cob] Large Gravel-Filled EarthBag Foundations - Off Topic and More!Ocean Liff-Anderson ocean at woodfiredeatery.com

A few points: 1.) Seems you've gotten the "I hate concrete" philosophy down, but why? Because it isn't natural? Neither are gravel (intensive industrial product) filled bags, nor fiberglass (even more industrial and carbon-emittive) rebar spikes. Then there's the petro-slurping tractor to do all the heavy lifting. 2.) Do you have any idea how much a one-yard bag of gravel would weigh? Last I checked a yard of rock weighs 3500 pounds - yep, almost 2 tons. Doubts any forklift or tractor bucket could lift that without destroying its hydraulics. 3.) Ever tried spiking anything into compressed rock before? I doubt a fiberglass rebar would be able to penetrate the rock, and certainly would splinter with dangerous consequences - be sure to wear eye- protection, heavy gloves, coveralls to avoid the flying fiberglass shards. 4.) This whole thread is way off-topic for this list - where's the cob here? Maybe you'll plaster with cob?
