Cool sandbag info, got my wheels turning. Wondered for a while now about Hesco Bastions Concerntainers that our military uses. They are also used a lot back in Louisiana for levees, erosion and such. I think you could make a damn fine and dandy house with those. Bullet resistant, bomb resistant, radiation resistant, you name it. Throw some stucco, adobe, shotcrete, whatever...that could be down right homey.
