If you've ever wondered how best to provide shelter to large numbers of people in the shortest amount of time, wonder no more. The concrete canvas is the newest innovation in the world of SHTF shelters, and you'd better believe you're going to want to see it for yourself below.

Ever see an idea that is so overwhelmingly simple yet brilliant at the same time and find yourself thinking “Damn! I should have thought of that!” Yeah. That's the concrete canvas.

After all, it's essentially just a waterproof layer of canvas with concrete impregnated fabric riding on top of it. Just add water and voila! You've got yourself a permanent structure.

The applications are endless, and we look forward to seeing just how far this new innovation gets, not only in the prepper world but in the thoroughly modern world of architecture.
