Shelter in 24hrs: An Emergency Concrete-laced Canvas Tent

From National Geographic’s I Didn’t Know That, this flexible, concrete-laced canvas can be put up by two people and ready to use as shelter within 24 hours. It’s essentially a building in a bag.

With water to activate the concrete and air to inflate it into shape, the concrete hardens into a solid structure that resists fire and water. It can even become a sterile, hospital-like environment, an essential need in humanitarian crisis situations.
