Putting up a building takes a long time. You need to lay a foundation and then slowly stack your materials up. Not so with Concrete Cloth. Called "a building in a bag," it can be turned into a solid structure in mere minutes.
Essentially, it's like a tent that's blown up with a compressor. But once it's up, it can be sprayed with water to be solidified into a solid structure that's waterproof and fireproof. It's perfect for situations like disaster relief when time is of the essence. Just check out the below video to see it in action.
