A Concrete Tent

What happens when you need a structure that’s a bit more permanent than canvas, but also fast-building? Well, this concrete tent might be the answer. You need a lot of water, and air pump, a truck, and about twenty-four hours, and then you get a concrete building.

Is it as good as other portable structures, like Canada’s own Sprung? Tough to say, but it’s pretty neat.
