Temproary Housing Part 2: Inflatable Concrete

Inflatabe concrete.  Sounds a little crazy and out there, doesn't it?  But it does exsist.  And, in all truth, not a bad idea.  Aesthetically pleasing?  Well, maybe not so much.  Let's a lot of light in?  Nope, not really.  Costly?  Not horrible.  Doable by only one or two people?  Yes.  Durable?  Well, I think that one goes without saying.  It is concrete we're talking about, after all.




Ok, so let's talk about this.  This is a relatively new idea, and one that does have it's merits.  Sometimes referred to as concrete tents or simply concrete canvas, these were originally marketed as fallout shelters and for various military applications.  As of right now, there are two primary companies making these types of shelters.  The first one, is primarily utilitarian.  No windows, a door on each end, pretty much like a bunker.  The other is a little better well designed, having living space as the primary purpose.  It looks more like a house, has more windows, but pretty much goes up just as easily.  Now, if this is going to be a temporary residence for you, this would be a fairly descent option if you are building in tornado alley, as you could easily use it for shelter.  Especially, if you have the foresight and desire to place it at least partially underground.  Or, you could even bury it almost completely and create your own version of a Hobbit house.

The basic idea is that you have a large package of this flexible material.  Soak this material until fully wet to the touch.  At that point, all you need is a good source of air, and a vehicle with a tow cable, or some other source, with which you can unfold the material as it fills with air.  The material itself is a durable fabric that is impregnated with concrete fiber.  Once it is set up and filled with air, it will generally dry within 24-48 hours.  When completely dry, it is said to be both fire and water proof.  It can be, however, thin enough that, with proper tools, can have window openings cut into it.  Check here to see a video of a concrete shelter being put up.

Both versions can have two or more shelters join together for more space.  In that way, it is extremely customizable.  While one manufacturer (here) lists a price of $3,500 per unit, the other manufacturer (here) lists their prices from $23 - $60 per square meter.  They are an international comany, and prices range by region.  They also offer a bit of range in the thickness of the material, as well as offering sheets of the material for other purposes.  They have a link on their site to find and contact a local dealer to obtain more specific pricing information.  There may be other companies out there that also offer a similar product.  As of this writing, however, every site I have found, links back to one of these two companies.

What you get is essentially a blank canvas where your imagination can go wild with uses.  And whereas the appearance may or may not be ideal, it is a genuine option worth considering, whether it be for a temporary residence or something more permanent.  This is an option I would actually consider just due to it's ease and speed in putting it up.  And it could have use down the road as something along the lines of a root cellar, if nothing else.
