Superadobe, I am Your Father
I believe it was Christopher Nolan who said “Batman and Superman are very different characters but they’re both iconic and elemental.” Either way you cut it, adobe is elemental, and adobe is nothing new; I make the comparison the Batman and Superman because they are both superheros, however different…
Adobe is also something nothing short of super. From the ancient Egyptians to the Anasazi Tribe, many cultures near and far have utilized the brilliant mixture of straw, soil, sand and water tamped together to create a sun-hardened earth house for shelter through the ages. These homes are sturdy, cool on the inside in the heat of the Sun, and warm on the inside during cool nights.
It is quite possibly some of the most amazing architecture that we can find when we look at the history of our progression of architecture, next to the great pyramids and cliff dwellings. Let’s face it, in many parts of the world, because of its magical simplicity, adobe is, after caves, how humans survived the elements.
Superadobe is Born Powerful
In the present, an Iranian born architect, Nader Khalili, has discovered, well- I say present, but it was some twenty plus years ago- how to perfect the concept of adobe and bring it forward into the new age. Through modification of the structural processing of the staging of the adobe, Khalili has managed to create a product and process that he has coined as Superadobe. Khalili has said that “Superadobe is an adobe that is stretched from history into the new century. It is like an umbilical cord connecting the traditional with the future adobe world.” He has an interesting take on adobe and its re-emergence to the “new world” through his superadobe product.
Moon-dust or Sand. Take Your Pick – it is Still Super.
What this really means is that his process of taking long tube-like bags, usually made of sturdy polypropylene or sometimes straight-up burlap, and filling them with sand, or rice or any sort of fill, then creating a trench for the foundation, and forming the frame out of these tubes which are filled with the “fill of choice” and then tamped down, either by hand or with a pneumatic tamper. As the foundation is created, windows can be created by having voids not filled, or cut out after the fact. A huge part of superadobe, beyond the tubular filled bags of soil or the like is the barbed wire which reinforces the shape of the buildings, which are generally a coil of these reinforced tubes which ultimately form a beehive shape. There have been extensive experiments with the concept of superadobe, or the earthbag building concept, which Khalili first came up with after attending a symposium at NASA in 1984 where he was trying to figure out who to build structures on the moon! Imagine, bags full of moondust. That sort of sounds magical, or super! Doesn’t it. Just agree. It does.
From the Moon to Your Backyard it seems that not even Kryptonite will take this stuff down! Superadobe is one sturdy building concept. It is aerodynamic, just as its predecessor, just regular old adobe is. However; with the beehive and or rounded edges that it tends to take on, it can survive hurricane force gales. A superadobe home or building can be built by unskilled labors in a matter of days by the resources available on site, either of the sandbags, or of the specific tubing and barbed wire. The buildings are sturdy, sustainable, cost effective and can be built in nearly all elements. As a builder, one would look to superadobe from the cost effective standpoint for a client who is thinking about passive solar design; it tends to stay cooler during the day in those hot climates, and warm in the evenings in cold climates. The stuccoed exterior is incredibly low maintenance and provides the client for an exceptional opportunity for reduction in utility bills, or for even being off the grid, if they so desire. New offices looking for an interesting, cost effective and sustainable building concept, could certainly look at superadobe as an option. The unique building structure of the circular and hive-like shapes lend towards something new and different. If you want to stand out from the crowd, be sustainable, and possibly have a quick build, superadobe could be for you. It From the moon to Costa Rica and everything in between, superadobe is a sustainable building concept that has green building aficionados looking towards the sun. It’s a bird, it’s a plane. No. It’s superadobe.
