It’s nothing new: some of the oldest buildings in the Earth are built with soil. It is estimated that half of the world population lives in houses made with this material.
It’s 100% organic, is neither manufactured nor transported. A wall made of soil stays cool in summer and keep warm in winter. When the building is demolished, returns to earth ground and recycled indefinitely. It is becoming the favorite material for many architects, because of their aesthetic and ecological qualities. The industrial sectors look favorably, for its sustainability.
Obviously, not all soil can be used to build houses. The soil of a forest, for example, would not, because it contains too many organic elements —so its color is black—. And if used needs a compaction process, would be added in the process, among other things and simplify it a bit, some sand, because it will prevent the walls made of earth is cracking.
There are already several earth building techniques like adobe or mud stacking, but we must achieve greater strength as a building material of the future, avoiding the heavy rain, heavy snow and strong winds can damage buildings. Currently, the research is trying to make it more resistant to become a modern and competitive materials.
To get to be a real alternative to other materials such as cement is necessary to spread its benefits in the right circles, and minimize or eliminate their disadvantages, which still has them. Thus, the land will become part of the construction materials of tomorrow… worldwide. Probably all of us will win with the change.
