Bahareque

 

I have friends in many parts of the world interested and / or building with various forms of green building. I share my bahareque experience with some photos and brief writings, as we did with the superadobe construction. Here are photos and a video to further clarify the process of building with bahareque.
 

We have been building with super adobe. The first three rooms are already finished.


Super adobe consists mainly of free material but it is very intense work. Therefore, we are going to make the bathroom, which is an external corner between two hexagons, with a wall of baharequeBahareque a traditional Mexican method that uses a structure of reed filled with mud or "cob." Bahareque is very similar to the technique of "wattle and daub" of medieval England.
 

 

I cut more oaks from the forest for the firm structure. They are anchored to a conventional concrete, gravel and rebar foundation. Between the firm oak beams we put a reed structure, which we also cut on our land. Then we are going to fill the reed structure with cob, a mixture of mud, sand, and straw.
 

I saw some videos on wattle and daub and a few examples in the houses nearby. They usually use mud. I decided to use cob, adding straw and sand to the mud. It has better consistency and you can add larger balls without them falling apart. Therefore, it is not only faster building with cob but also stronger.
 

 
 

 
 
You can see in the photo of the window how the cob is very smooth and does not really need a top coat inside the house. On the outside we will put a very fine layer with the same mixture of clay and sand, only with a little lime. The lime prevents that the wall does not wash away if it is stuck by driving rain. The dry parts of the wall reveal the final color, whiter than the earth without lime. In our mountain there is brown, red, yellow and purple clay and we could vary and / or mix these colors but I like the beige of the brown earth bleached with lime.
