Standards for clay construction

EcoSouth colleagues are working out proposals for standards for construction with clay. The first preoccupation is the question: "What has to be subject to standards?" Many think that the resistance of a clay brick to compression is the critical route, but it is scientifically known that in a wall it is not the brick that fails; rather almost always it is the meeting between the elements. Javier Quiñonez, director of investigation at the University of San Carlos in Guatemala, is perfecting a simple system that he has been using to measure the resistance to horizontal (shearing) forces in walls.

In 2005, SofoNic has started a dual education program for masons in Nicaragua, using its house-building programs as a base. Teaming up with the local technical school in Jinotepe they are graduating about ten masons every year since. Most f them have found jobs in construction or have started a business on their own. SofoNic has contracted several of them as master masons in the reconstruction programs in Haiti.
