The challenge given to this team of Brigham Young University engineering students seemed like a mission impossible. They were asked to create a sustainable building material for people living in impoverished villages in Mozambique. The catch? It had to be made from resources readily available at little or no cost. Also, the material would be required to withstand harsh weather conditions during the monsoon season.
The students from BYUs Fulton College of Engineering and Technology worked with Care for Life, a nonprofit based in the United States and Mozambique. They ended up choosing a cheap building material from an unlikely source: termite mounds.
Termites, which are most often associated with destroying construction, not aiding, turned out to be the solution to a pressing problem. Soil used for bricks needs to be at least 15 percent clay, but the soil in the targeted areas in Mozambique is mostly sand. Termites, though, apparently love clay, because the soil from their mounds is a whopping 75 percent clay. In addition, mounds are accessible close to almost every targeted village.
