On the heights of Bogota, curious rise igloos. Gifted with good thermal insulation and resistant to earthquakes, these dwellings are not built with ice but with old tires abandoned. These residues are a real environmental pest in Colombia. Thanks to this project, have been recycled materials construction.
Pioneer project in Colombia, Alexandra Posada, an environmental activist, has organized the construction of original buildings in round walls in the town of Choachi , about 40 kilometers from the capital. “I give away these tires because it is a huge problem discard they. It takes thousands of years to decompose, “says this 35 year old woman who oversees the work in jeans and cowboy hat.
“Used for construction, become virtually eternal bricks “he adds. To convert tire blocks compact of 300 kilos, they are filled with earth. Iron bars are sandwiched between the tires of various sizes, depending on whether they come from trucks or cars.
This technique, which takes advantage of the flexibility of rubber, allows these houses cling to the side of the hill in the cook of the Andes, and so deal with the movements of the Earth, very common in this region.
The roofs of these houses are made of cement room and the kitchen, and wood for the dining room, an aesthetic issue. The roof is covered with tires that serves as shingles.
