There was a time when homes across India were built with concrete slabs over a skeleton structure made with iron rods. However, the rods would start rusting soon after construction was over, affecting structural stability of the buildings in the long run, and requiring frequent repairs. Besides, the 1993 Latur earthquake, which leveled a village and its surrounding regions and caused more than 30,000 houses to collapse over their unfortunate occupants, made it clear as to how helpless people with such homes were in front of the wrath of nature. A solution was needed, and fast!
For many years, engineers across India used twisted iron rods to build skeletons of homes. While these seemed to create quite a strong structure for homes during the construction, soon afterward they would start corroding in contact with the moisture from the concrete. Naturally, houses had to be repaired every few years, and even then, had a hard time standing up to natural disasters like earthquakes. However, not many deaths occurred due to collapsing buildings, since the earthquakes themselves were low in magnitude.
