Bitumen is the oldest design material that we know about, and it has been used as cement, as a sealant, and as a waterproofing specialist starting from the dawn of history. A flourishing shipbuilding industry existed in Sumeria as far back as 6000 BCE, and it utilized the normally happening bitumen that could be tracked down in surface leakage in the district. An especially very much protected water tank tracing back to around the year 3000 BCE can be found in the Indus Valley, which is currently in the nation of Pakistan. Normal bitumen is utilized to tie the stone blocks that make up the walls of the tank, and there is an upward bituminous centre that goes through the centre of each wall. The development of current dams sticks to a similar essential thought. There could be no other structure material that can contrast with the flexibility of bitumen.
