Mumbai city has been known to receive heavy rainfall during the monsoons. Being a coastal city, Mumbai needs to understand the requirement for costal construction and heavy rainfall. More than 80% of the pre-1990s construction is in distress because of poor quality material and harshness of environment. Despite all this, Mumbai was one of the last cities to take up blended cement that helps fight problems related to waterproofing.
