Concrete is less flexible and cracks over time. Repairing an existing water tank is a time consuming process and cause inconvenience to the residents. Cement slurry is supposedly used to waterproof the tank which temporarily arrests the leakage from cracks & joints. Seepage and leakage from overhead and underground tanks spoils the decor, helps growth of algae and fungus and leads to weakening of the structure. Such areas hence need to be waterproofed by our “Supermega Waterproofing Chemical”.
