Global GIAN was inaugurated by Wang Heng, an outstanding farmer innovator. As a poor & hungry person, it pained him to see people using food grains (beans) to plug the leaks in roofs. With 23 years of efforts, he created a waterproof cement-like material, which becomes solid in six seconds when mixed with water. This material has been widely used in key construction projects, including a Beijing subway station, Beijing-Kowloon railway and the Three Gorges Dam. His waterproof technology was also introduced to other countries such as Bangladesh, the Republic of Korea and Morocco.
