The rubber dams are made of high-strength synthetic fabrics and compound rubber supported by a frame and prefabricated rubber, riveted on the base board to form a sealed bag-shaped space inflated with water or air in droughts seasons to store water for industrial, agricultural and household water consumption. In rainy seasons, water contained in dam shall be discharged to help release floodwater from the river course. Advantages of rubber dam are shorter construction period(3-15days for installation and the final construction period 3-6 months),30%-70% less engineering budget than that of civil works for cements, steel and logs, extended service life, simplified maintenance and improve vibration resistance.

The rubber dam is suitable for the projects with lower water level and large span sluice widely used for irrigation, power generating, flood control and urban landscaping.
