Rubber dam is made of high-strength synthetic fabrics and compound rubber, anchored in the concrete foundation to form a sealed air bladder inflated with water or air in dry seasons to store water. In rainy seasons, water or air inside of rubber bladder would be discharged to help release floodwater from river course. Compared with common civil works, the advantages of rubber dam are less engineering budget, shorter construction period, extended service life, simplified maintenance and improved vibration resistance. Rubber dam can be adjusted at any height and overflowed so it is widely used for irrigation, power generation, flood control and urban landscaping in many areas.

The rubber sheet for the dam tube is made by calendaring and vulcanizing canvas and rubber material. The canvas serves as the force-bearing frame of the dam, and is made of chinlon *6 with high strength, good flexural stress resistance and excellent adhesion function. The rubber connects and projects the canvas layers, and is distributed in outer-layer, middle-layer and inner-layer.

Outer layer

It possesses good resistance against wear-and-tear, sunshine, heat, cold, ozone, corrosion and water. It is thicker than 2.5mm.

Middle layer

The middle layer is used for protection of canvas and for connection of 2 or more canvas with rubber layers.

Inner layer

The inner layer is used for protection of canvas and characterized watertight and airtight features.
