Rubber Dam - Adjustable Water-Control Barrier for Rivers and Canals

Looking for a simpler way to hold water and still pass floods safely? A rubber dam may be the answer. It uses a strong bag made from synthetic fabric layers and rubber, fixed to a concrete base. Fill the bag with water or air and it rises to lift the water level. Empty it and it lies flat, so the river flows freely.

Highlights:

Built to last: Layered fabric and rubber stand up to aging, wear, sunlight, and harsh weather
Set the height you want: Filling or draining the bag changes the water level easily
Choose how to operate: Manual, remote, or automatic control is available
Less to maintain: No large steel gates, cranes, or complex moving parts
Budget-friendly: Quicker to build and cheaper than traditional steel or concrete dams
Safe in floods: The flat, empty bag leaves the channel open
River-friendly: A smooth overflow creates an attractive water view with little effect on the channel

Where It Works:
Irrigation and water conservancy projects, hydropower stations, flood control, river and city landscape water features, water storage and diversion, tidal barriers, and seawater intrusion prevention.
