Product Description

T004 30 Years Long Service Life High Quality Finest Price Inflatable Water Filled Dam Rubber Water Dam For River


Main Advantages of Rubber Dams

• Flexible weir structure, allowing discharge of sediments, debris and ice
• Fully automatic reservoir level control
• Self-acting flood release; the automatic bucket drive lowers the weir without the need for external energy to power mechanical valve drives
• Ideal for creating reservoirs in wide rivers; single spans of up to 100 m are feasible
• Renovation and reconstruction of existiing weir structures, regardless of shape and geometric configuration, factory made as a single unit. On site this ready-made membrane just has to be secured in place by the clamping system
• Absence of mechanical components eliminates corrosion risk
• No lubricants needed - protects the environment
• Low maintenance costs and low operating costs due to minimal energy requirements
• More than 100 examples built since 1991

Available Sizes:  

Height can be designed with a range of 1-8 meters.
Length can be 1000 meters, even longer.
