Natural rubber Expansion Joints, Brand Name : jianfeng

Description
inflatable rubber dams are air-filled or water-filled rubber membranes attached to a concrete foundation. In a filled (or raised) position, they act as a barrier to hold back water to be used for irrigation or to generate hydro-electric power. They can also be used to control flood-water or as tidal barriers between an ocean and a river.
 
air-filled or water-filed flexible membranes are attached to concrete to create a permanent, dam or floodgate. Made of high quality uv resistant hypalon rubber compound reinforced with high-strength polyester fabric. Flexible dams offer full flood control with the ability to fully open or fully close very quickly. Floodwater or flash flood will spill over the top automatically without additional support or adjustment.
 
the proposed inflatable dam would divert water so it could recharge camp pendleton's aquifer, replacing a metal weir that's clogged with sediment. It would be roughly 7â½ feet tall and deflate during floods, allowing the waterway to replenish the coast with sand and letting fish pass through.
