The "Rubber Dam" is a rubber weir that has a simpler civil structure compared to other gates, making maintenance easy and maintenance-free. It enables low-cost, high-performance flood control and water utilization. Since the rubber is inflated with compressed air, there is no need for equipment such as hydraulic cylinders, eliminating concerns about oil leaks into the river. Nihon Jidoki Kogyo Co., Ltd. constructed its first rubber-coated fabric weir in 1964 and has continued to install this product at over 530 locations. 【Features】 ■ Can accommodate various river cross-sections and bank slopes ■ Installable in various sizes, from small sizes to long sizes near estuaries ■ Design can be tailored to river conditions and intended use *For more details, please refer to the PDF materials or feel free to contact us.
