What types of rubber dams can we supply?

Inflatable rubber dams are manufactured from high-strength synthetic fabrics (especially nylon canvas) and multi-layers of rubber with good and excellent resistance against weather, abrasion and ozone. Since the first inflatable rubber dam was installed in Los Angeles County in US in the 1950s, the rubber dam swept across the market quickly as a novel water control structure with high cost effectiveness.

Types of rubber dams

Our company specializes in manufacturing and exporting quality inflatable rubber dams for over ten years. Our main products include air filled rubber dam, water filled rubber dam, bookend rubber dam and shield type rubber dam in a wide range of sizes for different applications such as hydropower, flood control, irrigation and water retaining.

Air filled rubber dam a cylindrical rubber weir filled with air, can be inflated and deflated easily and quickly just using air blowers. Meanwhile, it needs narrower concrete foundation for installation and lower cost for daily operation.

Water filled rubber dam is slow to fill, yet features minimal vibration taking advantages of high weight of water. In addition, it provides a higher overtopping about 50% of the dam height and better to be suited to applications where there is a tail water elevation and board watercourse.

Bookend rubber dam features added spines to heighten the water head, minimize vibrations and eliminate vacuum underneath of the dam. In addition, bookend structures make the dam excellent in abrasion and impact resistance.

Shield type rubber dam, composed of air filled rubber bladders and steel shield plates, is characterized by modular design for easy installation, adjustment and repair. It's suitable for channels and spillways in any span regardless of sediment, bedload and floating debris.

Except above inflatable rubber dams, our company also supplies automatic control system, clamping plates and anchor bolts for easy operation and installation.

Why choose us?

As a specialist for manufacturing inflatable rubber dams, we can provide quality products, custom designs as well as superb services to every customer. Most of all, our products are low cost, easy to install, operate and maintain with a long service life. Here are the unmatchable features and benefits of our products.

• Reliable inflation and deflation states
  The inflatable rubber dam can be filled with air or water to designed height and pressure to store water during dry season. In rain seasons, air or water can be pumped out of the rubber dam quickly and easily to prevent flooding during high flow.
• High resistance to sedimentation
  Water may not flow by the excess dirt, boulder stones and sedimentations. But these will not trouble the inflatable rubber dam because all these sedimentations can be washed away when flexible rubber dam is deflated.
• Easy and quick to install
  No matter what size of the dam, the inflatable rubber dam delivered to the site is only one piece and ready to install. Therefore, only a short construction period is need to install inflatable rubber dam. In addition, single spans in width of over 100m may not need intermediary concrete piers which enhance flow characteristic and cost lower for associated civil works.
• Easy to operate
  Adopting advanced self adjustment system, the inflatable dam can be inflated and deflated automatically to control the height and pressure of the rubber dam according to water levels of upstream.
• Lower construction & maintenance cost
  Installing inflatable rubber dam is a economic choice for water flow control as it saves 30% to 70% cements, steels and woods comparing with conventional concrete dams. Additionally, the rubber dam is ease of maintenance using minimal cost as there is few moving part.
• Longer lifespan
  The characteristics of excellent resistance to shock and abrasion make the dam capable to last longer about 15 to 30 years.
• Suitable for any span
  Inflatable rubber dams are suitable for various types of sites especially where the width is larger than height. Whether it be long or short span, the dams can be installed without piers, while the concrete dams need piers every 15 to 30 meters.
