Water-filled Rubber Dam is a flexible dam bladder made of high-strength synthetic fiber fabric reinforced with weather-resistant rubber on both sides. By filling the bladder with water, the dam body expands and rises to retain water, achieving water storage and raising the upstream water level. When drainage, sediment removal or navigation is required, the water inside is released and the dam collapses completely, restoring the river's original flow section.

Compared to air-filled rubber dams, the water-filled type offers better stability and stronger resistance to wind, waves and ice, making it suitable for projects with higher dam heights and more complex flow conditions.

Key Features:

Simple structure, low construction cost, short installation period
Good sealing performance, minimal leakage
Strong flow capacity after collapse, minimal impact on flood discharge, sediment removal or navigation
Good seismic performance due to flexible structure that adapts to uneven foundation settlement
Low maintenance cost, service life of 20-30 years or longer
High level of automation available with remote monitoring and control systems

Applications:

Agricultural irrigation and diversion, raising upstream water levels
Urban river impoundment, landscape water storage and ecological water replenishment
Small to medium-sized water conservancy hubs and hydropower diversion
Flood control, drainage and basin-wide water dispatch projects
Construction cofferdams and temporary water-retaining works
Regulating weirs for wastewater treatment plants
Port and dock water-retaining facilities

Custom sizes, dam heights and pressure ratings are available according to project requirements. OEM/ODM orders welcome.
