Where Our Dams Work
Rubber dams excel with short construction cycles, long service life, easy operation & maintenance and strong seismic resistance — on reservoir spillways, river weirs, canal systems, tidal reaches and construction cofferdams, across water conservancy, agriculture, municipal and ecological projects.
Eight Proven Fields of Application
Each application has its own hydrology, climate and operating pattern — we match dam type, filling medium and anchoring to the site.
Irrigation
Raise river and canal levels for gravity diversion, and ration water bay by bay through the season.
Hydropower
Add generating head without a concrete barrage — and drop the crest instantly on turbine trip.
Flood Control
Hold a working pool in dry weather; collapse flat to return the river to its natural flood section.
Landscaping
Hold urban waterfront levels with a clean overflow crest and no machinery on the waterline.
Aquaculture
Keep pond and cage depth inside a narrow band, and draw down in stages for harvest.
Water Supply
Keep the intake head submerged through dry spells while environmental flow passes downstream.
River Regulation
Re-wet degraded channels, dilute pollution loads and flush sediment on a store-then-flush cycle.
Canal Networks
Act as head gate, distribution gate or regulator — a repeatable level without gate crews.
One Structure, Many Duties
A single rubber dam can serve several of the functions above at the same time — and be matched to local climate, from tropical monsoon to severe-cold winters.
- ✓Adjustable retention height — 0.5–6 m, raised or lowered on demand
- ✓Full-section flood passage — the bag collapses flat onto the foundation
- ✓Cold-region proven — brittleness temperature ≤ −30 ℃, ice-safe designs
- ✓Construction cofferdam — a movable cofferdam whose height is adjusted instead of building an earth weir, keeping the riverway clean and shortening the programme
- ✓Coastal tide gate — no seawater corrosion and no marine growth, so it outlasts a metal gate on the same site
- ✓Retrofit friendly — upgrades existing rubber dams and flap-gate dams
Beyond the Dam Itself
The structure is only half of a working scheme. Installation and rehabilitation are handled by the same teams that build the bags.
Rubber Dam Installation
Survey, foundation and anchorage interface, bag placement, commissioning and operator training — with hold points at every stage.

Condition assessment, bag replacement, anchorage retrofit and control upgrades for dams that are still structurally sound.
