Waterproofing Of Hydropower Station Dam
2018 Jilin cold-region hydropower dam renovation uses polyaspartic waterproof coating, anti-freeze-thaw & reservoir medium corrosion for water conservancy facilities.
Basic Project Info
Location: Jilin, ChinaCompletion Year: 2018Adopted Material: Polyaspartic waterproof coating
On-Site Difficulties
Located in northern China, Jilin suffers long cold winters, extreme temperature differences and recurring freeze-thaw cycles. The hydropower station dam stays immersed in reservoir water all year, with sediment and ion corrosion constantly damaging concrete surfaces. Traditional waterproof layers crack and peel quickly after frost exposure, causing dam seepage and hidden hazards for power production.The engineering team chose polyaspartic waterproof coating to deliver long-term anti-freezing and impermeable protection for the dam structure.
Key Performance Advantages of Polyaspartic Waterproof Coating
1: Highly flexible film maintains intact performance under repeated freeze-thaw cycles in cold northern areas
2: Dense coating barrier thoroughly isolates reservoir water, sediment and corrosive ions
3: Great crack-bridging elasticity to adapt slight deformation of dam concrete
4: Strong adhesion on wet concrete substrate, no hollowing or peeling under long-term water immersion
5: Long service lifespan to reduce hydropower station regular maintenance expenses
Project Operation Value
After construction in 2018, the polyaspartic waterproof coating keeps stable protective performance under Jilin’s frigid climate and continuous water soaking. It completely eliminates dam leakage risks and ensures steady safe operation of the hydropower station.This Polyaspartic Coating is widely applicable for cold-region hydropower dams, reservoirs, water conservancy pools and water retaining concrete structures.
