Waterproofing For High Speed-Rail
2015 Hubei high-speed rail waterproof project uses polyurea coating, anti-vibration & acid rain, solves railway concrete leakage in humid subtropical climate.
Basic Project Info
Location: Hubei, ChinaCompletion Year: 2015Protective Material: Polyurea Coating
Project Background
Hubei has a humid subtropical climate with prolonged rainy seasons and acid rain. High-speed rail facilities endure constant vibration from running trains, frequent temperature shifts and long-term groundwater erosion. Traditional waterproof materials crack at seams easily, triggering structural leakage and regular railway maintenance shutdowns.The client required a durable, vibration-proof waterproof protection solution for rail concrete structures, and polyurea coating was adopted as the core protective system.
Core Advantages of Polyurea Coating for High-Speed Rail
1: Integral seamless film without joints, completely removes leakage weak points
2: High elasticity and crack-bridging performance to withstand long-term rail vibration
3: Excellent acid rain and groundwater resistance, stable under alternating hot and cold weather
4: Great impact & abrasion resistance, fits heavy-load transportation infrastructure
5: Long service life, reduces railway full-cycle maintenance costs
Project Value
Since completion in 2015, the polyurea coating layer delivers stable waterproof and anti-aging performance under Hubei’s humid climate and continuous rail operation. It effectively eliminates infrastructure seepage risks and guarantees safe high-speed rail operation.This polyurea coating solution suits high-speed rail tunnels, bridge decks, subgrade and all transportation concrete structures.
