01
Hong Kong–Zhuhai–Macao Bridge
The world's longest sea crossing. Our waterproofing materials were applied in one of the harshest marine environments a coating can face — salt, heat and permanent humidity.
Projects & certifications
Projects, patents and certifications
Evidence, not adjectives: the landmark Chinese projects our products have been used on, and the patents and certifications behind the formulations you would be producing.
- Invention patents
- 5
- Management systems
- ISO 9001 · ISO 14001
- 02
Baicheng Tunnel
Tunnel structures leak from every side, which is why they are the classic proving ground for crystalline and cementitious waterproofing systems.
- 03
Hongping Pumped Storage Power Station, Jiangxi
Hydropower infrastructure holds water against concrete around the clock. Waterproofing here is structural, not cosmetic.
Overseas partner case studies will be added as the first partners go into production — country, products, output and the partner's own words.
