——Special System for Concrete Base Layer's Bridge and Road Paving、Used in more than 100 bridges in China
What is KEYUE® WP-100 MMA Concrete Base Layer (Bridge and Road) Waterproof and Anti-corrosion System?
The System is for Concrete Base Layer is specially designed, developed and applied by Shenzhen Zhenghao High-tech Materials Technology Co., Ltd. (Guangdong Zhenghao Transportation Materials Technology Co., Ltd.). It is for high-speed railway bridges, urban rail transit bridges, highway bridges, cross-sea (river) bridges, Water conservancy facilities and dam, steel structure colored steel roofs and other important buildings Provide High-quality multi-way long-term structural protection. The waterproof layer is composed of grass-roots treatment agent (Cement base - Acrylic closed Paint, Steel Base - Acrylic Anti-corrosion Paint) and Methyl Methacrylate Resin waterproof Layer.
In transportation infrastructure construction and maintenance, ensuring the long-term durability and safety of bridges, roads, and other facilities is crucial. To meet the specific needs of the transportation industry, we have introduced a high-performance MMA (methyl methacrylate) waterproof and anti-corrosion coating system designed to extend the service life of transportation facilities.

Application Scenarios:
◉footbridge and flyover's concrete surface
◉ urban hub overpass and Highway's concrete surface
◉ high-speed railway, intercity railway, rail transit bridge steel bridge's concrete surface
◉ bridge anchor, maintenance road, sling area, non-motorized lane and other bridge surface parts
◉ Water conservancy facilities and dam
◉ Building roof, balcony roof waterproof and leak-proof
◉Repair and transformation of damaged polyurea, polyurethane, asphalt coil and other waterproof layers
Structure Shown:
The waterproof bonding layer is composed of acrylic anti-corrosion paint, methyl methacrylate resin and acrylic resin binder. It is applied to the surface of the substrate after mechanical or manual mixing, which can be quickly cured to form a dense elastic protective film with excellent performance, providing high quality for concrete, steel and other substrates. High-quality and durable waterproof, anti-corrosion, tensile, pressure-resistant, impact-resistant, wear-resistant and other aspects of protection and protection have been applied to more than 100 bridges and roads in China and have been unanimously praised.
Why is KEYUE® WP-100 MMA Concrete Base Layer (Bridge and Road) Waterproof and Anti-corrosion System?
Product Features and Advantages
1.System design reasonable, with good adhesion between layers and long-lasting waterproof durability.
2.High tensile strength, tear strength, and compressive strength to withstand various vehicle impacts and vibrations on the surface.
3.Good flexibility and elasticity to accommodate deformations and vibrations on the bridge surface without cracking.
4.Dense coating with strong adhesion to the base surface, effectively isolating water, chloride ions, acids, alkalis, and oils from penetrating and corroding the base surface.
5.Excellent high-temperature resistance, preventing delamination and cracking under vehicular pressure in hot summer conditions.
6.Excellent weather resistance, allowing long-term exposure to air without requiring any protective layers, with no surface cracking, blistering, or peeling.
7.Directly applied under railway ballast as a waterproof layer, eliminating the need for a concrete protective layer.
8.Submerged in (salt) water for extended periods to protect underwater concrete structures and prevent ice impact damage to water structures.
9.Fast curing with a short curing time, allowing for low-temperature application and wide construction adaptability
Success Stories
Our MMA waterproof and anti-corrosion coating has been successfully applied in numerous highway bridges and urban road projects, significantly extending the service life of the facilities and reducing maintenance costs. For instance, the Jining Liangji Canal Bridge, Liuzhou Shuangyong Bridge, Liuzhou Weiyi Bridge, Tianjin Tuanbo Bridge, Xiamen-Zhangzhou Sea-Crossing Bridge, Ordos Hantu Bridge, Ma'anshan Yangtze River Bridge, Tongling Yangtze River Second Bridge (He-Fu Railway Combined Road-Rail Bridge), Chongqing Egongyan Yangtze River Bridge, Tengchong Longjiang Bridge, Pingtan Strait Bridge, and Lihua Expressway Jinsha River Bridge have all used our waterproof bonding layers, maintaining outstanding performance under harsh climate conditions and earning high recognition from clients.
