[Case Study] "Backing Plate Method" in Bridge Repair × Wear-Resistant Metal for Extended Lifespan
KAN paste
Suitable for the plate method with metal putty! 'KAN Putty Wear-Resistant Metal' can simultaneously expect adhesion, corrosion resistance, and wear resistance.
The "patching method" for repairing aging bridges is a practical technique that minimizes traffic impact with short construction periods and partial work. The key to success lies in selecting a metal putty that enhances the adhesion between the base material and the patch, equalizes stress transfer, and contributes to waterproofing and corrosion resistance. ■ Why is metal putty necessary? - Improved adhesion between the patch and the base material: Fills in irregularities and defects to create a uniform contact surface. - Ensured adhesion and durability: High adhesion, water resistance, and chemical resistance prevent long-term peeling. - Efficient stress transfer: Fills gaps to avoid stress concentration and stabilize reinforcement effects. - Waterproofing and rust prevention: Blocks the intrusion of moisture and air to suppress corrosion progression. - Improved workability: Easy to shape on-site and cures quickly, contributing to reduced construction time. ■ Wear-resistant Metal In this case, we introduce the repair using "KAN Putty Wear-resistant Metal," a metal putty repair material recommended for waterproofing, corrosion resistance, and repair linings that require high wear resistance, with a high content of alumina ceramic powder. It achieves reliable repairs in a short period, even for components with advanced corrosion, minimizing traffic regulation time. It contributes to both extending the lifespan and ensuring safety within limited budgets and personnel. ■ Construction Examples For more details, please refer to the "Detailed Information" section at the bottom of the page.

■Case Study Introducing the "Backing Plate Method" for bridges using "Wear-Resistant Metal."
-
■Case Introduction Repair material used in this case: KAN Putty Wear-Resistant Metal
-
■(1) Construction Area Water may infiltrate the steel parts due to rainwater and humidity, leading to corrosion and deterioration. We will use "wear-resistant metal" to fill the gaps in these corroded areas with putty.
-
■(2) Putty filling work (enlarged photo)
-
■ (3) Overall Putty Work Fill in dents and cracks to finish the entire surface uniformly and smoothly. This work creates a base that enhances adhesion to the backing plate.
-
■ (4) Fixing the backing plate Quickly attach the steel plate before the putty hardens and secure it firmly with bolts. By attaching it before the putty hardens, the adhesion between the steel plate and the base material is significantly enhanced, allowing for a highly durable repair. Through this process, even bridge components that have experienced corrosion or wear can be reliably repaired in a short period, minimizing traffic restrictions.

Company information
The roots of Kansai Paste Chemical date back to 1907 with the production of gofun (shell powder). We have challenged ourselves to create products that meet the needs of the times, and now we manufacture and process a wide range of products beyond just paste. In particular, we possess many manufacturing facilities for medium to high viscosity products and are also equipped to handle small-scale packaging.
