Reviving a Bridge with HJ3’s Concrete Pile Repair and Strengthening

In a complex and critical bridge restoration project, HJ3 Composite Technologies was tasked with repairing and reinforcing a structure that included 93 concrete piles and two reinforced trusses. This challenging job required precision, expertise, and the use of advanced materials to ensure long-term durability. Working above and below the waterline, HJ3 successfully revitalized the bridge's structural integrity.

The project involved a dedicated team of certified installers who worked both above and below water. The process began with the removal of deteriorated concrete, followed by thorough cleaning and preparation of the piles and trusses. A dual-phase approach was used to address the entire structure—ensuring that every part received the attention it needed for lasting strength.

HJ3 utilized its cutting-edge carbon fiber and CFRP (Carbon Fiber Reinforced Polymer) materials to reinforce the bridge. For the portions of the piles above water, an additional UV and pH-resistant coating was applied, providing extra protection against environmental factors. This combination of high-performance materials and expert application helped restore the bridge to its full structural capacity.

Design: HJ3 follows industry standards such as ACI-440.2R-08, ensuring that all externally bonded FRP systems are designed and installed to the highest level of quality and safety.

Strength: Every system is rigorously tested to meet ASTM D3039 standards, guaranteeing reliable performance even in harsh underwater conditions.

Galvalume Steel Sheet

Galvalume Steel Sheet has excellent characteristics: strong corrosion resistance, 3 times that of pure Galvanized Steel Sheet; the surface has beautiful spangles, which can be used as building exterior panels.
The corrosion resistance of "Galvalume Steel Plate" is mainly because of aluminum, the protective function of aluminum. When the zinc is worn away, the aluminum forms a dense layer of aluminum oxide, preventing corrosion-resistant substances from further corroding the interior.
