Hybrid Joints by CRITEC Foster Bridge Safety Across Thousands of Locations

Ensuring Bridge Safety with CRITEC's Hybrid Joint

CRITEC Industries, based in Minato, Tokyo, is a leading manufacturer specializing in bridge expansion joints. The company has proudly announced that its innovative product, the 'Hybrid Joint,' has been adopted at approximately 20,000 locations across Japan. Adhering to the motto 'The power of connection is the power of movement,' CRITEC focuses on safeguarding drivers and pedestrians while enhancing the longevity of critical infrastructure.

What is the Hybrid Joint?

The 'Hybrid Joint' created by CRITEC represents a cutting-edge blend of rubber and metal technologies, delivering exceptional durability and water resistance for bridge expansion devices. Since the launch of sales and installations in 2000, the company has consistently built trust among users, achieving a cumulative installation figure of around 20,000. For instance, the Hybrid Joint L-100 was successfully implemented in Eitai Bridge located in Koto City, Tokyo.

Note on Adoption Figures: The reported number of installations, totaling 59,728 meters, translates to about 19,909 locations based on the average lane width of approximately 3 meters on national roads as of May 2025.

Eight Reasons for Choosing the Hybrid Joint

1. Long-term durability & maintenance-free: Its vertical structure minimizes damage from metal fatigue.
2. Outstanding water resistance: The Hybrid Joint surpasses stringent NEXCO water resistance tests.
3. Comprehensive product lineup: From small units with a 20mm expansion range to large models accommodating up to 600mm, we offer a product for every need.
4. Compatibility with all bridge types: Be it steel, PC, RC, or various bridge designs, our joints are universally applicable.
5. Ultra-low noise and comfortable driving: Minimal exposure reduces impact noise while enhancing slip resistance in adverse weather.
6. Safe and easy installation: Using a 4-ton crane truck allows for safe implementation without heavy machinery.
7. Quick exchange: Many products can be replaced within 8 hours per lane, minimizing road congestion.
8. Economically produced domestically: Our localized manufacturing contributes to reduced costs.

Revolutionary 100-Year Durability Tested in 3LⅡ Type

In 2018, the 'Hybrid Joint 3LⅡ Type' was launched, boasting a proven lifespan of 100 years through rigorous testing by third-party organizations. With endorsements from public agencies like the Ministry of Land, Infrastructure, Transport and Tourism and NEXCO, this model stands as our most sustainable bridge expansion device.

Japan is home to around 730,000 bridges, yet only about 10,000 can be repaired annually. Traditional joints typically require replacement every 20 to 30 years, creating a troubling cycle of maintenance and delays. The introduction of the 3LⅡ Type, with its 100-year durability, effectively addresses these challenges and has the potential to significantly lower lifecycle costs, while also minimizing disruptions from repair activities.

Additional Product Series

CRITEC offers a diverse range of Hybrid Joints, capable of accommodating expansions from 20mm to 600mm. Our solution caters to various bridge types and segments, including roadways and pedestrian paths.

Commitment to Sustainability Through Global Expansion

CRITEC President Yuji Wakabayashi expresses gratitude for the widespread adoption of their products and addresses potential concerns regarding job reductions due to their long-lasting technology. He firmly believes that driving down unnecessary regulations and construction leads to social contributions.

Although it may seem counterintuitive for a manufacturer, the mission remains focused on enhancing infrastructure sustainability.
