Crittec Industries Co., Ltd. published a newspaper advertisement (black and white, full-page 15 columns) for the bridge expansion device "Hybrid Joint" in the February 26, 2026 issue of the Sankei Shimbun Tohoku 6 Prefectures edition. In Japan, the number of bridges over 50 years old is rapidly increasing, making the longevity of bridges a critical issue. The expansion devices, which are considered a cause of bridge damage, require high water-tightness and long-term durability. Our expansion device "Hybrid Joint" offers multiple types tailored to different bridge types and conditions. Among them, the "Hybrid Joint 3LII type" has demonstrated a durability of 100 years in fatigue loading tests conducted by a third-party organization. It has successfully passed 12 million cycles of repeated loading at a maximum load of 260 kN, confirming performance equivalent to a 100-year design service life for bridges. We have numerous delivery records in the six Tohoku prefectures and can accommodate a wide range of bridge types, including steel and PC bridges. The special website linked to the advertisement allows for the review of detailed materials and inquiries or requests for documents. Please make use of it for comparing and considering bridge renewal and repair plans. Crittec Industries will continue to contribute to the longevity of bridges nationwide, starting with the Tohoku region.

The "Hybrid Joint TCF Type" is a bridge expansion device designed for the Tohoku region that responds to "compacted snow," which occurs due to vehicle traffic after snowfall. It meets the 10kN snow load standard set by the Tohoku Regional Development Bureau. Additionally, it adopts a structure known as the "face plate type," which ensures that the water-stopping material does not become exposed on the surface, and it comes standard with "secondary water-stopping material." By employing a double structure, it reduces the risk of leakage and achieves higher water-stopping performance. Furthermore, to prevent snowplow blades from getting caught on the expansion device, it also comes standard with a "snow removal guide plate." This not only protects the product itself but also considers safety during snow removal operations.

Recently, an article about Crittec Industries' construction achievements was published in the January 1, 2026 issue of the Bridge News. The article highlights a case where, during the concentrated construction of the Meishin Expressway conducted in November 2025, a large finger joint was replaced with our "Hybrid Joint Type 3LII." The background for receiving this construction order was a similar replacement project carried out in 2024 within the jurisdiction of the Kyoto Expressway Office of NEXCO West Japan's Kansai Branch. This construction is noted as the first case in the Kansai Branch area where a large finger joint was replaced with a product joint, and the high evaluation of this achievement led to its adoption in the concentrated construction of the Meishin Expressway. Replacing large finger joints with product joints is a field with few precedents and high technical difficulty, leading many companies to hesitate in responding. In this context, our Hybrid Joint Type 3LII, which possesses reliable technical capabilities and construction achievements, was selected. For any inquiries regarding expansion devices, please consult Crittec Industries.
