クリテック工業 Company Profile

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.
