In this catalog, we introduce various products handled by our company. In 1925, Tanahashi Shoten was established in Hashima City, Gifu Prefecture, as a manufacturer and contractor of cement tiles. For nearly a century since our founding, we have been pioneering new fields, primarily focusing on "U-shaped prefabricated waterways" through the creation of various products. Without forgetting our origins, we will continue to take new strides toward the next stage. 【Contents (partial)】 ■ Box culverts / Large box culverts ■ Retaining walls ■ Storage ■ Waterways ■ Ditches *For more details, please refer to the PDF document or feel free to contact us.

We introduce the "Residual Formwork Block," which can accommodate a wide range of construction methods such as block-type, caisson-type, cellular block-type, and L-shaped block-type quay walls. In traditional methods like large steel formwork construction, the construction period was limited by the amount of formwork required. However, by using this product, continuous construction is possible, significantly shortening the construction period. Due to mechanized construction, underwater work can be greatly reduced, and the risk of formwork collapse accidents caused by rough seas can be improved. 【Features】 ■ Compatible with a wide range of construction methods for quay walls ■ Enables continuous construction and significantly shortens the construction period ■ Greatly reduces underwater work ■ Improves the risk of formwork collapse accidents due to rough seas *For more details, please refer to the PDF materials or feel free to contact us.
