Company information
Established in 1919, our long-standing manufacturing company, Tōtetsu Plus Co., Ltd., will start on September 1, 2024, following our spin-off. More details can be found in the "News" section of our website. Our equipment for waterway and retaining wall structures, designed to prevent floating destruction, has a history of about 50 years. (Including float valve-type weep holes, side drainers, under drainers, pad filters, TM filters, etc.) We are a comprehensive manufacturer of rainwater storage and utilization systems. We are committed not only to runoff control but also to the full utilization of rainwater. (We propose higher quality rainwater use with initial rainwater cut-off products and handle above-ground tanks and storage basins.) Backflow prevention valves for water drainage in handholes discharge water from handholes, joint utility trenches, and information boxes, preventing groundwater intrusion. The origin of the sandbag station is our company, Tōtetsu Co., Ltd. You can rely on us for all your sandbag station needs. Our sandbag stations are foldable, making them easy to move and transport. We cater to various needs, including different sizes and colors.
