The "HSB method" is a construction technique that ensures watertightness by filling the joints of concrete components with a specialized sealing material known as "high-elastic adhesive sealing material" from the inside, taking into account ground deformation due to seismic activity and other factors. The method is applicable to typical examples such as precast concrete box culverts and large reinforced concrete flumes. Additionally, it can be applied to concrete structures where the displacement of the joints required by design falls within the deformation range specified by this method. 【Features】 ■ High-elastic adhesive sealing material ■ Watertightness against joint shapes and joint displacement ■ Joints that can withstand Level 1 and Level 2 seismic motions in sewer pipelines *For more details, please refer to the PDF materials or feel free to contact us.

The "Sokobasu (S-VS)" is a concrete secondary product that enables immediate backfilling by integrating the base plate, with vertical side wall shapes that allow for easy compaction. The 1-meter cover plate reduces the installation effort compared to U-shaped gutters to one-fourth, achieving a shortened construction period. Additionally, by providing a gentle V-shaped slope at the top, it allows for rapid rainwater collection. With its distinctive V-shaped base plate design, it possesses high flow performance, ensuring flow velocity even during light rain. 【Features】 ■ Improved workability ■ Rapid drainage and collection ■ High flow performance ■ Universal design ■ Low noise, low vibration *For more details, please download the PDF or feel free to contact us.
