This is an introduction to construction methods that ensure water tightness while considering ground deformation due to seismic activity!
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.

basic information
[Range of Deformation at the Joint] ■ Allowable axial displacement: Same amount as the joint width (5–30mm) ■ Allowable bending displacement: Same amount as the joint width (5–30mm) as the axial displacement difference ■ Allowable shear direction displacement: 10mm (200% shear strain for a 5mm gap) *For more details, please refer to the PDF document or feel free to contact us.
