Repair and reinforcement methods for waterway structures such as open channels and tunnels!
The "SR Joint Method" is a technique for repairing and reinforcing waterway structures. Since it uses adhesive fixation instead of anchor fixation, it does not damage the concrete itself. Additionally, due to its excellent flexibility, it can accommodate significant movements. 【Features】 ■ Does not damage the concrete itself due to adhesive fixation ■ Excellent flexibility ■ Accommodates significant movements ■ Joint movements can adapt to shear direction joints ■ Superior weather resistance, water resistance, and chemical resistance, etc. *For more details, please download the PDF or contact us.
