Has a proven track record of earthquake resistance and contributes to disaster reduction! Simultaneous corrosion protection and structural reinforcement are possible.
The "Reinforcement Method" involves applying a crystal lining material, then attaching carbon fiber or glass cloth (reinforcement fiber sheet), and finishing by applying the crystal lining material again on top. By combining with carbon fiber or glass cloth, it enables corrosion protection while simultaneously providing structural reinforcement (such as crack confinement effects for unreinforced structures, structural reinforcement for rusted rebar areas, and seismic reinforcement). The "Manhole Joint Displacement Prevention Reinforcement" performed in combination with carbon fiber has a proven track record of earthquake resistance, contributing to disaster reduction while achieving cost savings. 【Features】 ■ Corrosion protection ■ Crack confinement effects for unreinforced structures ■ Structural reinforcement for rusted rebar areas ■ Seismic reinforcement ■ Resistance to lateral shaking due to the use of bidirectional carbon fiber *For more details, please refer to the PDF document or feel free to contact us.
