Seismic reinforcement method "JSPAC Method" *Seismic diagnosis currently accepting & case studies available
Heavy machinery not required. Construction is allowed while residing! Minimizing impact on appearance, lighting, and floor area.
The "JSPAC method" is a seismic reinforcement technique that enhances strength by installing axial reinforcement bars and steel plates around existing columns, and wrapping fiber sheets and filling with grout material. Since it does not require the addition of new walls or columns, tenants do not need to vacate during construction, significantly reducing total costs such as relocation expenses and preparation costs for alternative facilities. Reinforcement can be carried out while minimizing impacts on aesthetics, lighting, and floor area. ★ We are currently accepting seismic assessments. Please feel free to contact us. 【Features】 ■ Indoor use can continue even during construction ■ Utilization of existing columns eliminates the need for new walls or columns ■ Compatible with concrete columns as well as steel structures ■ Can be constructed without large machinery, reducing noise *Case studies can be viewed via "PDF Download."
