The "FORCA PL-CF Method" is a technique for restoring the load-bearing capacity of steel members that have experienced rust progression and a reduction in thickness. By applying a low-elasticity, high-ductility putty material between the steel member and the carbon fiber sheet, the system is designed so that the carbon fiber sheet does not delaminate even when the steel member deforms. This method allows for the application of carbon fiber sheets and strand sheets even on members subjected to compressive and shear forces. 【Features】 ■ Lightweight materials ■ No large tools required for construction ■ Corrosion-resistant ■ Can be processed on-site ■ Does not damage the member *For more details, please refer to the PDF document or feel free to contact us.

The "Strand Sheet Method" is a repair and reinforcement technique that processes FRP strands, which are impregnated and cured with resin, into sheet form and adheres them to the surfaces of concrete and steel structures using a specialized adhesive. The specialized adhesive also serves as a primer and leveling material. Since resin impregnation and degassing work are not required, sheets can be applied immediately after surface preparation, resulting in reduced construction time and lower costs. Strand sheets are available in a high-elasticity type with a lineup up to 900g/m2, providing greater reinforcement effects with a single layer compared to the toe sheet method. 【Features】 ■ Short construction time and low cost ■ Significant reinforcement effect ■ Simple and high quality ■ Good construction environment ■ The specialized adhesive is grease-like, preventing resin splatter and other issues *For more details, please refer to the PDF materials or feel free to contact us.

The Outplate method is a reinforcement technique that involves tensioning prefabricated CFRP plates (outplates) with anchoring bodies at both ends, fixing and bonding them to existing concrete structures. Compared to conventional continuous fiber sheet bonding methods, tensioning the outplates allows for the introduction of prestress into the concrete, enabling significant reinforcement effects with a smaller amount of reinforcement material. Since thin CFRP plates are used as tensioning materials, there is almost no change in the external appearance or cross-section after reinforcement, making it particularly suitable for the construction of RC and PC hollow slab bridges, and it can also be applied to external cable reinforcement of steel bridges. 【Features】 ■ High bending reinforcement effect and crack control effect ■ Recovery of deflection ■ Improved durability ■ Minimal maintenance ■ Reinforcement over the supports of continuous girders can be done from the underside ■ Excellent aesthetic quality *For more details, please refer to the PDF document or feel free to contact us.

The "SR-CF Method" is a construction method that allows for the reinforcement of all seismic components using carbon fiber sheets. By using CF anchors in conjunction, the advantages of carbon fiber sheet reinforcement—such as workability, safety, and quietness—are maintained, while achieving high reinforcement effects for wall-mounted columns, beams with slabs, and seismic walls, similar to independent columns. The design and construction guidelines for this method are based on numerous experimental data and have received technical evaluation from the Japan Architectural Disaster Prevention Association. 【Features】 ■ Short construction period while occupied ■ Wide range of applicable targets ■ Significant reinforcement effect and high reliability ■ Easy construction ■ Wall-mounted columns can also be easily reinforced *For more details, please refer to the PDF materials or feel free to contact us.

The "FORCA Toe Anchor" differs from traditional CF anchors made on-site, as it is a factory-manufactured product, ensuring stable quality and eliminating the need to count the strands when bundling CF strands. It excels in workability, improves efficiency, and makes it easy to spread CF anchors in a fan shape. Additionally, because it is a specially processed CF strand, it is less likely to swell even when resin is impregnated. In the case of through-type construction, the drilling diameter can be smaller than conventional methods, reducing resin loss. 【Features】 ■ Stable quality due to factory manufacturing ■ Excellent workability, improved efficiency, and easy to spread CF anchors in a fan shape ■ Less likely to swell even when resin is impregnated ■ In through-type construction, the drilling diameter can be smaller than conventional methods, reducing resin loss *For more details, please refer to the PDF document or feel free to contact us.

"NOMST" is a new shield launch and arrival method using new material concrete. In conventional methods, ground improvement was necessary as protective work for the launch and arrival of the shield, and manual demolition of the pit wall at the entrance was required. However, with NOMST, new material concrete that can be cut by the cutter bit of the shield machine is used. Ground improvement through chemical injection is unnecessary or can be reduced, allowing the shield machine to launch and arrive without the dangerous manual demolition of the entrance. 【Features】 - Ground improvement for launch and arrival is unnecessary or can be reduced, enabling groundwater pollution prevention, shortening of construction periods, and cost benefits. - Safety during launch and arrival is ensured. - Dangerous work is eliminated, making safety management for workers and supervisors easier. - Construction periods can be shortened. - Automation and labor-saving for launch and arrival can resolve difficulties in securing skilled workers such as those in demolition work. *For more details, please refer to the PDF document or feel free to contact us.
