The "B-Star Method" is a patented technique that enhances the out-of-plane bending strength and toughness of brick walls without altering their appearance by embedding high-strength, high-durability aramid rods into the joints of existing brick structures and replacing part of the joint with a reinforcing joint material. Aramid rods possess more than five times the tensile strength of ordinary steel materials, and by inserting straight rods into horizontal joints and U-shaped rods into vertical joints, the seismic resistance of the brick wall is improved. Since the construction is limited to the joint areas, it does not affect the design of the brick wall. 【Features】 ■ Uses lightweight reinforcement materials, resulting in no increase in weight after reinforcement ■ Prevents the collapse of brick walls due to aramid rods even after cracking occurs ■ Limited to joint area construction, thus not affecting the design of the brick wall ■ Implemented through responsible construction by members of the Brick Structure Seismic Reinforcement Research Association *For more details, please refer to the PDF document or feel free to contact us.

We have published a book titled "Guidelines for Investigating the Structural Safety of Historical Buildings - Focusing on Reinforced Concrete and Brick Structures," under the supervision of Professor Takayoshi Aoki from Nagoya City University. For those struggling with the preservation and regeneration of historical buildings (cultural properties): Why is it difficult to assess the structural safety of historical buildings (cultural properties)? We explore the reasons for "unexpected" situations based on previous literature and over 100 case studies. This book provides a comprehensive overview of structural investigations related to reinforced concrete and brick structures!

This method enhances the rust prevention effect of existing cross-section repair methods by applying ERP rebar rust preventive agent after the rust prevention treatment of rebar corrosion repair methods. The ERP rebar rust preventive agent forms a moisture and chloride penetration suppression layer by being impregnated into the polymer cement-based rust preventive material applied to the rebar. This suppression layer inhibits the intrusion of deterioration factors and improves the rust prevention effect, making it effective for historical buildings with insufficient cover thickness and for the repair of RC structures. This method was developed based on the experience gained from the repair work of the old Shime vertical shaft tower, for which our company was responsible for the structural work, and is suitable for the repair of cultural properties and historical buildings where changes to the external shape are difficult.
