Construction while living in the house is possible! A new seismic reinforcement method for residential foundations that can be applied even in small spaces has arrived!
In conventional residential foundation reinforcement methods, long curing periods were often required due to construction convenience and the need to secure working space, making it difficult to carry out work while living in the home. The "FRP Grid Foundation Reinforcement Method" achieves both construction in narrow spaces and while living in the home. The method involves "chipping away the decorative mortar of the existing foundation" → "fixing an FRP lattice to the existing concrete with anchor pins" → "applying a special mortar at a minimum thickness of 15mm," making it possible to carry out construction even on small sites without the need to relocate outdoor units, piping, gutters, etc., or to remove flooring materials. Additionally, it is possible to complete the construction in an unprecedented short time of as little as 3 days. 【Necessary Qualifications for Design and Construction】 ■ Designer - First-class/Second-class/Wooden Architect - Participants of the "Seismic Diagnosis and Reinforcement Methods for Wooden Houses" seminar (organized by the Japan Architectural Disaster Prevention Association, etc.) - Participants of the technical seminar organized by our company ■ Constructor/Construction Manager - Participants of the technical seminar organized by our company *The technical seminar organized by our company is conducted in a format where the responsible person visits directly.
