Construction while living in the house is possible! A new seismic reinforcement method for residential foundations that can be adapted even in narrow spaces has arrived!
In conventional residential foundation reinforcement methods, long curing periods were often required due to construction circumstances 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 specialized mortar at a minimum thickness of 15mm," making it possible to work even on small sites without the need to relocate outdoor units, piping, gutters, etc., or remove flooring materials. Additionally, it is possible to complete the work in an unprecedented short time of as little as 3 days. 【Necessary Qualifications for Design and Construction】 ■ Designers - First-class/Second-class/Wooden Architect - Participants of the seminar "Seismic Diagnosis and Reinforcement Methods for Wooden Houses" (organized by the Japan Architectural Disaster Prevention Association, etc.) - Participants of technical seminars organized by our company ■ Contractors and Construction Managers - Participants of technical seminars organized by our company *The technical seminars organized by our company are conducted in a format where the responsible person visits directly.
