Shortening the construction period compared to conventional methods! Achieving seismic reinforcement while staying in place.
The "AP Method" is a seismic reinforcement technique that uses completely premixed mortar applied through wet spraying. It allows for the production of the required amount simply by adding water and mixing on-site, making it easy to manage the mix. There is no "water leakage" due to formwork bursting, and it features crack control. Designs can be based on the same seismic diagnosis standards and renovation design guidelines as conventional concrete (RC), and it has received technical evaluation from the Japan Building Disaster Prevention Association. 【Features】 ■ Can be applied in narrow spaces where conventional concrete pouring is difficult ■ Construction can be completed in about 1/2 to 2/3 of the time compared to conventional concrete pouring ■ Reduces the amount of mixing water from the conventional 40% to 14.5%, a 65% reduction ■ Does not use wood for formwork ■ Uses a premixed material with vinyl fiber to suppress the risk of crack occurrence *For more details, please download the PDF or feel free to contact us.
