The basement and the education room that was not connected before due to the blockade of the concrete wall and soil was horizontally coupled. The reinforcement was done while being jacked up and the wall pillar was constructed and the building was reinforced by indenting stakes on areas that settled. We did not use carbon fiber or metal panel adhesion method that cannot guarantee the strength and safety. Instead, we used scientifically proven wire rope and strained with steel strands to remove the pillar and bearing wall to connect the undergrounds.
