The water infiltrated or watered by the roof and parapet is concentrated at the root of parapet and gradually penetrates into the masonry at the root of parapet. There are cracks in winter, it rains in summer, and it snows in winter, which causes the roof to leak. The parapet masonry should be strengthened, and 1 ~2 layers of steel mesh should be set within the parapet flood height range to enhance its crack resistance.
