Analysis on the possible causes of water leakage on the external wall of buildings;

1. There is something wrong with the thermal insulation layer of the wall, which causes rainwater to leak into the thermal insulation layer, then into the wall, and then into the indoor wall from the external wall, causing the putty on the surface of the internal wall to fall off, become moldy and peel off.

2. There are cracks in the exterior wall, and the cracks in the wall may be multiple cracks or relatively large cracks, resulting in rain water slowly infiltrating into the wall through cracks in the rainy season. With the increase of rainfall, it will flow back to the wall, causing problems such as water leakage on the wall.

3. When pouring concrete, if there are problems such as unqualified concrete quality, serious concrete segregation and bleeding, loose vibration, premature formwork removal, improper design of construction joints, etc., structural cracks will also appear on the external wall, and external wall leakage will occur under the long-term action of rainwater.
