Due to the dampness and darkness underground, it's quite common for basements to experience leakage. What are the main causes of basement leakage, and where do these issues typically occur?

Common Areas for Water Seepage in Basements:

Most common areas for basement leakage are found in specific locations, particularly during rainy seasons with heavy rainfall when outdoor pipes get clogged or road drainage is inadequate. These issues typically arise in the following areas:

1. At the base of the exterior walls;

2. At the wall sections on both sides of the deformation joints in the basement.

3. Sewer pipelines beneath the exterior walls of the underground passages.

4. HVAC pipes穿越the exterior wall of the underground room

5. The junction between the water drainage and the exterior wall.

6. Some walls with loose masonry.
