Water seeps around aluminum alloy or plastic steel windows, leaving gaps when installing windows. Because the backfill is not clean, it will form a water cavity, so the gap between doors and windows should be filled up.

The quality of glass glue for windows is not high, and rain may seep into the cracks through the glass, so it is necessary to replace the glass glue.

Now many houses are ordinary concrete perforated bricks. After several years, the external wall may crack and leak. If it is because of cracks in the external wall, it is necessary to repair the cracks in the external wall by grouting to prevent the external wall from leaking.

This waterproof agent can penetrate into the cement layer for more than one centimeter. This method can prevent the external wall from leaking well.
