Who should deal with the leakage of the external wall of the house?

You can find a property to deal with the leakage of the external wall of the house.

When there is water seepage in the external wall, waterproof construction is needed again. It can be treated with organic polymer waterproof material, and the waterproof agent can be sprayed evenly on the wall with a sprayer. This treatment method is not only effective, but also low cost. You can also use the method of first opening and then grouting to treat the leakage part locally.

If the house is still under warranty and the external wall of the house leaks, the developer should be responsible for the maintenance. However, if the house leaks, it is no longer within the warranty period, and the water seepage is not man-made, the property can be responsible for the external wall leakage, and the maintenance cost can be deducted from the public maintenance fund.

Precautionary measures for water seepage on external walls of houses are as follows:

1. Water seepage on the external wall of the house may be caused by scaffolding blockage. In this case, it is necessary to clean up the sundries in the scaffold, and then build half a brick with cement mortar of 1 2 in the scaffold eye to ensure the mortar joint is full and tamp it with a thin steel plate. C30 fine stone concrete shall be filled on the outside of the scaffold eye. After the wall is dry, one or two layers of cement mortar should be smoothed and calendered.

2. When the horizontal mortar joint of hollow brick is treated, the fullness should exceed 80%. If it is vertical mortar joint, it should be filled with mortar, and there can be no false joint and transparent joint. Moreover, when building hollow bricks, the brick glue should be wetted first, so that the dry bricks can't get on the wall.
