What should I do if the water flows back into the balcony above the balcony of the old building on a

Due to the fact that there are many aluminum alloy windows for balconies, there are two main reasons for rain and water ingress:

1.The balcony wall is relatively thin, and the aluminum alloy window is often "sitting" on such a wall, and the window and the wall lack the necessary sealing. When it rains, water seeps in through the gap between the window and the wall.

2.When it rains heavily, the lower part of the aluminum window will spill the rainwater from the outside into the room.

The approach to the above two problems is as follows:

1.The joints between the outside of the aluminum alloy window and the wall are completely sealed with cement, and it is best to use the exterior wall tiles to paste it diagonally.

2.Make waterproof glue on the inside of the balcony and then also paste it with exterior wall tiles (very beautiful).

3.The kind where you make a drain on the balcony and drain it directly to the outside.

4.Metal strips are used at the entrances of the living room floor and balcony to prevent stagnant water from being directly absorbed by the floor.

5.If necessary, modify the aluminum alloy window and transform it into an open sealed type (but it will be inconvenient to dry, and there are also problems with ventilation, such as installing a screen window).

The waterproof project is a "fine work", grasping the key to leakage, selecting the right materials, and passing the construction technology. The key to leakage prevention refers to the various nozzles, that is, nodes, that penetrate the wall and the ground. For example, floor drains, hot and cold water nozzles, sewer outlets, etc., the junction between them and the ground and the wall, if not well sealed, it is easy to cause leakage.

During construction, the junction should first be coated with waterproof coating, and then the flat surface should be treated. In addition, the area where the wall meets the ground is also the focus of waterproofing.

When the storm comes, the first waterproof gate is the balcony doors and windows. The quality and sealing of doors and windows should be good, and the inside and outside direction of the waterproof frame should not be mistaken. The second waterproofing level refers to the waterproofing of the balcony floor.

The first thing to do is to ensure that the ground has a slope. The lower side is the drain; Also, make sure that there is at least a height difference of 2 3 cm between the balcony and the living room. To make the living room and the balcony have such a height difference There is a certain degree of difficulty, you can use a marble slab to decorate, and use cement to fill the leakage spirit at both ends of the stone slab and below to do a good job of plugging the joints and preventing leakage, which is both practical and beautiful.

The third waterproof barrier is to keep the balcony floor drain unobstructed. On heavy rainy days, when the rainfall is greater than the drainage capacity of the floor drain, it is possible to form water on the balcony floor, and when the amount of water is too large, it is possible to overflow the waterproof frame of the sliding door and enter the room. Although it is unlikely, it does happen occasionally, so it has to be prevented.
