The problem of Mr. Lu celebrating the new garden

Supervising and answering questions

The water leakage on the top floor of the house is a very serious problem. If it is not solved in time, it will not only bring problems to the whole house, but also seriously touch people's hearts. Especially in rainy days, the top floor leaks and needs to be repaired urgently. Like Mr. Lu's family, I also encountered the same problem. So today, let's analyze the causes of water leakage on the top floor. How to solve it?

1. Why does the top floor leak?

1, the house is old, it has lived for a long time, the maintenance measures are not done well, and the waterproof material of the roof layer of the house is aging and damaged, so the water leakage of the house is also a normal reason.

2. Many plants are planted on the top floor of some houses, which actually has a certain influence on the waterproof materials of houses.

It is not normal for builders to cut corners and use inferior waterproof materials to make the house watertight. However, with the strictness of the national construction quality supervision department, this situation is becoming less and less.

Second, how to deal with the top floor leakage?

1. Reset the waterproof layer suitable for exposure in this area. If the waterproofing material is the selected waterproofing membrane, it is suggested to adopt the national standard 3mm polyester tire aluminum film SBS, and seal the lap joint of the membrane to achieve seamless waterproofing.

2. Additional enhancements are made to the roots of water heaters, roof pipes, yin and yang angles, etc.

Whatever the reason, we must repair the water leak on the top floor. First, we must find the location of the leak. If there are cracks, cut the cement sand into a V-shape, then brush the waterproof material, and then brush a layer of cement sand, but the area is large and the thickness is high. There is also a groove on the edge of the cement sand, which will stick firmly.

4. If the water pipe leaks, there may be a problem in the installation process or the material of the water pipe. This needs to be examined in detail.

5. The roof with no water leakage point can be found. It is recommended to redo waterproofing and choose waterproof slurry. Can be painted many times, can be fortified many times. Complete waterproof layer should be brushed twice, with a total thickness of less than 2mm, and then the cement mortar protective layer should be brushed. After the protective layer is dried, conduct comprehensive waterproof coating, and then use cement mortar as the protective layer. Then brush flexible waterproof cement slurry. This can be repeated for 3-4 times, which has ensured the waterproof effect. But the base surface must be handled well, and the outermost surface must be protected with cement mortar.

Bian Xiao abstract

There are many leaks in old houses, and no waterproof material can guarantee the quality for decades, so we should pay attention to the maintenance and repair of houses. If you just buy a house for a long time and it leaks, then you have to find a property, because this is their responsibility.
