The balcony is not waterproof, it turns out that there is no water leakage, and what is the matter w

It is more troublesome, if the ceiling will form a closed space between the glass roof and the ceiling, the glass roof is easy to form condensation, which cannot be avoided.

There was no leakage before the top, and it began to leak after the waterproofing, what is going on, this is caused by the error of the construction procedure:

1. Clean the base layer before doing waterproofing, and test the water storage to see if the base layer is leaking;

3. The roof waterproof layer is best to choose a tire cloth so that the waterproof effect is better (the parapet wall around the roof waterproof house should be turned up 300mm, and grooved on the women's and children's wall, and the bottom of the groove should be wiped with 45 degrees of mortar hypotenuse, and finally the waterproof layer should be pressed into the grooved end and the wall should be flattened with mortar), and the waterproof layer should be sprinkled with sand as a bonding layer on the construction surface;

4. After the roof waterproof layer is completed, the animal water acceptance test should be carried out before the protective layer is done, and the test has no leakage waterproof layer construction, and the next process can be carried out;

5. The protective layer should be C25 fine stone concrete with a thickness of 30 50mm (for slope finding), and 4@500 two-way anti-cracking steel bars should be laid, and expansion joints should be divided according to natural openings, and expansion joints should be filled with asphalt;

6. If you need to make a thermal insulation layer after the construction of the protective layer is completed, you can buy the finished product with feet and arrange it directly, or you can lay bricks, but pay attention to the thermal insulation layer should be 300 500mm away from the parapet;

7. The owner accepts and rectifies the payment handover;

The roof did not leak before, but after doing the waterproofing, it began to leak, then you look for who to do the waterproofing The technical level of the waterproof worker is really not good, it must be that the waterproofing is not done well, and the previous non-leakage place is leaked, quickly let him re-repair, or let him return the cost you have spent, and find another one for repair.

It doesn't leak before 5 o'clock, and it starts to leak after doing waterproofing, because the seam in the middle of you is not covered by waterproofing, so it is very likely that it will leak, as long as you put the sealed waterproof measures and manage them well, they will not leak.

Well, if the roof didn't leak before, and it started to leak after the waterproofing, then it must be okay, that is, he didn't do a good job of waterproofing it.

Hello, this shows that the waterproofing was done incorrectly, destroying the original normal structure, and you should find a waterproof one in this case.

The roof didn't leak before, but it started to leak after the waterproofing, what happened?

Hello, this is caused by the error of the construction procedure: 1. Clean the base layer before doing waterproofing, and test the water storage to see if the base layer is leaking; 2. If there is a water leakage, the leakage point should be repaired first, and the water storage test should be carried out after repair until the waterproof layer construction can be carried out until there is no water leakage. (You may think that the water storage test before the construction of the waterproof layer is redundant, of course, if you have a grip you can skip this process, but the consequence may be what you are now, because waterproofing, waterproofing is only for preventive purposes).

3. The roof waterproof layer is best to choose a tire cloth so that the waterproof effect is better (the parapet wall around the roof waterproof house should be turned up 300mm, and grooved on the women's and children's wall, and the bottom of the groove should be wiped with 45 degrees of mortar hypotenuse, and finally the waterproof layer should be pressed into the grooved end and the wall should be flattened with mortar), and the waterproof layer should be sprinkled with sand as a bonding layer on the construction surface; 4. After the roof waterproof layer is completed, the animal water acceptance test should be carried out before the protective layer is done, and the test has no leakage waterproof layer construction, and the next process can be carried out; 5. The protective layer should be C25 fine stone concrete with a thickness of 30 50mm (for slope finding), and 4@500 two-way anti-cracking steel bars should be laid in advance, and expansion joints should be divided according to natural openings, and expansion joints should be filled with asphalt; 6. After the construction of the protective layer is completed, if you need to make a thermal insulation layer, you can buy the finished product with feet and arrange it directly, or you can lay bricks, but pay attention to the hail bend thermal insulation layer should be 300 500mm away from the parapet wall;

I believe that many people have encountered such a problem: there is dampness near the roof lamp port in the living room or bedroom, and there is also dripping in serious cases. After shoveling, it is found that the lighting circuit is full of water, which causes serious safety hazards, and is likely to be connected to electricity, which can burn the lamps and lanterns at least and hurt people at worst.

In view of the leakage, we need to cut off the power supply, remove the ceiling finishing layer, and then judge the following aspects: whether there is dripping around; Whether the hole is drilled too deep during the decoration construction, and the threading water pipe or the floor heating pipeline upstairs is drilled; Whether there is water storage inside the line pipe, etc.

According to the on-site situation, first determine whether it is the top floor, the existing waterproof treatment of the roof, if the membrane is exposed, it is easy to age and damage due to long-term wind and sun, and the phenomenon of poor bonding occurs, so as to seep water into the lower room. If it is a roofing problem, it needs to be re-waterproofed, and the problem of water seepage has been solved.

If you are not a top-floor resident, you must understand the layout of the pipeline when you encounter such problems, because the water seepage is likely to come from the pipeline, and it may be that there is water inside the newly renovated pipeline that cannot be eliminated in time; It is also possible that the pipeline leads to the balcony, toilet and other water sources, and the water source seeps water along the pipeline to the ceiling of the household, and at the same time, the ceiling is slotted and drilled, and there is a hidden danger of cracks in the structural plate, and there will be leakage. In this case, a water or closed water test can be carried out on a water source such as a balcony, exterior wall or toilet to determine the specific leakage site and carry out the corresponding waterproofing treatment.

If the water source cannot be determined, local grouting and external waterproofing can be carried out first, and then the later situation can be observed.

Although the problem of damp water seepage in the ceiling is small, it still needs to be analyzed according to the specific situation of the site, so as to judge the water source and the cause of leakage, so as to take corresponding solutions and reasonable waterproof treatment.
