Speaking of waterproofing, my home is really very representative, it has been flooded upstairs, and it has also flooded downstairs.
Because it is an old house in the last century, cast iron pipes are particularly easy to block, so the sewer pipes in the kitchen are often anti-water.

Fortunately, there is a superb good neighbor downstairs, every time the water leaks upstairs to inform my home, and his kitchen is PVC ceiling + tile, the waterproof effect is good and does not cause great losses.

My house upstairs is also, the bathroom is too small, the washing machine is not waterproof.
Because the pipeline modification drainage is slow, the water that the washing machine can't drain down the ground flows into my house, fortunately, it was found that the "water curtain hole" did not change in time!
Some people are not so lucky, the property suffered losses, not to mention, the division of responsibility between neighbors and properties is not understood, and it may be an unfinished lawsuit.

So, today we're going to talk about these things about waterproofing.
What should I pay attention to when doing waterproofing?
Does the kitchen have to be waterproof?
Does the developer bring its own waterproofing need to be re-done?
How is the closed water test qualified?
How to remedy the leaky water in the home?
Make a few decisions before waterproofing
The decoration situation of each home is not very different, so before doing waterproofing, you must clarify a few problems.
There are several cases where the kitchen has floor drains, or the washing machine is in the kitchen, so as to be waterproof.
Because there is a floor drain, it can be discharged quickly even if it leaks.
Washing machine in the kitchen, drainage effect is not good easy to leak, just like the situation at the beginning of the article at my home, do waterproof, washing machine leakage will only spread in the kitchen, will not flow to the living room, will not affect the downstairs.

The new house kitchen has no floor drains, or open kitchen.
This kind of look at their own needs, you can not do, because the daily use of splashed water has no impact, and the water pipe burst such a large amount of running water, kitchen waterproof is not used.
Second-hand old house decoration like my home, the kitchen is recommended to do waterproof construction.
Because the sewer pipe is blocked by the anti-water situation is very frequent, waterproofing can extend the time for water to penetrate downstairs and prevent problems before they occur.

Do you want to waterproof the whole house?
Some southern friends will ask, back to the south of the day and the rainy season, the house is particularly wet, can the whole house waterproof be avoided?
Regardless of the north and south, the whole house waterproof (ground + wall) is not necessary at all.
Back to the south of the day and the rainy season, the humidity of the air is large, and the damp surface of the wall causes mold.
This has little to do with the waterproofing of the interior wall, water-resistant putty can be used, and proper ventilation and dehumidification are the most effective.
In coastal areas, it can be considered to waterproof the external wall to prevent water vapor from penetrating from the external wall, resulting in the return of moisture to the indoor wall.
"Dream Reform" has a case of transforming an island house in one phase, and the designer Dong Gong is to take the method of external wall waterproof + indoor building materials brush waterproof paint.
Small partners in the south can be used as a reference.

Speaking of the ground, do the whole house floor waterproof, the whole house is like a small "reservoir".
At this time, if you encounter a burst water pipe, it will be fine in a short time, and after a long time, the water will eventually overflow and flow downstairs through the door.
Such a small probability event is difficult to happen, and it does not work in case of waterproofing.

The installation of floor heating does not need to do waterproofing, floor heating is a pipe to go through the whole house, there is no problem of takeover in the middle, water leakage is mostly at the valve, and there are few leaks in other places.
But the bathroom installation floor heating should be secondary waterproof, which was also said in the previous article.
Should the first floor and basement be waterproof?
The first floor is selectively done, and the more humid families can make the whole house floor waterproof to prevent the ground from returning to moisture.
Basement should be done in accordance with the basement waterproof construction specifications, the specific can refer to the "Residential Design Code" and "Underground Engineering Waterproof Technical Specifications", "Underground Waterproof Engineering Quality Acceptance Specifications" and so on.
Does the developer need to do it again when it does waterproofing?
Bathroom waterproofing is recommended to be re-done.
The developer does waterproofing, the engineering materials are general, the later tile construction, it is likely to destroy the waterproof layer, so that the water leaks later, it is impossible to determine who is responsible, and the hidden project is particularly troublesome to repair.
Balcony kitchen waterproof can not be re-done.
As mentioned earlier, the kitchen and balcony waterproofing are more of a prevention, you can do a closed water test test, if there is no leakage can not be done again.
Stage summary, the following table to help you determine where you need to do waterproofing.

A few key points when doing waterproofing
Pay attention to several key points when doing waterproofing, take fewer detours, and avoid rework.
Full wall waterproofing is not necessary
The height of the waterproof layer in the shower room or the wall connected to the room shall not be less than 180cm, which is already well known to many people.
If the back of the wall is made of wood, this wall can optionally be painted with a waterproof height of 260cm.
In the bathtub area and the basin area, it is necessary to make the functional area 30cm up.
The overall height of the kitchen wall is about 30cm, and the height of the sink area is 50cm.
The balcony wall is about 30cm high.
Some companies will suggest that the owner do the waterproofing of the entire bathroom, in fact, it is not necessary, the waterproof layer will affect the firmness of the tile bonding, and it will be specially treated when laying, which is more troublesome.
The construction process should be meticulous
Before waterproofing, it is necessary to do grassroots treatment, and the walls and ground are polished and leveled.
The first waterproof, to the water supply and drainage pipe mouth, the corner of the key brush, change the pipeline under the water pipe also to do waterproof treatment.
Waterproofing at the bathroom door opening should be done on and off, and the door stone door should be installed to block the water edge to prevent water vapor from seeping into the opposite wall along the floor gap, resulting in mold on the wall.
Closed water tests must be done
Waterproofing in any location, including roofs, should be tested for closed water.
Before the closed water test, the door will be used as a water blocking measure, and the bucket will be used as a buffer when releasing water to prevent the water from flowing too fast and the impact force will damage the waterproof layer.

Good communication with downstairs neighbours in advance (no neighbours looking for property) for easy observation at any time.
Normal closed water height of 3 ~ 5cm, closed water time of 24 ~ 48h, during the timing to the downstairs to observe whether there is water leakage, if not, 48 hours after the water level does not drop, it means that the waterproof qualified.
The water blocking test is not as long as possible, the time is too short to judge whether the waterproof is qualified, and there is no risk of leakage; too long, the waterproof layer is soaked in water for a long time, and it is also affected.
Three points against seven points
The drainage system is good, even if the water leaks, there will only be a small amount of water on the ground, which will not cause too much damage.
Therefore, when laying bricks on the ground, it is necessary to find a good slope so that the water can flow quickly to the floor drain.
Also choose not easy to block, large displacement of floor drain, such as dry sealing floor drain than water sealing drainage faster, read the product manual when purchasing, you can also bring a bottle of mineral water to test it on the spot.
In this way, the ground does not accumulate water, and the possibility of seeping downstairs is much smaller.
Post-repair is far less than a one-time fix
The waterproof warranty is 5 years, and if a water leak occurs within 5 years, you can directly find the construction party to deal with it.
However, the later repair often requires planing floor tiles, demolishing walls, and making a big move, so it is better to be in place in one step, be careful in the construction stage, save worry and save money.
When doing the closed water test or before the tile is leaked, it must be reworked in time to repair or redo, a little can not be on, find the leak point, do the closed water test again after doing waterproofing.
If you find water leaking, don't blindly dismantle the wall and smash it
Water leakage that has been completed or used for a period of time is more complicated to deal with, and then enter this lie.
Indoor water leakage is checked first and repaired later
Indoor kitchen, bathroom, balcony, etc. do not panic if there is a leak.
Not necessarily leaky is the waterproof layer is broken, to use the exclusion method to check one by one, first of all, to find the leak point, go to the neighbor's house to see the location of the leak.
If the corresponding position is around the toilet, it may be that the toilet is not safe, or the flange ring is broken, at this time find a worker to remove the toilet, change a flange ring and re-install it.
The leakage point corresponds to the drainage outlet, such as the floor drain, wash basin, washing machine sewer, etc., and the water leaks when used, that is, the problem of floor drain or drain pipe.
Floor drainage can be solved by finding workers to dismantle it and reinstall it.
Sewer pipe leakage is generally the gap is not treated well, with a blade to clean up the pipe around, and then reseal the water without leaking on the line.
The above reasons are excluded, then it may really be a cracking of the waterproof layer.
At this time, the most fundamental method is to dismantle and do it again.
If it is the wall surface seepage, most of the hidden pipes in the wall leak, find a plumber to suppress the overall pipeline, if the pressure is normal, you can rule out that the water pipe leaks.
The pressure gauge shows abnormality, can not find the water leakage point, can be located with a thermal imager, fast and accurate, the general professional maintenance master has this instrument.
Find the leak point and slot it or go straight to a new water pipe.

If you have searched all your homes and have not found a leak, it may be that the neighbor's house or the public supervisor has a problem, at this time to find the property and neighbors, their own home has been unable to solve.
Outdoor leaks can only be remedied
Outdoor leak filling is different from indoor leakage filling, in addition to the terrace, floor and windows, whether it is the roof or the external wall can only be remedied, can not be dismantled and reinstalled.
Moreover, maintenance is difficult, and it is easy to leak again due to disrepair and aging waterproof materials.
Terrace waterproof, the use of membrane waterproof material, this material can avoid the destruction of ultraviolet rays, but also can resist the damage of temperature differences to the waterproof layer, so once the waterproof layer is damaged and water leakage occurs, it is necessary to remove the original waterproof layer to re-do waterproofing.
There are 3 reasons for leaking windows.
One is that the window seal is aging, the drainage hole is blocked, which is very simple, dredge the drainage hole, or replace the window seal, a treasure is very cheap, simple and easy to use.
The other is that the window is not qualified when processing, the air tightness is not good, and there is no drainage hole.
For product quality problems, you can only choose regular manufacturers to avoid when purchasing.
The third reason is that when the window is installed, it should be glued and waterproof, and if it is not done well, there will be water leakage in the future.
For such problems, it is recommended that during installation, workers are instructed to carefully glue and not be sloppy.
You can also add a layer of polypropylene tarpaulin when decorating, which is better than the waterproof effect of simple glass glue.
In this way, the water leakage is remedied, and the internal correction of the door and window frames is done first, and the internal waterproof is made with anti-mildew glass glue.
If it is the external wall of the window that seeps water, the water leakage of the window wall of the new residential area is the responsibility of the developer, and it is possible to find them to repair it.
Not to do waterproof sub-new or old residential areas, after the warranty period, you need to find a qualified construction team to re-waterproof the external wall, if the indoor wall has been moldy, you also need to remove the wall skin for waterproofing.
Roof waterproofing has always been a major problem for families living on the top floor, and the leakage is made up, and the leakage is made up.
After the warranty period, the developer does not care, and some properties are not responsible for maintenance.
There is no way for the owner to pay for the roof on his own head to do a good job of waterproofing, but the roof leakage of other people's homes will still seep through.
Therefore, it is best to do the whole building together for waterproofing and leak repairing on the top floor, but because of the high cost, the property is not affordable, and it is difficult to reach an agreement with multiple residents to take money together.
Roof leak repair is roughly to find the leak point, judge whether it is local maintenance or re-do waterproofing, the specific operation is not a sentence or two sentences can be explained clearly, we have the need to be a separate article, here is not detailed.
Selection and price reference of waterproof materials
Construction waterproofing is a more technical test of work, so like me, the little whites, or ask the professional construction team to help deal with it.
We just need to have a general understanding of waterproofing materials and their uses to prevent them from being fooled by unscrupulous businesses.
In order to facilitate preservation and comparison, I put several waterproof materials together and made a table, you can collect and save Oh~
There are various names of various waterproof materials on the market, but they are inseparable from these basic materials, and when they are not clear, they ask the merchants about the composition of waterproof materials.
wary! Punch glue scam
There is a leaky place at home, do not rush to the hospital, those treasures, a city or vehicles wandering around on the street, written "professional leak prevention" are deceptive.
If you find them, they will tell you that without smashing tiles, professional punching holes to inject glue waterproofing, and then punch two holes in your home tiles, you can inject dozens of pounds or even hundreds of pounds of glue, the price of glue is more than 100 yuan a pound, a scam down to be cheated of thousands of yuan or even tens of thousands of yuan.
It has no effect at all, not to mention, the money is enough to dismantle and reinstall.
In case you are accidentally deceived, you should call the police immediately, and you may be able to recover some of the losses.
