The roof is filled with pearl salt. How to solve the leakage after the waterproof has been done?

First of all, check the waterproof problem, check the leakage, it is really not possible to lay a layer of waterproofing to try.

Check the leakage point to see if the local area can be treated, otherwise the waterproof area will be expanded. You can also try a new type of waterproof coating, and you can consult the building materials store.

If the waterproofing is not done well, it will not leak if it is not covered with tiles.

Is it connected with other houses, other people's houses are high, and there is a little ramp on this side of the house, so the rainwater seeps in and stays over.

Causes

1. The problem of materials, waterproof coatings must be selected with high quality, do not choose inferior materials, the waterproof effect of inferior materials is really too pitiful, generally after a cycle, there is no waterproof effect.

2. The problem of the construction of the workers, the workers may be in a hurry to do the roughness, the rejection of the membrane is not dealt with well, and the uneven brushing is also the reason for the poor waterproof effect.

3. The problem of household pipes, the interface of the pipeline is also a very important place, and the water leakage may be in the pipe interface and the yin and yang angles, that is to say, the waterproofing of these points is not in place and has not been dealt with well. Therefore, the position of this node must be dealt with well, waterproofed with mortar, and then waterproofed after coating, so as to ensure that this will not happen.

Waterproof application

1. The waterproofing of the project mainly refers to the water that can be seen in the open water. A small amount is made to protect the building from water vapor and moisture erosion. The main materials in this area are coils, polyurethane and so on. The construction requirements are high and the process is complex.

Second, the waterproofing of home decoration refers to the waterproof common sense, waterproof materials and waterproof technology related to family life. Including but not limited to waterproof and moisture-proof treatment of roofs, toilets, balconies, exterior walls, kitchens, basements, swimming pools and other locations. This subdivision is taking shape, the construction requirements are relatively low, popular, and practical.

Water leakage in China's buildings is widespread, especially the roof leakage is more serious, according to statistics, it has reached 95%, the root cause is that the national water quality protection period is only 5 years, resulting in the average level of waterproof materials in the market is not high, and developers have no motivation to use good materials.

Why does it leak and why does it leak after repeated repairs?

Now the building is basically a reinforced concrete structure, concrete is a rigid material, natural cracks, so must be through the attached waterproof layer to solve the problem of leakage, only by the concrete additives, is not able to fundamentally solve the problem, this is why one of the waterproof principles is the combination of rigidity and softness, "rigid" refers to the quality of concrete, which is fundamental, "soft" refers to the additional waterproof layer, used to fight cracks.

Understanding this principle, it is not difficult to know that if rigid waterproof materials are used to control water leakage, it is difficult to achieve good results. The reason for repeated leaks after repeated maintenance lies in the inappropriate waterproof materials selected.

At present, the cement-based waterproof coatings such as JS waterproof coatings commonly used on the market are rigid waterproof coatings, which can not resist the cracks of the base layer, and the waterproof layer itself will crack, and some customers have done it 6 times and leaked, which is the reason.

Due to the existence of such a deficiency in rigid waterproof coatings, it is called flexible waterproof coatings by adding elastic additives to improve crack resistance, which is called flexible waterproof coatings.

Therefore, from the perspective of crack control, only elastic waterproof materials can be selected. At this point, it is necessary to consider other aspects.

Due to the various waterproofing membranes, there are major hidden dangers in bonding with the base layer, lap joint treatment itself, and strengthening the treatment of details, so although it can play a good waterproof role in theory, it cannot be done in practice, therefore, the use of waterproof membranes should be avoided as much as possible for household waterproofing.

Until now, all that was left was the elastic waterproof coating. If you want to leak water, what else do you need to consider?

First of all, the aging resistance, the actual life under the actual use conditions, not the laboratory life, many elastic coatings such as polyurethane waterproof coatings can not be immersed in water for a long time, can not be exposed to use, can not be corrosion-resistant, these in practical application caused by the life is greatly shortened, resulting in repeated leakage. There is also the physical strength of the coating, some elastic waterproof coatings have weak physical strength, too delicate, and easy to break, so only the physical strength is high, and the leather is durable. There is also the bonding performance with the base layer, no matter how good the material, it will be in vain to fall off, and some materials have good performance in all aspects, but it is a pity that it is poor.

Finally, the construction should be simple, no professional technology is required, and anyone can dry the waterproof material to form a reliable waterproof system. To sum up, it is currently recommended to use one-component high-strength environmentally friendly urea-based waterproof coatings, which can be guaranteed for 50 years and relieve the trouble of repeated water leakage.

It's best to make a top or plant grass and flowers.

We all know that the kitchen and bathroom are the places with the largest moisture in the home, especially the sanitation 1, check and accept the appearance, variety, specification, packaging, size and quantity of materials, and form the corresponding acceptance records.

2. Check the quality certification documents of the materials and include them in the engineering and technical files.

3. After the material enters the site, the material inspection report shall be issued according to the specification.

4. When all the indicators of the physical properties of the material meet the standards, it is qualified; If an index does not meet the requirements of the standard, the index should be re-sampled in the tested product for re-inspection, and the re-test result meets the requirements of the standard, and the batch of materials will be judged to be qualified.

5. Waterproof material. There are three main categories: waterproofing membranes; 911 polyurethane waterproofing material; New polymer cementitious waterproofing material.

The last category is divided into general-purpose GS waterproof materials and flexible JS waterproof materials. Among them, the universal waterproof material is suitable for the waterproofing of the indoor floor and wall of the family.

1. There are two main reasons for leakage in the bathroom.

Causes: 1. There is a BAI leakage point in the waterway.

2. The top layer of waterproofing is unqualified. You can ask the master to check whether the sewer pipes of his own dao are not tightly closed, focusing on checking the water pipes of the basin and toilet, and the workers may damage these two places if they are not careful during the decoration.

2. Test whether the water inlet pipe is leaking.

1. If it keeps dripping, turn off the main gate first, and open all the faucets at home to drain all the water in the water pipe, and then turn off the faucet. (Note: Do not use any water for half a day or a full day after two or three hours.)

2. After confirming that the dripping water downstairs has stopped, open the main gate again, and do not use any water for half a day or a whole day after two or three hours.

3. If there is a drop of water downstairs, it means that the inlet pipe is leaking, and if it is not dripping for more than a day, it means that it should not be a leak in the inlet pipe.

3. Test whether the drain pipe is leaking.

Find a soft water pipe connected to the faucet at one end, and flush the water at the other end against the floor drain, and insist on more than half an hour to see if there will be water leakage downstairs. At this time, do not let any water flow outside the floor drain so that you can accurately test whether there is a leaking drain problem.

Fourth, the solution.

1.If it is a leaking water pipe, there is no good solution but to dig it up.

2.If it is only the waterproof layer of the bathroom or the surface leakage, there is no need to dig it up, as long as the surface of the bathroom is treated to a drip.

The cause is still coming.

It is caused by the source of construction irregularities.

If the BAI does not standardize the closed water test and inspection, it will eventually lead to water leakage. dao

The national standard for closed water test requires that it needs to be done twice, once after the waterproof coating is completed and the waterproof coating film is dry; The second is after the waterproof protective underlayment or finishing layer has been completed.

If only the first closed water test is done, then the waterproofing may be damaged in the subsequent process of making protective cushion or laying wall and floor tiles.

There will be waterproof dead corners around the toilet drain and floor drain, and it is possible to seep down the water pipe. Then there is the possibility that the waterproof layer is accidentally damaged when tiling. After you finish pasting the floor tiles, you can apply a layer of plugging spirit on the brick joints.

No, it's still not waterproof.

Causes of leakage in the waterproof layer of the bathroom.

The bathroom leaks, and most people's first reaction is that the waterproof is not done well, but there is one link that is easy to be overlooked, that is, the bathroom backfill material. Now there are several backfill methods on the market, including slag backfill, cinder backfill, ceramsite backfill, and prefabricated slab overhead. These backfill methods are relatively heavy, and excessive load will cause the main body to settle, crack, and lead to water leakage.

Long-term humidity is also a breeding ground for bacteria, and it is also easy to collapse and easily become a parasitic place for cockroaches.

The drawbacks caused by the traditional backfill method have plagued everyone for many years, especially the waterproof problem, and I have been worried about how to solve it! After years of market research and development, we have launched a new material for backfilling in the bathroom without stagnant water - Wei Bao, which has seized most of the market share once it has been launched. Guardian has the following characteristics:

1: Waterproof, this product is divided into two components A and B by high-tech products, and uses special equipment and cement foaming. He will make the cement produce countless independent small pores, which are not connected to each other, have strong adhesion to the wall, and have good water blocking performance.

Screeding and a second waterproofing are omitted.

2: Integrity, on-site overall pouring construction, closely combined with the main project, the bottom of the caisson does not need to do secondary drainage holes, which solves the problem that the secondary drainage holes are easy to block.

Three: lightweight: after the completion of this product, the dry density is only 300-350kg m once molding, no need to do plastering leveling layer, can be directly paved tiles.

Four: environmental protection: the required raw materials are cement, cement-based fillers, this product is neutral, does not contain benzene, formaldehyde and other harmful substances, to avoid environmental pollution.

5. Liquidity; Before forming, it has super fluidity, solves the various dead corners that cannot be reached by the construction of the waterproof layer of the toilet caisson, and covers the water supply and drainage pipe as a whole to prolong the service life of the water pipe.

Six: durability, the same as the life of the main project.

Seven: compressive resistance: overall pouring, inside and outside, no shrinkage, no sinking, compressive strength above the national standard.

Eight: the construction is simple, all can be completed within 1-2 hours, the site is clean and tidy, and the maintenance is convenient in the future.

Water seepage, dampness, peeling and other conditions at the bottom of the bathroom wall are generally caused by water leakage in the bathroom. The most important thing now is to find the cause of the water leak:

1. Find a professional hydropower worker to check whether the pipeline is ruptured and causes water leakage, etc., if it is a pipeline problem, it is necessary to repair the pipeline in time to solve the water leakage problem;

2. If there is no problem with the pipeline, then consider that the waterproof layer is not done well and cause water leakage, if the local water leakage is serious, it is recommended to do the waterproofing again, so as to fundamentally solve the problem.

More than 80% of the water leakage in the bathroom is concentrated in the yin and yang corners, pipes, sanitary ware, floor drains and other places, so it is recommended to use kitchen and bathroom waterproof slurry when doing waterproofing, first repair and strengthen these permeable parts, and then do waterproofing as a whole, so that the waterproof effect is better. However, remember to carry out standard construction according to the requirements during construction, so as to ensure a good waterproof effect.

Looking for a store specializing in waterproofing, there is generally a job to undertake the leakage, find a professional to see the scene to know how to deal with the better, I am to fill the leakage, if it is a leak around the drainage pipe, it can be handled downstairs, you can also not knock on the tile, there are many ways to fill the leakage, you need to see the scene, there are professional materials to fill the tile joint, the tile is not leaky is the tile gap leakage, water under the tile, as long as the tile joint can be filled with professional materials, It's just that the water under the tiles needs to evaporate naturally for a long time, and the cracks below are more quickly effective, and the leakage is generally relatively high, and there are not many professional leaks, and the money is not high, and I basically repair it free of charge within 5 years after I talk about it, don't look for those who drive on the street, they don't have a shop that basically does not repair.

You can also knock on the bathroom tiles and repaint the waterproofing, which is more expensive and time-consuming. Now the leak repair should be available everywhere, basically the store that specializes in waterproofing to ask.

This problem is often encountered, the frequent leakage part is the position of the gutter and the rain drain pipe handover, first ensure the smooth flow of water, do a good job of sealing the joints, seal with weatherproof adhesive or membrane waterproof, if it is still not done well, replace the leakage bucket and reinstall it to make waterproof.

First of all, it is important to note that cement cannot be added to the plugging king.

If you are sure that the leak point is the crack between the floor slab and the floor slab, the "quick-setting" plugging king construction is as follows:

1.First, use a chisel to chisel a groove 1 2 cm wide and 2 3 cm deep along the crack. Rinse the tank with water to clean the dirt.

2.Quickly stir the "quick-setting" plugging king and water in a ratio of 1:, and quickly stuff it into the trough when it feels hot, and compact.

Stir a fist-sized dough each time, because a good plugging king solidifies quickly. )3.All plugged are sprinkled with water on the plugging king.

Very important) can also use the "retarding" plugging king: stir evenly with water, and use a trowel to wipe the plugging king on the cracks. Wipe twice, 5kg bag 3 4 square.

However, no matter what kind of plugging king is a rigid waterproof, if the foundation sinks again in the future, it will crack.
