How to waterproof the basement? How to waterproof the basement

Main body waterproofing: The main body waterproofing mainly comes from the self-waterproofing of concrete, and the main measures of concrete self-waterproofing are concrete grade rationalization, water reducing agent and expansion agent. In engineering practice, the main reasons for the failure of doping expansion agent are the selection of unqualified products, insufficient dosage and strict construction according to the construction method, especially the lack of maintenance.

Therefore, it is necessary to strengthen the awareness of this aspect and make reasonable choices. Other measures include reducing cracks in concrete and adding fibers to concrete.

External waterproofing: External waterproofing is usually flexible, which should be full-section waterproofing and side wall external defense. The main purpose is to take into account the protection of concrete from the erosion of harmful groundwater.

Take radon pollution, for example. In addition, additional external waterproofing, such as a rigid waterproof coating, can only be used on the back water. When it comes to external waterproofing, there are several other aspects that have to be taken into account, there are diaphragm walls, basement roofs, and underground reference pools.

Node waterproofing: Basement waterproof leakage repair node waterproofing involves deformation joints, construction joints, post-pouring belts, waterproof rings, and pile top waterproofing. Among the nodes of underground waterproofing design, the deformation joint is the most complex and has the highest failure rate.

Therefore, when making the design, it should be considered as much as possible to set up a sump or drainage ditch near the deformation joint, so as to prevent water seepage, and take diversion measures, which will not affect the normal use, and is also conducive to the development of remedial work such as plugging and grouting . In the construction joints, the traditional step joints, tongue joints, concave joints, convex joints and steel plate waterstops are in principle to extend the water seepage route, which is equivalent to increasing the thickness of the concrete. The principle itself is not perfect.

Whether in the decoration of the living room or in daily life, basement waterproofing is a knowledgeable topic. In home life, the common problems of basement waterproofing and moisture-proof are mostly affected by climate humidity. For example, in the south, the weather returns to the moisture, and the basement wall will have obvious damp water droplets, while the wall with poor decoration quality is easy to grow mold or yellow.

And some details of life will also cause certain concerns about the waterproof and moisture-proof basement. So, how to do a good job of basement waterproofing and plugging?

In order to meet the high standard quality requirements of the basement waterproof project, it must be all processes to ensure the quality and leave no hidden dangers. The previous process reaches the standard, and then the next process is carried out. The basement waterproofing scheme design is reasonable, the construction is up to standard, the layered acceptance, and the overall consistent construction quality can create a perfect basement waterproof system.

The technical design of the basement waterproofing scheme needs to grasp the changes and laws of groundwater in the project area, and do a good job in the self-waterproofing of the structure for the purpose. The design of reasonable impermeability index, based on the actual construction quality, to achieve a high standard of no dripping seepage in construction and no sinking in completion. The specific standards of basement waterproof design are decomposed into various processes, the quality points are clarified, and the construction unit is supervised to meet the standards.

Basement waterproof plugging construction, should start from the excavation of the foundation pit, if the foundation has leakage water, the use of anchor spray water control support method, closed section, water impregnation, to create conditions for construction.

According to the requirements of basement waterproof quality, the basement waterproof material should be strictly controlled, and the waterproof performance of the basement waterproof microcrystalline of Tongji microcrystalline is significantly better than the performance of other types of materials. The quality of basement waterproofing materials should be qualified, it is recommended to choose high-quality brands of basement waterproofing materials, and professional waterproofing materials can ensure the quality of basement waterproofing projects. After the completion of the basement waterproofing project, the closed water test should be done, after the basement waterproof construction is completed, the door and the sewer should be sealed, and the indoor water storage should be completed for 24 hours, check whether there is a leakage point, and if the leakage is found, remedial measures should be implemented in time.

The basement waterproofing layer is easy to be destroyed during renovation. If not repaired in time, leaks will occur in the future and affect the neighbourhood. Therefore, it is necessary to pay attention to the protection of the waterproof layer when decorating, and if it is accidentally damaged, it should be repaired in time to avoid leaving hidden dangers.

Basement leakage, first you need to determine what is causing your basement leak, and then deal with it according to the specific situation:

Find a professional plumber to check whether the pipe in the wall is ruptured and cause water leakage, if it is determined that it is a pipe problem, you need to replace and repair the pipe in time to solve the water leakage problem;

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.

The basement itself is relatively dark and damp, so when doing waterproofing, it is not only necessary to take into account the prevention of open water, but also water vapor can not be ignored, so the waterproof material can choose the reaction bonding waterproof material, which not only has good adhesion with the base surface, but also has puncture resistance, high strength, waterproof life can be the same life as the building, and the construction is also convenient and the difficulty is low, so the waterproof effect of the final is also better.

1. Decoration: It is recommended to use waterproof coatings for basement construction, and the coatings include IS waterproof coatings and polyurethane waterproof coatings, which have a very good waterproof effect, and can also use inorganic high-crystal composite slabs, which have waterproof, fireproof, moisture-proof, anti-corrosion and other functions. 2. Electrical furniture:

After the decoration is completed, an exhaust fan can be installed to keep the air circulation in the basement to avoid water vapor caused by air circulation, and a dehumidifier can also be installed if possible. 3. Waterproofing: Hang moisture-proof and water-absorbing materials such as desiccant in the basement and replace them regularly.

Basement waterproofing construction plan.

Scheme 1: External defense and external sticking construction.

The exterior anti-exterior waterproofing method is to lay the membrane waterproof layer on the bottom plate cushion, and after the construction of the enclosure structure wall is completed, the façade membrane (waterproof layer) is directly paved on the outer wall of the enclosure structure, and then the basement waterproof construction method of protective measures is taken.

The advantage of this basement waterproof construction scheme is that with the passage of time, the concrete of the enclosure wall will gradually dry, which can effectively prevent indoor moisture, but when the foundation pit adopts large excavation and sheet pile support, measures need to be taken to solve the problem that the horizontal support part affects the basement leakage.

Scheme 2: Exterior defense and internal paste construction.

The external defense and internal sticking method is to complete the permanent protective wall on the bottom plate cushion, and then pave the membrane (waterproof layer) on the permanent protective wall and the bottom plate cushion, and wait for the basement waterproof layer to be completed, and finally pour the concrete of the enclosure structure. This basement waterproof construction scheme is a basement leakage plugging construction method that has to be adopted because the construction environment conditions are limited and it is difficult to implement the external anti-external sticking method.

Friends who have decoration experience know that when we decorate the basement, basement waterproofing is something we must do, so how to do basement waterproofing is something that many friends want to knowThe basement is waterproofWhat to do, and what are the precautions for basement decoration, I hope it can help you.

1. What to do with basement waterproofing.

1. How to do the basement waterproof cover? First of all, the waterproofing method of external sticking is introduced, that is, the membrane waterproof layer is laid on the bottom plate cushion.

2. Then, after the construction of the enclosure structure wall is completed, the façade membrane is directly paved on the outer wall of the enclosure structure.

3. After the ground inside the basement is leveled, use EPDM waterproof membrane to pave the ground evenly, and there must be no bubbles.

4. Mix evenly with waterproofing agent and cement ash on the EPDM membrane, and then smooth it about 1 cm.

5. The ground of the basement is laid with ceramic tiles, which is our best choice, which is not only beautiful, but also can achieve the purpose of waterproof and moisture-proof.

6. The use of waterproof and moisture-proof materials such as diatom mud or wallpaper is our best choice.

2. Precautions for basement decoration.

1. Moisture-proof is the most important problem in basement decoration, so in the selection of decoration materials, we should choose materials with better moisture-proof effect, generally speaking, in the basement ground with vitrified bricks, wallpaper on the wall, gypsum board ceiling with ceiling, etc., the moisture-proof effect of these materials is particularly good.

2. Lighting is a problem that needs to be paid attention to in the basement, because the basement is underground, there is no way to light through the door and window, so it is necessary to choose a good lighting fixture, choose lamps with better brightness, and a small trick is to refract the light by arranging glass and other items, so as to increase the light in the basement.

3. The basement is usually a stuffy place, the ventilation is not ideal, when decorating, it is necessary to pay attention to the ventilation equipment, install exhaust fans, frequent ventilation, and add some vibrant green plants, which can improve the air quality of the basement.

4. Some people like to use wood when decorating, the original ecological wood texture of wood does make people feel comfortable, but it is not suitable for use in the basement, wooden cabinets, wooden floors, these things, after many years, will be corroded, blackened and deformed, so try not to use wood in the decoration layout of the basement.

What to do with basement waterproofing, what are the precautions for basement decoration, I will introduce it to you here, I hope I will understand after reading the article on the bad game, what to do with basement waterproofing.

The basement is waterproofed as follows:

1. Structural self-waterproofing: that is, using the impermeability and compactness of waterproof concrete for waterproofing, which can be used in basements, groundwater pump rooms, pools, underground passages, etc.

2. Add waterproof layer: you can add a waterproof layer on the outside of the structure to waterproof, and the commonly used waterproof layer is cement mortar, membrane, waterproof coating, etc.

3. Seepage and drainage waterproofing: use blind ditches, seepage drainage layers and other measures to eliminate nearby water sources to waterproof.

Analysis of the causes of semi-basement leakage:

1. The waterproof design grade is low.

Although the design will take into account the return of moisture in the basement, the design of the corridor or wall panels does not set up a flexible waterproof layer, and only uses a partial brick wall, resulting in stagnant water leaking into the interior through the brick wall.

2. Negligent design of building elevation.

In some architectural designs, once the heavy rainstorm causes the stagnant water to flow into the basement along the corridor or ventilation window, it is because the difference between the bottom elevation of the wall ventilation window of the semi-basement and the ground elevation of the corridor entrance and the outdoor ground elevation is small, resulting in indoor ground water, which also greatly affects the use of the semi-basement.

3. There are defects in foundation treatment.

Some construction teams are not meticulous in the early exploration work, and the construction work is also sloppy, resulting in the hidden dangers lurking in the ground are not checked, and the quality can be imagined, resulting in the follow-up soil replacement cushion or sand and gravel cushion technology is not in place.

Or the filler of the cushion has a large water content, many impurities, or is too thick and compact, etc., which will lead to cracks in the base floor due to uneven settlement, and also cause the hidden danger of basement leakage.

Handling of the ground.

If you want to ensure the construction effect of the basement waterproofing, it is necessary to clean and level the ground and remove all impurities. If there are uneven areas, they can also be trimmed. If the damaged place is damaged, it needs to be filled with mud to make the ground smoother, and the subsequent construction will be more convenient.

Apply the base coat.

Once the ground has been cleared, it's time to apply waterproof paint. This is also an important part of doing a good job of basement waterproofing. Try to choose a better waterproof coating, and the use effect is also very good. When brushing the waterproof coating, it can be divided into two times to ensure the construction effect.
