What parts of the basement need to be waterproofed?

Basically, all parts of the basement should be waterproof, and waterproofing is very important, because the underground is relatively humid, humid, and there is no sunlight.

The waterproofing of the house in which you live in your daily life is very important, and the waterproofing of the basement should not be neglected, even more so because of the special environment in which it is located.

Leibangshi recommends that you adopt the composite treatment method of "rigidity and flexibility" to form a long-term and solid waterproof layer of "multi-material combination, multi-channel fortification, complementary advantages, and long-term effect" to avoid future troubles. The basic construction steps are as follows:

1. Smooth and clean the base surface (or make a new leveling layer) to ensure that the base surface is clean, no concave and convex, no holes, no gaps, and maintain a certain humidity;

2. Use Leibangshi GS general waterproof slurry for the first waterproof treatment, pay attention to the base surface humidity and brushing method (the brushing between the two layers is the cross brushing method), and the thickness of the waterproof layer is controlled;

3. Use Leibangshi JS flexible waterproof slurry for the second waterproof treatment, and the thickness of the waterproof layer is the same;

4. Paint the protective layer of cement mortar.

Generally, the waterproofing of the basement forms a package, and the basement below the outdoor floor is wrapped. Including basement floor bottom, basement exterior wall, basement roof.

The basement is located below the ground level and may become below the surface of the water during the rainy season. It's better to do it all.

According to the requirements of the code, all structures (bottom plates, wall panels, and roof plates) with functions below the ground must be waterproof.

For long-term areas with little rainfall, local waterproofing or non-waterproofing can be selected according to factors such as the importance of the structure, the use function, the buried depth, and the groundwater level.

The waterproofing project of the outer envelope structure of the underground lifting room is divided into concrete structure engineering and self-waterproof concrete structure. The impermeability grade of the basement foundation floor is the mix ratio of the waterproof structural concrete, which should be confirmed by the laboratory, and the impermeability grade should be higher than the design grade (.

The base waterproof layer is two layers, using membrane-coating combined with waterproof case5 thick EPDM waterproofing membrane, waterproof coating 2 thick polyurethane waterproof coating.

In addition to the impermeable concrete structure of the basement outer wall, the basement outer envelope structure is self-waterproof, and the same two waterproof layers are used to carry the liquid of the membrane-coating combined with the waterproof scheme, and the membrane is made of thick EPDM waterproof membrane, 2Waterproof coating Thick polyurethane waterproof coating. The protective layer of the waterproofing layer is a 40-thick polystyrene board.

The side wall protective layer is excavated within 1m and the 2:8 ash is layered and compacted and backfilled. Compaction factor.

When the roof of the basement is not in the main body of the superstructure, the roof should be waterproof, and the waterproof layer is also made of membrane coating combined with waterproof scheme, and the protective layer of the waterproof layer is 50 thick C20 fine stone concrete.

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.

For those who are new to renovation, it may not be very clear how to waterproof the basement. But don't worry, I will give you a brief introduction to the question of how to waterproof the basement, hoping to help friends who have this need!

1: External defense and external sticking construction.

The external defense and external sticking method, to put it bluntly, is to lay the membrane waterproof layer on the bottom plate, and wait until the construction of the enclosure structure wall is completed, and then the façade membrane is directly laid on the outer wall of the enclosure structure, and then take protective measures. The biggest advantage of this method is that the concrete of the wall will dry slowly over time, which can effectively prevent indoor moisture. But there is a caveat:

When the foundation pit adopts large excavation and sheet pile support, measures need to be taken to solve the problem of plugging leakage.

Two: external defense and internal paste construction.

The external defense and internal sticking method, to put it bluntly, is to first complete the protective wall, and then lay the membrane on the protective wall and the bottom plate cushion, and wait until the waterproof layer is all done, and then pour the concrete of the enclosure structure. The only disadvantage of this method is that the construction conditions are limited, and it is a waterproof construction method that has to be adopted.

Three: off-wall lining waterproof construction.

In addition to the above two waterproofing measures, you can also add an interior wall to the inside of the main wall to meet the construction requirements. Although the scheme is a multi-channel fortification, it helps with drainage, and the only drawbacks are the high cost, the difficulty of drying out the walls of the envelope, and the difficulty of ensuring water tightness.

What are the basement waterproofing materials.

1.Cement is a more common basement waterproof material. Because it was used earlier, it is well known by the majority of users.

It is mainly made of sodium silicate + cement mixture, and its waterproof effect is obvious, which can avoid external moisture from entering the room, so as to ensure the dryness of the basement environment. At the same time, it has corrosion resistance, so it has a long service life.

2.In addition, polyurethane can also be used in basements and is very malleable, so it is easy to apply. In addition, it is extremely strong and does not break easily after long-term use.

Summary: After reading the above introduction, I believe you have a further understanding of how to waterproof the basement. If you need to know more about it, please continue to ******, and more exciting content will be presented to you in the future.

The basement is characterized by dampness, usually not suitable for living, storage should also pay special attention to moisture-proof and waterproof, coupled with waterproof engineering has always been a big problem in the construction, there are many buildings because of waterproofing is not done, often there will be water seepage, water leakage, etc., which has brought a lot of inconvenience to people. So, what materials are used for basement waterproofing? Next, let's find out with me!

1. The waterproof layer of the basement exterior wall must be protected by soft, and the brick wall cannot be built for waterproofing, which has been confirmed by countless lessons. However, the project of building walls for protection still exists, and when the backfill is excavated and observed, the waterproof layer will be punctured by the brick wall and water will enter. The materials for basement waterproofing must be rigid-flex, so that they can achieve fully enclosed waterproofing and effectively block the passage of water seepage.

2. After the water-emulsion waterproof coating is painted, the water can evaporate to form a film to achieve the purpose of waterproofing. This kind of waterproof coating is effective for waterproofing kitchens, bathrooms, roofs and other parts, but it is not suitable because the underground project is soaked in water for a long time. Because the waterproof membrane will be reduced to paint under long-term immersion in water, it loses its ability to resist leakage.

3. Basement waterproof materials can be made of waterproof coatings, waterproof membranes, this depends on your demand, large area of basement waterproofing can choose waterproof membranes, local waterproof materials can choose waterproof coatings, but now there are many waterproof materials on the market, ** is also uneven, in some brands, such as Oriental Yuhong, Zhuobao, Degao, Keshun, Qinglong, etc., Qinglong's waterproof materials are slightly more favorable.
