Introduction to basement waterproofing, what materials are used for basement waterproofing

Many people may not put the basement.

The construction of the construction is a serious matter, but in fact, in our lives, the first is the parking lot, and the second is that many supermarkets are built in the basement of the negative first floor. Therefore, the waterproofing project of the basement is very important. The basement is also a place where water seepage and leakage can occur, so extra attention should be paid during construction.

Basement waterproofing construction plan 1

Exterior defense and exterior sticking method construction Exterior defense exterior sticking waterproofing method, that is, laying a 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 exterior wall of the enclosure structure, and then the basement waterproof construction method of protective measures is taken. The advantage of this basement waterproofing solution is the concrete of the envelope walls over time.

It will gradually dry out, which can effectively prevent indoor moisture, but when the foundation pit is supported by large excavation and sheet piles, measures need to be taken to solve the problem of horizontal support parts affecting the basement leakage. This method is relatively common, we often use it, and it works very well.

The construction of 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 finally pour the concrete of the enclosure structure after the basement waterproof layer is completed. This basement waterproof construction scheme [2] is a basement leakage plugging construction method that has to be adopted due to the restriction of construction environmental conditions and the difficulty of implementing the external anti-external sticking method.

Basement waterproofing construction plan three

In addition to taking waterproof measures on the concrete wall of the enclosure structure and its inner surface, in order to meet the requirements of basement plugging construction, the basement waterproof construction scheme adds one off-wall type inner wall on the inner side of the main wall. Although the basement waterproof design scheme is multi-channel fortification and conducive to drainage, there are problems such as high cost, the wall of the enclosure structure is not easy to be fully dried, and it is difficult to ensure the water tightness of the concrete joints of columns and walls. This method is not very good in general, but there are some special occasions where you should choose it.

Through the above introduction, we have a general understanding of several schemes for basement waterproofing construction. From which we can see that the most common construction scheme is the waterproof method of external anti-posting, which is generally simple and suitable for the vast majority of places, followed by sleeping on the outside and anti-internal sticking and off-wall type. They are more restrictive in their applications.

In general, these three solutions cannot be said to have absolute advantages and disadvantages, and everyone should consider the specific situation of their own building before making a decision.

Due to the structure and use of the basement, the basement anti-basement must be poured together with the internal and external walls of the basement, and the external walls are self-waterproof concrete, all of which adopt the secondary vibration process. The specific construction technology and operation methods are detailed in the relevant chapters of the basement construction plan. The complexity of water.

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 together!

1. The waterproof layer of the basement outer 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.

Conclusion: The above content is about what materials are used for basement waterproofing? I hope it can help you. I believe that after passing the above content, what materials will you use for basement waterproofing? If you have more understanding, if you have any needs in the future, you can also refer to it.

Basement waterproofing is very important to effectively prevent the basement from being damaged by water. Here are the general methods and steps for basement waterproofing:

Cleaning and preparation: Fibers cleans the surface of the basement from dust, debris and oil stains to ensure that the surface is dry and clean.

Dealing with cracks and crevices: Repair cracks and crevices in basement walls and floors to prevent moisture from penetrating.

Waterproof coating: Apply waterproof paint or film on the basement wall and ground to form a waterproof layer. You can choose between cement-based waterproofing coatings, polymer-modified waterproofing coatings or other specialized waterproofing coatings.

Waterproofing membrane: waterproofing membrane can be laid on the basement wall and ground, such as waterproof membrane, polymer membrane, etc.

Drainage system: Ensure that the basement has a good drainage system, and the tung stove cavity includes the installation of drainage pipes and drainage outlets in order to remove groundwater and stagnant water in a timely manner.

Basement waterproofing refers to the waterproofing of the basement to prevent the basement from being invaded and damaged by water. There are many ways to waterproof your basement, including:1

Exterior wall waterproofing: Paint waterproof paint or paste a waterproof membrane on the surface of the basement exterior wall to prevent groundwater infiltration. 2.

Interior wall waterproofing: Apply waterproof paint or waterproof membrane on the surface of the basement interior wall to prevent indoor moisture penetration. 3.

Ground waterproofing: Lay a waterproof layer or apply waterproof paint on the basement floor to prevent groundwater infiltration. 4.

Drainage: Install a drainage system to drain water out of the basement to prevent water build-up. 5.

Pipe waterproofing: Waterproofing the pipes in the basement to prevent pipe leakage. The importance of basement waterproofing is self-evident, it can protect the structure and equipment of the basement, prevent moisture intrusion, and avoid damage to the basement.

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.

1. Cement basement waterproof material is the most common, its application in decoration is relatively early, people are more familiar with it, it is made of sodium silicate and cement mixture, its waterproof effect is very prominent, can avoid external moisture into the basement, can ensure that the basement environment is dry, at the same time it also has corrosion resistance, so the service life will be longer.

2. Polyurethane waterproof coating can also be used in basements, which has strong ductility, so it is convenient for construction and operation, and its strength is extremely high, and it is not easy to break and other problems after long-term use, so it can be used for a long time. It is worth mentioning that there are no joints during the construction of this waterproof coating, so moisture and moisture will not take advantage of the void, so it can ensure that the basement is dry.

3. PCM double-sided self-adhesive waterproof membrane, which is very suitable for basement moisture-proof use, which can completely block the basement moisture into the channel, and its construction is more convenient, generally a few hours can complete the waterproof and moisture-proof construction of the bathroom. And the base of this waterproof material is hard and not easy to be damaged, so the owner can rest assured.

4. Asphalt waterproof coating, cost-effective, can allow owners to buy the best basement waterproof material with a very low **, this product was launched earlier, and has been praised by many users in recent years, for which its quality is very guaranteed.
