What is the construction method of basement waterproofing? What should be paid attention to in the c

With the increasing number of high-rise buildings, basements are also more used by us, for example, the basement of residential buildings is generally used as underground parking lots and storage rooms. However, the waterproof and waterproof problem of the basement has always caused great confusion for everyone. The basement is dim for a long time, can not accept the sun, is very easy to grow mildew and smell, and it is more serious in the rainy season, it is very easy to produce water storage, which has caused a lot of inconvenience to daily life.

In order to prevent the occurrence of such a situation, we must do a good job in the basic waterproof construction of the basement.

First, the steps of basement waterproof construction.

Before the basic waterproofing construction of the basement, it should be ensured that the roadbed and its structure have already been accepted. First, check whether the bottom layer is reliable and dry, whether the surface is clean and free of polluting substances, and carry out the base treatment. Subsequently, the sizing surface must be coated with a waterproof layer, and the direction of the sizing should be flat, first vertical and then flat.

Finally, the waterproof quality is inspected and accepted, and the construction of the waterproof membrane project is gradually carried out in the next step.

2. Common problems in basement waterproof construction.

1) Because of the diversity of underground buildings, the design of the basic waterproof construction of the basement should follow the standard of "prevention as the leading, drainage as the auxiliary", and under the premise of mastering the surface water quality and soil layer, the excellent and efficient engineering construction laws and regulations should be adopted. For example, according to the specific situation, soft waterproofing or stiff waterproofing is selected, and if necessary, the implementation plan of rigid and flexible integration is implemented. All aspects are taken into account to ensure the quality of waterproofing projects.

2) In the basic waterproofing construction of the general basement, the purpose of the wall is to resist pressure or have the effect of self-waterproofing, and then use it to do waterproofing outside the waterproofing membrane. In the case of a waterproof work surface, you can choose the way of internal defense and internal sticking. In order to reasonably maintain the waterproof layer, a soft protective layer such as polystyrene insulation board can be selected.

3) During the basic waterproofing construction period of the basement, the amount of water in the ground should be reduced to the minimum design elevation at the bottom of the waterproofing project until the waterproofing project is carried out. At the same time, in the basement, when the maximum water level is higher than the surface of the land, the design should focus on the overall concrete structure to ensure the actual waterproofing effect.

1.When carrying out the construction of basement waterproofing membrane, it is necessary to check whether the material is a regular product and whether the quality is good or bad. If there is a problem, you need to contact the merchant to replace it, so as not to affect the subsequent construction, increase the difficulty of the construction, and extend the construction period.

2.When the waterproofing material is transported to the construction site, it is inspected for damage. Moreover, according to the requirements of the construction site, the materials should be sampled and retested, and as long as there are no problems, they can be put into use. So as not to bring various inconveniences to future construction.

Apply waterproof paint, at least three times, all over the wall need to be painted, we must pay attention to the flatness during construction, pay attention to the surrounding environment, the use of waterproof paint must be even.

The practice of paving the membrane on the outer surface of the basement wall is called external waterproofing or outsourcing waterproofing, and the specific method is: first wipe a 20mm thick 1 3 mortar screed layer on the outside of the outer wall, brush it with cold base oil, and then pave the membrane waterproof layer, and overlap with the membrane waterproof layer left under the basement floor layer by layer. The number of layers of waterproofing should be determined according to the distance from the maximum water level of the basement to the basement floor.

When the height difference between the two is less than or equal to 3m, three layers are used, four layers are used when 3m is 6m, five layers are used when 6m is 12m, and six layers are used when it is greater than 12m. The waterproof layer should be 300mm higher than the maximum water level, and a layer of linoleum should be pasted to the bottom of the water. A half-brick protective wall is built outside the waterproof layer, and the protective wall is filled with cement mortar between the protective wall and the waterproof layer.

When masonry protection, a layer of linoleum is dry-laid at the bottom, and a high fracture joint is set every 5m 8m along the length of the protective wall, so that the protective wall can tightly press the membrane waterproof layer under the lateral pressure of the soil. Finally, backfill 2 8 ash or slag in the area outside the protective wall.

Summary. Hello dear! The basement membrane waterproofing construction method is as follows:

1. The construction method of the waterproof layer of the underground membrane 1, clean the construction surface. 2. Use a brush to dip the cold base oil, paint the corners of the wall and other joints, and then spray a large area to require a uniform coating. 3. After the cold bottom oil is completely dry, paste the waterproof membrane with asphalt linoleum, and pay attention to the staggered seams to be controlled at more than 150 cm.

4. Lay a layer of 5 cm fine stone concrete to protect the waterproof layer. 2. What are the skills of waterproofing membrane construction 1. Before officially starting to pave waterproof membrane, the base must be cleaned first, including unevenness, cracking and other positions, which must be treated in advance. In addition, in order to ensure the viscosity of the waterproofing membrane, the moisture content of the base layer must be controlled at more than 8%.

2. There are many types of waterproofing membranes on the market, but they are all flexible materials, with a wide range of applications and relatively stable performance. However, the requirements for the construction environment are relatively high, requiring the ambient temperature to be higher than zero degrees Celsius, and the weather is sunny and the climate is dry, otherwise it is easy to have a weak pavement. 3. Different types of waterproofing membranes need to be paved with different methods, so the construction personnel must fully understand the relevant construction procedures and skills before construction.

Different types of waterproofing membranes need to be paved with different methods, so the construction personnel must fully understand the relevant construction procedures and skills before construction.

In particular, the hot melt method requires higher technical requirements because it needs to be heated and paved again and again, so as not to damage the waterproof membrane. 4. No matter what type of waterproof membrane is chosen, it must be compacted with a pressure roller to avoid the waterproof membrane. If there is already a situation of lifting the bag during the construction process, then the construction personnel must immediately remove the air bubbles, otherwise the position of the package will be prone to water leakage in the later stage.

As we all know, the basement is relatively damp, so special attention should be paid when decorating, if the waterproofing is not done well, it is likely to have a great impact on business life, and even cause property damage. So, what are the construction specifications for basement waterproofing membranes? Let's take a look.

First, the basement waterproofing membrane construction case is mainly based on prevention, supplemented by the basic principle of row, so that the waterproofing is more reliable, economical and reasonable. It can be designed according to the requirements of the basement waterproof engineering fortification table.

Second, the exterior wall is mainly anti-water pressure or self-waterproofing, and the construction should be carried out in accordance with the relevant provisions of the state when doing the external waterproofing of the membrane. It is necessary to understand the underground soil quality, water quality and groundwater level, and take effective fortification during design to ensure the quality of waterproofing.

3. According to Qeeka Home experts, if the highest water level in the basement is higher than the basement ground, it is best to consider the overall reinforced concrete structure to ensure a better waterproof effect.

Fourth, according to the survey data provided by the highest water level elevation, plus for the fortification elevation, the upper part of the moisture-proof treatment, there is surface water according to the safety waterproof basement design.

6. According to the actual situation, flexible waterproofing or rigid waterproofing can be used, and under special requirements, multi-channel fortification schemes such as overhead and sandwich walls can be used.

7. When the outdoor waterproof working surface of the basement is extended, the external anti-internal sticking method can be adopted, or the construction can be converted to the external anti-external sticking method.

8. When the outdoor waterproof layer of the basement is combusted, it is recommended to take a soft protective layer, such as polystyrene board.

9. For the special parts of the basement, for example, there are deformation joints, construction joints, embedded parts and other weak links should be carefully designed and dealt with in detail as required.

Conclusion of the article: The construction specification of the basement waterproofing membrane is introduced to Zhaoye here, and I hope it will be helpful to you. In the basement waterproof construction, try to install the construction specifications to deal with it, in order to achieve a better waterproof effect.

Do the math how much it will cost you to renovate your home

When it comes to the interior decoration of the basement, many people understand that it is particularly wet and cold, and the basement must be waterproof when decorating, otherwise, for people's lives, it is very likely to lead to greater impact, and even continue to lead to property damage.

1. Preliminary preparation, pre-construction solution drawing review, master the structure and technical specifications of the waterproof details on the basement engineering construction drawings, and prepare the basement waterproof engineering construction plan or technical measures. The construction of basement waterproof project should be carried out according to the acceptance of each process, and the next process construction can be carried out only after reaching the standard. The waterproof material used should have a product certificate of conformity, and the material needs to meet the design points.

When the waterproof material enters the site, it should be in accordance with the provisions for on-site sampling and re-examination, and it can only be used after the test reaches the standard. The basement waterproofing project must be carried out by the waterproof sports team. It is highly recommended to use this method of construction to follow the current relevant safety, fire prevention and environmental protection regulations of our country.

Second, the operating conditions of the base 15 20mm thick 1:3 mixed mortar screed should have sufficient compressive strength. The leveling layer should be scraped and smoothed, firm, firm, and sandless, and there should be no convex and concave, loose, bagging, gaps, surfaces, etc.

The flatness is checked with a 2m long ruler, and the gap between the leveling layer and the scale ruler cannot exceed 5mm. The surface of the leveling layer must be clean and dry, and its water content shall not exceed 9. At the junction of the bottom plate screed layer and the vertical wall, the sunny angle line at the junction of the screed layer and the puddle and the dents should be made into an arc.

The inclination of the screed layer should meet the requirements of the design plan and relevant regulations, and no partial water accumulation.

<>1. When carrying out the construction of basement waterproofing membrane, it is necessary to check whether the material is a reliable commodity and whether the quality is good or bad. If there is a problem, you need to contact the business to dismantle and replace it, so as to prevent the subsequent construction from being affected, improve the difficulty coefficient of the construction, and increase the construction period.

2. When the waterproof material is transported to the construction site, it is necessary to check whether it is damaged. And according to the requirements of the construction site, the materials should be sampled, and the work of the postgraduate examination and re-examination should be carried out, and it can be delivered without problems. In order to prevent all kinds of inconvenience for future construction.

3. For basement waterproof construction, it is not simple, and there are many problems that should be paid attention to. Therefore, it is necessary to find technical and professional construction personnel who can achieve corresponding solutions for the actual situation. In addition, it should be noted that the construction staff must not only be technically professional, but also have a certificate of induction to ensure the quality of construction in the middle and later stages.

4. In the process of carrying out the construction of the bottom plate and the wall, it is necessary to do a good job in the construction of the drainage pipeline, and only in the case of no water accumulation in the pit can the normal progress of the construction be ensured. In addition, when the wall is done with wall work, it is necessary to assemble the water-stop sheet on the screw rod to prevent inconvenience.
