How to deal with cracks in the load bearing walls of the house

Firstly, the shape and direction of the crack and whether there is a development trend are observed, the causes of the crack are analyzed, and the nature of the crack is determined. Determine whether the crack has an impact on the safety of the house structure, and if it does not affect the safety, it can be treated simply. Otherwise, professional and technical personnel should take appropriate technical means to reinforce the treatment.

If there is really no repair value, it should be demolished as soon as possible.

Causes of cracks:

1. After the completion of the house, various pipelines are buried through the wall or other behaviors that change the use of the house, which destroys the integrity of the wall, reduces the bearing area of the wall, and weakens the bearing capacity of the wall, thus causing cracks in the wall. It should be reinforced in time.

2. The crack caused by the uneven settlement of the foundation, this crack is generally an oblique crack, which develops from the bottom to the top, showing the figure of "eight", and the crack goes to the depression.

3. Thermal cracking, which is the most common in the wall, is located at the junction of different materials, and is produced due to the difference in their thermal expansion and contraction properties. This kind only affects the interior appearance of the house, does not affect the safety of the house, can be pasted on the cracks of non-woven fabrics, installed steel mesh or mortar plugging joints, and then used paint for repair.

4. The quality of masonry construction is poor, the ash is not full when the wall is built, the thickness is uneven, the assembly method does not meet the requirements, etc., when the brick wall is built, the bricks are not wet, and the dry bricks are used on the wall, etc., which will reduce the bearing capacity of the masonry, so that the wall will have cracks in the future.

There are many causes and forms of cracks in load-bearing walls, and it is recommended to invite a building structure professional to the site for investigation, and if necessary, ask the local quality supervision department to do the identification on the site, and then deal with it according to the conclusions reached.

First, look at what nature the crack is.

If it is a temperature crack, the surface layer is treated, the loose part is removed, and then 1:3 cement mortar is used to make up for the leveling, and then the surface layer construction is carried out according to the original ground practice.

If it is a structural crack, it is necessary to arrange the structural engineer of the relevant design institute to analyze and discuss, and the qualification unit will determine the long repair time.

Hello, glad to answer for you! I have received your question and will get back to you right away.

This depends on the crack in the layer above the load-bearing wall.

Ask you about the cracks in the walls where your body foundation is sinking.

1. For example, the crack of the wall paint layer is the cracking of the wall paint layer, so in this case, it is generally the crack on the surface of the wall, and the reason for its cracking is because the quality of the wall paint product is not up to standard, and there is a possibility that it is caused by incorrect operation during the construction process. If it is only a crack in the surface of the paint film, then it is relatively easy to deal with in this case, just sand the crack off with fine sandpaper, and then choose the same color to re-brush it.

2. If the crack of the wall structure layer is the crack of the structural layer of the wall itself, it will lead to cracks on the surface of the wall in this case. As for how to repair wall cracks, generally speaking, there are two kinds in this case, the first reason is that the original wall itself has cracks, which can be dealt with in the later decoration process. There is also a situation that there is no cracking during the decoration, but in the later stage, there may be uneven settlement of the foundation, large temperature changes, etc.

Then you are talking about the problem of the structural layer of the wall.

Question: How to repair the cracks in the wall itself.

I see if you're ** asking you a question.

No, I'll check it out for you.

Ask how to deal with the wall, and it is sure that it is not demolished and repaired.

It is not easy to repair the cracks in the load-bearing wall caused by the subsidence of your foundation. Two temporary columns can be erected near the load-bearing wall and then repaired to the wall.

However, it is not recommended that you do it yourself, you can ask a professional to come to your door to see the situation and then determine the construction method.

It can be repaired by grouting the foundation, increasing the number of reinforcements, or increasing the load capacity of the foundation. First of all, the foundation reinforcement treatment is done, and the wall crack is filled and reinforced with C2000 reinforcing agent, and then a certain amount of concrete is injected and smoothed with cement mortar. Then dig a certain number of pile holes in the foundation, put in an appropriate amount of gravel, and finally insert the grouting pipe into the soil under the house and between the house and the stream, and squeeze it densely, mainly playing a stabilizing role.

Question: I'm a bricklayer myself, but I haven't done wall crack repair, but it's a two-story building, and the crack is still on the first floor.

It's been a long time and I still can't say.

Then this difficulty is quite high, it is recommended to find a special professional to help you deal with it. First, the foundation should be reinforced, and second, the beam should be strengthened to ensure integrity.

You misunderstood me, I told you everything I knew, I'm sorry I didn't help you. [Grievances].

Load-bearing wall openings are divided into transverse and vertical directions.

There are five reasons for vertical openings

The first is that there are cracks in the insulation layer of the original house, which leads to cracks in the wall after decoration;

The second is that the wall is repaired and painted improperly after slotting, resulting in cracks in the wall shrinkage;

The third is that the ratio of cement is not accurate when plastering, and it is easy to crack if the ratio is high;

The fourth situation is that the ratio of wall putty is improper or uneven scraping;

The fifth is that the ratio of latex paint and water is not suitable, and the above non-standard operations will lead to cracking of the wall.

There are two reasons for transverse openings

1. When the concrete is poured, the construction joints are not handled well.

2. When the concrete is poured, the vibration is not in place, and the concrete is formed in the process of coagulation and hardening.

The steps to repair cracks in the wall are as follows; 1. Use a putty knife to scrape out the width of the gap, and scrape it into a figure-eight shape, with the outer width and the inner narrow.

2. Fill the gap with dry powder of gypsum block, and the depth of the plugging is greater than or equal to 30-40mm, which does not need to be filled with the wall, and needs to be lower than the wall.

3. Paste glass cloth or cowhide notes after brushing glue in the gaps.

4. Scrape the putty 2-3 times and smooth it with the original wall, and polish it with sandpaper after drying.

5. Adjust the wall paint, brush the sample first after the paint is adjusted, compare it with the wall color after drying, the color is close, the color difference is not large, and then paint the wall.

6. If there are only small fine cracks on the wall, it can be covered with paint; If the crack is relatively large, it needs to be covered with putty and then covered with paint; If the crack is large and deep, you need to shovel off the original putty and fill the gap with elastic putty again.

1. If there are cracks in the wall paint of the load-bearing wall, you only need to use sandpaper to slowly polish the cracks smooth, and then use a roller to paint the same wall paint to block them. 2. After the cracks in the load-bearing structure wall, first use cement mortar to fill the cracks, and then paint the wall at the cracks after they are completely dry, and the cracks will be solved. Related knowledge popularization:

1. The cracks in the load-bearing wall are the implantation of the pipeline after the completion of the house, open up the hole, and destroy the integrity of the wall, which may also be a problem of the construction party, so a comprehensive inspection must be carried out when buying a house. And for safety reasons, when the house is decorated, the load-bearing wall in the house cannot be modified or drilled, which will destroy the load-bearing capacity of the wall, which is an illegal act. 2. The cracks in the load-bearing wall may also be due to the problem of the foundation, due to the uneven settlement of the foundation, cracks are generated, this crack is generally oblique, and there will be no crack in the big situation, if it is a large house, it can not live in people, so the small cracks that appear because of the settlement only need to be repaired with cement mortar, and will not affect the safety performance.

Dear, I'm glad to answer for you: Is it dangerous to have cracks in load-bearing walls? Answer: The problem that the cracks in the load-bearing wall will be dangerous is not big, but it is also recommended to ask professionals to repair it, if it is too large, it is recommended to deal with the load-bearing wall as soon as possible, which refers to the wall that supports the weight of the upper floor, which is a black wall on the engineering drawing, and it will destroy the entire building structure if it is knocked out; The non-load-bearing wall refers to the wall that does not support the weight of the upper floor, and only plays the role of separating one room from another.

Cracks in the load-bearing walls of buildings may be caused by architectural design or construction quality problems, or they may be caused by aging and wear and tear caused by the age of the building. Whatever the reason, it is critical to repair and treat them in a timely manner, otherwise the cracks may become more serious and even lead to building safety hazards.

1.If the crack is small and not deep, you can observe it for a period of time before further treatment, if you find that the crack has not changed or has not changed much, you can consider using a simple method such as caulk to fill it.

2.Find the cause of the crackIf the crack is severe, you need to find the cause of the crack formation. It can be caused by land subsidence, or it can be caused by problems in the design of the building. It needs to be carefully inspected and analyzed by a professional architect or engineer.

3.Reinforcement of the wallWhen the cause of the crack is determined, the wall needs to be reinforced. If there is a flaw in the architectural design, it is necessary to find a professional architect to redesign; If it is a problem such as land subsidence, it can be reinforced by adding supports.

4.Completely repair the crackIf the crack is large, it needs to be completely repaired until it is completely filled, and the strength after repair should be guaranteed. Repairs can be done with specialized caulk or intumescent resins.

In short, cracks in the load-bearing walls of buildings are a problem that needs to be dealt with in a timely manner. When dealing with it, it is necessary to find a professional architect or engineer to conduct testing and analysis, and at the same time, it is necessary to take into account the load-bearing capacity of the wall, and be cautious when making treatment plans.
