The foundation is subsided, causing cracks in the wall, so is there a safety hazard in the house?

As we all know, the safety of the house depends largely on the firmness of the foundation. The foundation will be more uneven when the foundation is sunken, and the cracks in the wall will increase the safety hazards of the house. So such a house is definitely not safe.

It can be solved by increasing the support wall and reinforcing the foundation.

There are safety hazards.

Whether the house is firm, mainly depends on whether the foundation is firm enough, if the foundation sinks to the wall cracks, if not dealt with in time, the cracks will become bigger and bigger, so there will be great safety hazards.

There are potential safety hazards, such as small cracks, and grouting can be done on the sunken foundation.

It is necessary to go to the housing quality department to test the safety and quality of the house, determine the level of foundation subsidence, and formulate different remedial plans according to different degrees of subsidence.

If the foundation sinks to a certain limit, there will be cracking or even collapse, not only that, the foundation sinking may also lead to water leakage, so when the foundation sinks, it is not recommended to continue to live, and should be reflected to the relevant departments in time to avoid personal injury.

The user needs to observe the subsidence of the house foundation first, but the specific situation, to formulate a relative solution to the wall cracking. Remedial measures are taken for the location of the cracks in the wall, such as using pressure grouting, etc. It is necessary to set the foundation outside, add a ground beam in the structure, and the current foundation is overhead, and change the force transmission path of the superstructure.

After that, the user needs to observe whether the foundation settlement has been alleviated or stopped, and then formulate a repair method according to the changes. To repair the structure of the house, it is necessary to add a ring beam structure to increase the integrity of the superstructure.

5 reasons why the foundation is subsided, which leads to cracks in the walls of the house:

1.Cracks due to temperature, cracks due to insufficient masonry stiffness, cracks due to insufficient masonry strength, cracks due to uneven settlement of foundations, non-structural cracks (cracks in the stucco layer).

2.Treatment of existing cracksCracks caused by temperature changes are difficult to repair, but there is no danger of collapse of the house. In order to avoid the occurrence of such cracks, it is necessary to solve the problem by solving the difference between the line swelling of the two different materials of the roof and the brick wall.

Generally, the common method is to do a good job of roof insulation.

3.Due to the cracks caused by the insufficient stiffness of the masonry, the brick wall will show flat bending, and at the midpoint of the bending length, there are often horizontal trending cracks. In this case, reinforcement measures should be taken.

Pure cement slurry can be injected into the cracks by pressure grouting, and then methods such as adding pilasters or reinforcing the walls between windows can be adopted.

4.Walls with such cracks are in danger of collapsing due to cracks caused by insufficient masonry strength. Take reinforcement measures.

Generally, it is reinforced by adding pilasters or using steel structure. Due to the uneven settlement of the foundation, the cracks in the brick wall are located in different directions, and the positions and trends of the cracks caused by the lack of strength and stiffness of the wall columns are different. That is to say, the cracks caused by the uneven subsidence of the foundation do not cause the strength or stiffness of the wall columns, and are repaired with cement mortar after the settlement is stabilized.

5.If the stiffness and strength of the wall column components and the house structure are sufficient, then the wall cracks caused by the uneven subsidence of the foundation do not need to be reinforced and reinforced, as long as the cracks are repaired. Crack repair method to improve wall strengthThe crack repair method to improve wall strength adopts pressure grouting method.

One is to use water glass mortar as the binder, and the other is to use 107 glue polymerization cement slurry as the binder.

Remedy:1Under normal circumstances, if the quality of the house is defective, so that it cannot be used normally, the buyer has the right to terminate the contract, request to move out, and require the seller to bear the loss, (that is, the difference in the price of the house and the loss of decoration).

2.If the contract is terminated and the house is vacated, the relationship between the sale and purchase of the house is terminated. If you quit the house but don't get the money, then you don't have a separate creditor-debtor relationship, which means that the developer owes you money, and if you don't pay, you can only claim the arrears according to the move-out agreement.

Cracks in the walls of the house caused by the subsidence of the foundation can be divided into several categories, and the residents can solve the problem in combination with their actual situation.

If there is a crack in the wall, will it be a subsidence of the foundation? :Hello! Glad for your question.

Not necessarily, if it is the cracking of the decoration layer, it has nothing to do with the foundation, and the foundation has subsidence, which is basically the cracking of the wall and floor slab. 1. Temperature cracks - the most common house cracks, which have little impact on the safety of the house structure, this kind of crack only affects the indoor appearance of the house, and will not affect the safety of the house.

2. Settlement cracks - when the settlement development is slow and there is a weakening trend after the occurrence of settlement cracks, the cracks should be repaired after the cracks are stabilized. It takes 2-5 years for the foundation of a new house to stabilize and you don't have to worry too much about the possibility that the walls will crack due to the subsidence of the foundation after the cracks are repaired. If the crack has little impact on the overall aesthetics of the house, it can be repaired after the first repair.

The repair is generally filled with cement mortar, polymer mortar or elastic putty and gypsum, and the caulking tape is pasted. 3. Structural cracks - ordinary decoration methods cannot be repaired, and professional building structure personnel must be found to take corresponding measures according to the actual situation. 4. Cracks in latex paint on the surface Wallpaper cracks:

If it is only a crack on the surface of the paint film, use fine sandpaper to polish the crack off and repaint it. If the wallpaper is cracked at the joint, moisten it with warm water and re-apply the wallpaper glue to paste. 5. Putty screed cracks:

If the crack has penetrated deep into the putty layer, you can first use a sharp tool to expand the crack to a cone size, fill in the caulking plaster and polish and level, paste the mesh cloth or kraft paper and then use putty to level, and finally paint or paste wallpaper according to the normal process. 6. Cracks in the plastering layer of cement mortar: If there is a large area of hollowing in the plastering layer, the original plastering layer should be knocked out, the plastering layer of cement mortar should be redone, and then painted or wallpaper should be painted or pasted according to the normal process after leveling.

However, the cost will be relatively higher after this treatment, and the owner can choose the repair method according to his own economic ability. If there is only a large area of cracking, there is no sand, hollowing, or falling off, you can paste a good cloth all over the wall, and then paint or paste wallpaper according to the normal process. The relatively low cost is to nail a layer of gypsum board directly on the original wall, which requires environmentally friendly milky white rubber and steel nails to be used at the same time.

7. Cracks at joints: It is recommended to repair the whole building after the deformation tends to be stable, and the repair within a short period of time is prone to recurrence.

1. Simply doing anti-cracking treatment on the wall cannot solve the current problem. At the same time, it will also cause very large safety hazards, it is recommended to directly find the housing quality department to identify the safety of the house, if the settlement is too serious, it is recommended to move away from this dangerous place and rebuild the house. 2. You can find a design unit with relevant qualifications to make a reinforcement plan to prevent the building from sinking, and then implement it.

Related knowledge popularization: 1. The sunken wall can be strengthened and the gaps can be repaired. 2. The cracked part of the wall is caused by the uneven settlement of the foundation.

First of all, it is necessary to observe whether the cracked wall is likely to continue to expand; If it is further expanding, it is very dangerous; If it does not continue to expand, the mortar at the crack can be removed with a shovel, and then a layer of steel wire mesh can be hung on top of it, and then filled with plastering and putty. After the putty is dry, apply a layer of latex paint. 3. The foundation generally refers to the soil or rock mass of the load-bearing foundation under the building, and does not belong to the component of the building.

However, it plays a very important role in ensuring the durability of the building, and there are two types of foundations: natural foundation and artificial foundation. The natural foundation is a natural soil layer that does not need to be artificially reinforced, and the artificial foundation needs to be reinforced in the later stage, such as sand cushion mixed with ash soil.

The foundation of the house is falling, which is a very dangerous situation. The cracking of the sinking wall of the house foundation does not necessarily collapse, first we analyze the causes, and then use the foundation for grouting to increase the number of reinforcement or increase the bearing capacity of the foundation for repair.

Then to strengthen the foundation, C2000 reinforcing agent is used to reinforce the cracks in the wall, and then a certain amount of concrete is injected and filled with cement mortar. Dig a certain number of pile holes in the foundation, put some gravel, and then insert the grouting pipe into the soil under the house and the house and the stream to compact it, which can have a stabilizing effect.

The causes of wall cracking are:

1. After the house is built, the foundation will sink. If the settlement of the foundation is uneven, the large settlement part and the small settlement part will be displaced, resulting in shear force and traction force in the wall. Cracks occur when these additional internal forces exceed the tensile and shear strength of the wall itself, and these cracks settle with uneven foundations.

2. The horizontal crack of the wall between the windows is caused by the large settlement of the foundation and the strength of the upper unit, so that the wall between the windows bears a large horizontal shear force, and horizontal cracks appear between the upper and lower positions. Caused by the reaction force that occurs after the sill wall is subjected to load. <>

If the foundation of the house sinks, the house will crack from the first floor upwards, and the first floor will have the largest rip, and the further up the floor will be, the smaller the rip will be.

There are many reasons why the foundation of the house will sink, the first reason may be because the foundation was not reinforced when it was built, the second reason may be because the soil used in the foundation is relatively soft, and the third reason may be that the weight of the building is relatively heavy, exceeding the gravity of the foundation.

In fact, in order to save costs, many real estate developers now lay the foundation is not particularly deep, so after a long time, the foundation will sink, and the consequences of the foundation sinking are still relatively serious, which is easy to affect the quality of the house, so many people still pay more attention to this aspect.

When rural people build a house, they will spend a lot of time on the foundation, and the foundation will be deeper, in this case, the quality of the house will be better, and the foundation will not sink in the later stage.

If the foundation of the house sinks, the house will crack from the first floor upwards, and the first floor will have the largest rip, and the higher you go, the smaller or less the rift will become.
