The stability of a building's foundation is crucial because it directly affects the safety and durability of the house. However, residential foundation repairs may cause the wall to crack during the use of the building. In this case, repairs and reinforcement must be carried out. This article will explain in detail how to repair a building with cracks in the wall caused by residential foundation repairs.

Often observe the appearance of the building and other anomalies, such as cracks, sloping walls, bouncing floors, or doors and Windows that do not close properly, which can signal residential foundation repairs. It is first necessary to determine the cause of residential foundation repairs, which may be soil loosening under the foundation, geological problems, soil erosion, etc. Commissioned professional geological engineers to evaluate and analyze the foundation, and determine the severity and cause of subsidence by measuring and analyzing the condition of the building.

Second, foundation settlement repair

1. Foundation settlement repair technology: Tongcheng Soft Foundation uses a new type of special composite material to be injected into the depth of the ground, consolidated with the soil to form a new composite foundation, improves the strength of the soil and the bearing capacity of the foundation, and realizes the inclined flexible lifting and upright of the building. The technology is suitable for complex geological conditions, has high economic benefit, simple and convenient process, and short construction period.

Compared with the traditional correction method that needs to destroy the building structure, the process is complex and time-consuming, Tongcheng soft foundation trenchless repair technology adopts miniaturized equipment, micro-hole treatment, non-destructive and controllable, no need to break, and does not affect the normal life of residents, which can realize the deep strengthening of the building soil, flexible lifting, and restore the building to a balanced state.

2. Drainage treatment: Ensure that the drainage system around the building is normal, reduce water penetration into the foundation, and prevent the foundation from further softening and sinking.

3, regular monitoring: during and after the restoration process, regular monitoring to ensure the stability of the foundation and wall.

Small cracks can be filled with repair mortar or caulk, such as tile glue or plaster, to fill the cracked part; Larger cracks may need to be filled with cement mortar. After the repair is complete, wait for the filler or paint to dry completely, and then sand it to make it consistent with the appearance of the surrounding wall.

Iv. Consultation and quotation

1, professional consultation: dealing with the problem of building deflection caused by foundation settlement requires professional knowledge and experience. Therefore, it is recommended to consult a professional engineer, architect or relevant institution for accurate advice and solutions.

2, insurance claims: if you have home insurance, you can file a claim with the insurance company to cover the cost of repair or reconstruction.

3, the building correction plan quotation: determined by a variety of factors, according to the geological conditions, settlement reasons and site conditions comprehensive consideration, listen to the opinions of professional engineers.
