What to Do If the Prefabricated Floor of the House Sinks

Immediate action is required if the prefabricated floor of your house sinks. After identifying the cause through professional assessment, take appropriate measures such as repair, reinforcement, or legal action to ensure the safety of the house.

Preliminary Assessment and Cause Identification

• Self-Observation: First, observe the surrounding environment of the house to check for any new construction activities, such as excavation or pile driving, which may affect the stability of the foundation. At the same time, inspect the internal structure of the house to confirm whether there are any unreasonable modifications, such as the removal of load-bearing walls or changes in room layout, which may disrupt the original force-bearing system of the house and lead to the sinking of the prefabricated floor.
• Professional Inspection: Hire a qualified house appraisal agency or structural engineer to conduct a comprehensive inspection. They possess professional knowledge and equipment to thoroughly analyze the specific causes of the sinking of the prefabricated floor, including soil quality issues, such as soft or unevenly settled foundation soil; design and construction defects, such as insufficient load-bearing capacity design of the prefabricated floor or substandard construction quality; and external factors, such as the impact of natural disasters like earthquakes and floods.

Targeted Measures Based on the Cause

• Responsibility of the Construction Party: If the house is within the warranty period, in accordance with the "Regulations on the Quality Management of Construction Projects", require the developer or construction unit to assume repair responsibilities and retain written evidence, such as repair notices and communication records. If the construction party does not cooperate, file a complaint with the construction administrative department and use administrative power to urge it to fulfill its responsibilities.
• Responsibility of Third Parties: If the sinking is caused by third-party reasons such as adjacent construction or damage to underground pipelines, collect relevant evidence, such as construction approval documents, construction records, and on-site photos, and claim compensation from the third party, requiring it to bear the repair costs and other losses caused by the sinking.
• Self-Repair and Reinforcement: If the cause of the sinking is unrelated to the construction party or third parties and the house is out of the warranty period, hire a professional building reinforcement company to formulate a reinforcement plan and supervise its implementation. Ensure that the reinforcement plan is scientific and reasonable and that the construction quality meets the standards to safeguard the safety of the house.

Legal Approaches and Rights Protection Advice

• Negotiation and Mediation: Negotiate with the responsible party to clarify the repair time, method, and compensation matters. If negotiation fails, seek mediation from real estate management departments, consumer associations, and other institutions, and use the power of third parties to facilitate an agreement between the two parties.
• Legal Litigation: If mediation is unsuccessful, entrust a lawyer to send a lawyer's letter to the responsible party or file a lawsuit with the competent people's court. Provide sufficient evidence to support your claims and safeguard your legitimate rights and interests through legal channels.
