Renovation of Stone Prefabricated Houses

The renovation of stone prefabricated houses requires a comprehensive approach that addresses structural safety, functional enhancement, and aesthetic restoration. The specific methods are as follows:

1. Comprehensive Inspection and Assessment
   Before renovation, conduct a systematic inspection of the house, focusing on evaluating the structural stability of walls, foundations, and roofs. Check for cracks, settlement, or material aging issues, with particular attention to the integrity of connections between prefabricated components. For example, if wall cracks exceed 5 millimeters in width or uneven settlement occurs in the foundation, these issues should be addressed as a priority.

2. Structural Reinforcement and Repair

   • Foundation Reinforcement: If the foundation's bearing capacity is insufficient, methods such as widening the foundation, deepening the foundation, or injecting cement slurry can be employed to enhance stability.
   • Wall Reinforcement: For damaged walls, strengthen them by adding reinforced concrete beams and columns internally, applying carbon fiber sheets, or adding support structures; cracks should be filled with high-strength cement mortar and smoothed out.
   • Roof Repair: Replace damaged tiles or waterproofing layers, add roof trusses or support beams to improve wind resistance; thoroughly clean and reapply waterproof coatings to leaking areas.

3. Functional Space Optimization

   • Layout Adjustment: Based on modern needs, remove non-load-bearing walls to add functional areas such as bathrooms, kitchens, or open-plan living rooms, improving space utilization.
   • Equipment Upgrades: Install electrical, heating, ventilation systems, and modern kitchen appliances, ensuring compliance with safety standards; replace old doors and windows with double-glazed or thermal-break aluminum materials for both insulation and aesthetics.

4. Aesthetic and Durability Enhancement

   • Stone Wall Cleaning and Repair: Use high-pressure water jets to remove dirt, vines, and other contaminants, restoring the stone's natural color; fill gaps with concrete or stones that match the original material, sand them smooth, and apply a transparent protective coating.
   • Waterproofing Treatment: Install polymer waterproofing membranes or apply waterproof coatings to walls and floors to prevent rainwater infiltration and structural corrosion.
   • Seismic Retrofitting: Depending on the seismic risk level, add seismic walls, dampers, or base isolation devices to enhance the house's earthquake resistance.

5. Long-Term Maintenance and Upkeep
   After renovation, establish a regular maintenance plan that includes checking for wall cracks, cleaning drainage systems, and testing equipment operation. Conduct specialized inspections of waterproofing layers and structural connections every 3-5 years to extend the house's lifespan.

Precautions: All renovation plans must be reviewed by professional architects or engineers to ensure compliance with local building codes; relevant approvals must be obtained before construction to avoid illegal operations.
