Dujiangyan Prefabricated Slab House Renovation
When renovating a prefabricated slab house in Dujiangyan, it is essential to focus on waterproofing and floor protection, while also selecting a suitable renovation company. Here are some specific considerations and suggestions:
I. Waterproofing is Key
Due to the structural characteristics of prefabricated slab houses, waterproofing is particularly crucial. During renovation, special attention should be paid to waterproofing in areas with water usage, such as bathrooms, kitchens, and balconies. The ground waterproof layer should be applied to the wall to a height of at least 30 centimeters, and the waterproof height on the walls of the shower area is recommended to be over 1.8 meters. If the original waterproof layer is aged or damaged, it should be completely removed and reapplied, ensuring no leakage during the closed-water test (water storage for 24-48 hours) before proceeding to the next step. Additionally, the joints between prefabricated slabs are prone to leakage and should be filled with waterproof mortar or specialized sealing materials, and coated with waterproof paint to enhance sealing.
II. Caution During Demolition
Prefabricated slabs are typically thin (about 8-12 centimeters), so care must be taken during the demolition of floors (wooden or tiled). Avoid using high-intensity tools like impact drills to directly strike the slab. It is recommended to manually remove the surface materials first, then carefully clean the base layer with tools like electric hammers, continuously observing the slab's condition to prevent puncturing, which could cause leakage to the floor below or structural damage. If walls need to be removed, confirm whether they are load-bearing structures. For non-load-bearing walls, reinforcement of the prefabricated slab ends is necessary after removal to prevent stress concentration and cracking.
III. Suggestions for Selecting a Renovation Company
- Le Meijia Decoration: As a local enterprise in Dujiangyan, it offers various decoration styles such as modern simplicity, new Chinese style, and Nordic style, with services covering the entire process from design and construction to soft decoration matching, suitable for homeowners pursuing personalized designs.

When selecting, verify the company's qualifications (such as construction qualifications and safety production licenses), review past cases, and sign a detailed contract specifying the project duration, material brands, and after-sales terms.
IV. Other Considerations
Prefabricated slab houses generally have poor sound insulation; consider adding soundproof cotton or acoustic panels to the ceiling or walls. During circuit renovation, avoid slotting in the prefabricated slabs; it is recommended to use exposed wire channels or shallow wall slotting. For renovation materials, choose lightweight options (such as light steel keels and aluminum扣板 (Note: '扣板' is translated as 'cladding panels' here for clarity, but 'aluminum ceiling tiles' might be more commonly used in some contexts)) to reduce the load on the slab.
