Huludao Cement Prefabricated House

The following is information about cement prefabricated houses in Huludao:

Handling of Illegal Construction

There is an issue of illegal cement prefabricated houses in the original green space to the east of Hongshibei Village, Xingcheng City. Starting from May 2025, the party involved expanded the area of illegal construction by dumping construction waste. In July, the installation of six cement prefabricated houses with a total area of approximately 500 square meters, along with supporting projects such as doors, windows, and waterproofing, was completed. The law enforcement department has filed the case and organized demolition, but the demolition was unsuccessful due to the party's emotional agitation and extreme behavior. Currently, the issue has been reported to higher authorities, and it will be dealt with promptly once a solution is studied.

Production Characteristics of Professional Processing Factories

Professional cement house processing factories in Huludao adopt an industrial production model:

• Process Flow: Through CNC mold pressing and high-strength concrete pouring, national standard hot-rolled steel bar mesh is bound inside. C45 or higher-grade concrete is pumped and mechanically vibrated to be dense. After demolding, it is cured to the designed strength under standard conditions.
• Quality Control Advantages: Full-process digital monitoring reduces manual intervention, ensuring dimensional accuracy and strength stability, and avoiding quality fluctuations in manual masonry.
• Product Performance: High structural strength (double-layer and bidirectional reinforcement, with main reinforcement diameter ≥ 10mm), excellent sealing and waterproofing (seamless pouring + special waterproof coating), good thermal insulation (high thermal inertia of the solid structure), short delivery cycle (60% shorter than traditional masonry), and strong adaptability (supporting fine-tuning of non-standard sizes and being compatible with different geological conditions and plot orientations).
• Application Scenarios: Rural self-built houses, temporary construction site command posts, park guard posts, independent garages, municipal supporting facilities, etc.

Key Points for Renovating Old Cement Buildings

The old cement building on Wujin Hutong in Huludao (with an age of over 30 years) has typical problems:

• Structural Defects: The brick-concrete load-bearing walls limit the space for demolition and modification. The lack of a damp-proof layer in the walls leads to efflorescence, moisture absorption, and water seepage. The aging of the exterior wall waterproof layer causes mildew and hollowing.
• Aging Pipelines: Galvanized water pipes are corroded, aluminum wires are overloaded, and cast-iron sewer pipes are blocked and emit odors.
• Construction Difficulties: Narrow building spacing, difficulties in material handling, and noise affecting neighbors.
• Renovation Plan: Remove the original cement layer and apply a damp-proof primer. Install double-layer waterproofing in the kitchen and bathroom. Use the space by the windows and aisles to add built-in storage. At the end of the renovation, focus on dealing with exterior wall water seepage, damaged stair steps in the hallway, and weak indoor thermal insulation (add insulation layers to improve the temperature difference).

Characteristics of Cement Prefabricated Fences

They are assembled on-site using prefabricated components, and the modular design enables rapid installation:

• Structural Performance: High-strength cement components are connected by buckles, which are sturdy, durable, and easy to disassemble and reassemble, with strong resistance to wind pressure and impact.
• Functional Advantages: The surface can be customized with stone-like or wood-like textures, combining aesthetics with sound insulation and thermal insulation performance. The environmentally friendly cement base material has passed inspections and can be recycled, reducing overall costs.
• Construction Efficiency: Hundreds of meters of fences can be erected in a single day. Standardized components are suitable for different terrains, and stable connectors are used to ensure no deformation during long-term use.
