Prefabricated Concrete House Basement

Prefabricated concrete houses can have basements. Here are the key points regarding basements in prefabricated concrete houses:

I. Structural and Construction Advantages
Prefabricated concrete houses are constructed using precast concrete panels, which provide a sturdy structure capable of withstanding certain soil pressure and groundwater pressure, making them suitable for basement construction. Compared to traditional construction methods, the construction process of prefabricated concrete houses is more labor-saving and efficient, and it is equally applicable to basement construction, reducing the construction period and minimizing the environmental impact of on-site wet operations. For example, the moisture-proof prefabricated concrete houses in Bameng are produced through standardized processes, resulting in high component strength and consistency, good overall structural integrity, and effective resistance to foundation settlement and minor geological disasters.

II. Waterproofing and Moisture-Proofing Techniques
Special attention must be paid to waterproofing in basements. When constructing basements in prefabricated concrete houses, it is essential to ensure that the waterproofing layers on the walls and floors are intact to prevent groundwater leakage. The moisture-proof prefabricated concrete houses in Bameng employ multiple moisture-proofing techniques:

1. Base Isolation Technique: High-molecular waterproofing membranes are laid at the contact layer between the foundation and the walls, forming a physical barrier to prevent the rise of underground capillary water.
2. Structural Ventilation Design: Micro-porous channels are set up inside the walls, utilizing the principle of air convection to expel moisture and maintain indoor humidity at a stable level of 55%-65% over the long term.
3. Surface Treatment Process: Silicate-based waterproofing mortar is used for plastering, whose crystalline structure expands upon contact with water to fill pores, achieving a 'self-healing' effect; hydrophobic coatings are added to the exterior walls to make rainwater bead up and roll off.

III. Ventilation and Lighting Design
Basements typically have poor natural lighting and ventilation conditions, necessitating the use of artificial lighting and ventilation systems to improve the environment. The moisture-proof prefabricated concrete houses in Bameng have been optimized for local climatic conditions, such as using a combination of ground air ducts and roof fans in the ventilation system to achieve dual control of humidity and temperature.

IV. Construction and Maintenance Points
A standardized construction process is key to ensuring the quality of basements, including steps such as site surveying, foundation construction, and wall installation. In terms of maintenance, it is necessary to inspect the integrity of the exterior wall coatings before the rainy season each year, clean the basement vents monthly, and ensure that the surrounding drainage ditches are kept clear with a proper slope. Actual cases show that after 15 years of use, prefabricated concrete houses maintained according to the specifications can still retain 85% or more of their initial moisture-proofing performance.
