Container House Damp-Proof Mat
Laying damp-proof mats in container houses is an effective moisture-proof measure that can be combined with other moisture-proof designs to enhance effectiveness. Here is a detailed analysis:
The Working Principle of Damp-Proof Mats
Damp-proof mats are usually laid at the bottom of container houses to directly block the penetration of ground moisture. For example, the simple temporary container houses in Heyuan have damp-proof mats laid at the bottom, paired with ventilation channels to疏导 ground moisture. Even when placed on unhardened ground such as mud or grass for a long time, they are not prone to dampness and mildew. This design effectively reduces the risk of condensation water accumulation at the bottom of the container through a dual mechanism of physical isolation and airflow疏导 (which can be translated as 'airflow guidance' in a more natural English context, but here '疏导' is more about channeling or directing the airflow, so 'airflow channeling' could also work; for simplicity, we'll use 'airflow疏导' as a direct but slightly adapted translation here, or simply 'ventilation' to convey the idea).
Synergistic Moisture-Proof Design of Damp-Proof Mats
The moisture-proof system of container houses is usually a multi-layered structure:
- Wall Moisture-Proofing: Some products (such as the moisture-proof model in Heyuan) add moisture-proof base materials inside the wall panels to form a second barrier.
- Structural Moisture-Proofing: Galvanized steel frames and fire-resistant sandwich panels (filled with rock wool or polyurethane foam) are used, which not only meet fire protection requirements but also block moisture through material properties. For example, the container warehouse in Xiamen uses Class A fire-resistant sandwich panels with a combustion performance of GB8624 B1 or above, which also have moisture-proof functions.
- Construction Moisture-Proofing: Standard installation requires complete accessories such as fixed anchor bolts and damp-proof washers to ensure reliable connections. For example, the residential container houses in Haining explicitly require that the panel structure of the movable prefab houses has no deformation or damage, and that damp-proof washers and other accessories are complete to ensure tightness.
Applicable Scenarios for Damp-Proof Mats
Damp-proof mats are particularly suitable for the following environments:
- High-Humidity Areas: Such as coastal or rainy regions, where container hotels and temporary warehouses require long-term moisture-proofing.
- Unhardened Ground: Places in direct contact with the ground such as mud or grass, where damp-proof mats can prevent moisture from infiltrating from the bottom.
- Movable Buildings: Scenarios requiring frequent disassembly and assembly, such as packing container houses and prefabricated container houses, where damp-proof mats are convenient for reuse and have low costs.
