Waterproof Performance of Container Houses

The overall waterproof performance of container houses is relatively good, but there are differences in waterproof effects under different brands, craftsmanship, and designs. Long-term effective waterproofing can be achieved through reasonable design and craftsmanship treatment.

I. Influence of Brand and Craftsmanship on Waterproof Performance
Some brands enhance waterproofing through strict craftsmanship. For example, Yunnan Hongfeng's modular buildings adopt unique craftsmanship, with products featuring wind and rain resistance, and an actual service life of up to 50 years, demonstrating stable performance in multiple projects in Yunnan and Southeast Asia. Tongxiang Jiacheng Mobile Panel House Co., Ltd.'s packed containers use a fully welded box structure. In simulated continuous 24-hour heavy rain spray tests, no water seepage occurred at the box joints, with dry interior walls, showing superior waterproof performance compared to bolt-connected boxes (e.g., a certain brand experienced 3 instances of water seepage at the corners in the same test).

II. Key Designs in Waterproof Craftsmanship

1. Joint Treatment: Leakage in container houses often results from inadequate waterproof craftsmanship during production, especially at positions such as roof welds, box body splices, and around doors and windows. Zhongye Zhichuang adopts a multi-layer waterproofing process, combined with weather-resistant waterproof glue and waterproof membranes, offering strong resistance to rainwater erosion and adaptability to outdoor environments.
2. Drainage Optimization: Reasonable design of roof drainage slopes can reduce water accumulation and lower the risk of leakage. For example, some brands optimize drainage systems to prevent gutters from overflowing with water.
3. Material Selection: The use of materials such as high-density thermal insulation rock wool and double-glazed aluminum alloy with thermal breaks not only improves thermal insulation and sound insulation but also indirectly enhances waterproofing. For example, cultural and tourism space capsule shops reduce condensation issues by filling with thermal insulation rock wool and incorporating thermal break insulation technology, while also strengthening waterproofing at roof edges and corners.

III. Precautions for Use and Maintenance

1. Avoid Human-Induced Damage: Treading on the roof during installation and use may cause fasteners to loosen or waterproof pads to age, necessitating regular inspection of joints and fasteners.
2. Regular Maintenance: During later use, regularly inspect the tightness of joints and promptly repair aged or damaged parts to extend the service life of the box.
3. Environmental Adaptability: In rainy southern regions or island environments, strengthen waterproofing at roof edges and corners, such as increasing the coverage of waterproof membranes or using more weather-resistant sealants.
