Dampproof Measures for Container Houses

Dampproofing for container houses requires a comprehensive approach involving structural design, material selection, construction techniques, and regular maintenance. The specific measures are as follows:

1. Foundation Dampproof Design
Dampproof pads should be laid at the bottom of container houses to block direct penetration of ground moisture. Dampproof base materials (such as polyurethane foam layers or dampproof membranes) should be added inside the wall panels to form an internal dampproof barrier. Additionally, ventilation slots should be set up at the bottom of the container to guide ground moisture away through air circulation, preventing mold growth caused by prolonged contact with unhardened ground (such as soil or grass). For example, dampproof container houses in Heyuan significantly reduce the risk of moisture damage by combining bottom ventilation slots with dampproof pads.

2. Ventilation System Optimization
Ventilation is a core means of dampproofing. Ventilation pipes can be embedded on both sides of the container, with filter-hole lids installed at the outer ends. Inside, honeycomb molecular sieve plates and louvers can be set up to filter moisture from the air while promoting air circulation. Moreover, ventilation balls can be installed on the top of the container to expel hot and humid air through natural convection, reducing internal humidity. For example, a patented container house design achieves efficient dehumidification by combining ventilation pipes with ventilation balls.

3. Waterproofing and Drainage Treatment
Container houses should be properly waterproofed on the roof by applying waterproof glue or laying waterproof membranes to prevent rainwater penetration. The ground level should be higher than the surrounding environment, and drainage ditches should be dug around the container to prevent waterlogging and backflow. During the summer rainy season, a gable-shaped canopy can be added on top to guide rainwater away quickly. For example, residential container houses in Wujiang District, Shaoguan, effectively reduce rainwater erosion through elevated ground levels and drainage ditch designs.

4. Material Selection and Construction Details
The walls should adopt a three-layer structure: an outer layer of anti-corrosion color-coated steel plates to reflect sunlight, a middle layer of polyurethane foam to block heat conduction, and an inner layer of fireproof gypsum boards paired with dampproof membranes to jointly control temperature and humidity. The outer walls should be sealed to prevent humid air from entering the interior, while moisture-resistant and heat-insulating cotton should be attached inside the house to further block moisture. For example, container houses in Jiangxi enhance their dampproof performance by combining sealed outer walls with moisture-resistant products.

5. Regular Maintenance and Inspection
Regularly inspect the container for rust and promptly remove rust and apply paint for maintenance to prevent rust from damaging the dampproof layer. Keep the ventilation system unobstructed and clear any blockages in the filter holes and ventilation slots. For example, container houses in Guangxi require regular inspections of hidden works (such as dampproofing and waterproofing) to ensure long-term effectiveness.
