Dampproofing of Container Houses by the Pond
Dampproofing of container houses by the pond requires a comprehensive approach involving material selection, structural design, construction treatment, and routine maintenance. Specific measures are as follows:
1. Material Selection and Coating Treatment
The core of dampproofing container houses lies in blocking moisture penetration. Prioritize the use of dampproof coatings with excellent performance, such as specialized dampproof paints that resist mold growth, provide efficient waterproofing, and are corrosion-resistant. These can maintain the integrity of the container surface over the long term, preventing contamination, odors, and structural damage caused by moisture. Additionally, incorporating dampproof substrates (such as rock wool, glass wool, or polyurethane sandwich panels) within the wall panels can further enhance thermal insulation and dampproofing effects.
2. Bottom and Ground Treatment
The environment by the pond has high humidity, and ground moisture can easily infiltrate the container through the bottom. It is necessary to lay dampproof pads at the bottom of the house and use ventilation channels to divert ground moisture. Even when placed on unhardened ground such as mud or grass for extended periods, this can effectively reduce the risk of dampness and mold. Meanwhile, the container foundation should be elevated (e.g., using independent pile foundations) to avoid direct contact with the ground and further block the upward path of moisture.
3. Sealing and Ventilation Design
Inadequate sealing can lead to the infiltration of external moisture, while poor ventilation can cause internal condensation. It is essential to focus on checking the sealing of doors, windows, container joints, and roof gutters. Regularly replace sealant (recommended every 5-7 years) and clear roof debris to prevent water accumulation and corrosion of steel plates. Additionally, dampproof thermal insulation cotton can be applied to the inner walls of the container to buffer diurnal temperature variations and reduce water vapor condensation caused by sudden drops in roof temperature. Alternatively, promote air circulation by stacking goods reasonably and leaving ventilation gaps.
4. Routine Maintenance and Monitoring
Dampproofing requires long-term commitment. Inspect welds, corners, and the bottom of the container annually for moisture-prone areas, and immediately sand and repaint any rust spots found. Adjust the recoating cycle based on environmental humidity (7-10 years in humid southern regions and 3-5 years in coastal areas). Meanwhile, place desiccants (such as high-moisture-absorbing container desiccant strips) inside the container, hanging them on both sides of the roof near moisture accumulation areas to absorb excess moisture and reduce condensation risk.
