Waterproofing for Container Houses

Waterproofing for container houses requires a comprehensive approach covering material selection, construction techniques, and routine maintenance:

I. Material Selection

Waterproofing materials for container houses should be selected based on the operating environment and structural characteristics. Water-based high-chlorinated coatings use water-based high-chlorinated polyethylene resin as the main film-forming component, providing a dense, water-blocking film that is resistant to acids, alkalis, salt spray, and industrial corrosive gases, making them suitable for anti-corrosion and waterproofing treatment of container roofs and exterior walls. Before application, the substrate surface must be cleaned of rust, oil, and dust, and the coating should be applied in layers using rolling, brushing, or spraying methods to ensure a complete, leak-free coating. Water-based alkyd container-specific paint is a single-component, eco-friendly coating that combines waterproofing, rust prevention, corrosion resistance, and aesthetic enhancement, suitable for decorating and protecting galvanized substrates with fast drying times to accommodate fast-paced production. Structural sealants are used to seal gaps in container bodies, and products with excellent wetting and spreading properties should be selected to avoid edge shrinkage or pinholes caused by surface tension differences.

II. Construction Techniques

Waterproofing construction for container houses must strictly adhere to technical specifications. Roof waterproofing should focus on panel seams, door and window closures, and roof拼接 (joint) positions, using waterproof membranes for full sealing and designing appropriate drainage slopes to ensure proper panel overlap and seamless sealing. In rainy southern regions or island environments, enhanced waterproofing techniques for roofs and corners are necessary. Exterior wall waterproofing involves addressing wall cracks, window frame gaps, and damaged exterior wall insulation to prevent rainwater infiltration through these openings. Coating application requires controlling the ambient temperature between 5-35°C, maintaining moderate humidity, allowing sufficient drying time between coats, and protecting the coating from rain during curing.

III. Routine Maintenance

Regular inspections and maintenance are essential for waterproofing container houses. Inspect fasteners to prevent loosening due to roof foot traffic or aging of waterproof gaskets, which can lead to leaks. Clean drainage systems by regularly removing debris from gutters and checking the design合理性 (rationality) of gutter outlets to prevent water backup. Repair coating damage promptly by touching up peeling or chalking coatings to prevent further corrosion from rust.
