Container House Roof Waterproofing

Container house roof waterproofing can be achieved by selecting appropriate waterproof materials, properly handling waterproofing at key parts, and reasonably designing the drainage system. Details are as follows:

Selecting appropriate waterproof materials

• Water-based high-chlorinated coating: With water-based high-chlorinated polyethylene resin as the main film-forming component, the paint film is dense and water-blocking, resistant to acids, alkalis, salt spray, and industrial corrosive gases. It dries quickly, has good flexibility, can effectively delay the rusting and aging of the base material, and has good environmental performance. It is suitable for the anti-corrosion parts of containers and can also be used for roof waterproofing, withstanding long-term erosion from rainwater, salt-alkali fog, etc.
• Steel structure roof waterproofing system materials: Composed of a base waterproof coating, a surface waterproof coating, and a woven polyester fabric. Using high-quality 100% pure acrylic emulsion from the United States as the base material, supplemented with high-quality auxiliary materials and precision processing, and enhanced with polyester fabric to form a seamless waterproofing system. It has super-strong tensile strength, UV resistance, anti-aging properties, a service life of up to 25 years, and a 10-year quality guarantee. It is particularly suitable for old roofs with existing waterproof layers.

Properly handling waterproofing at key parts

• Panel seams: The standard process involves using waterproofing membranes in combination with sealant for full sealing, ensuring seamless sealing at the seams. For example, in box-type movable packing container houses, the seams at both ends of the folded iron sheet layer on the roof need to be sealed with structural adhesive. Poor sealing can lead to rainwater leakage.
• Window and door openings: Sealing treatment is also essential to prevent rainwater from seeping in through the edges of windows and doors. High-quality container space capsule shops adopt reasonable processes at window and door openings to avoid water leakage.
• Roof panel joints: Design a reasonable drainage slope and ensure that the panels are lapped in the direction of water flow to ensure that rainwater can be discharged smoothly, reducing the pressure and erosion of accumulated water on the roof.

Reasonably designing the drainage system

• Gutter design: Ensure that the gutters have a horizontal slope and that the outlets are reasonably designed to prevent water accumulation in the gutters during heavy rain, which could lead to backflow. At the same time, proper anti-corrosion treatment of the gutters is necessary to prevent rust erosion or blockage of the outlets by debris, which could cause water leakage.
• Overall drainage planning: According to the layout of the container house and the surrounding environment, reasonably plan the drainage route so that rainwater can be quickly and smoothly discharged away from the house, reducing the impact on the roof and walls.
