Is the Waterproofness of Container Houses Good?

Container houses generally have good waterproof performance, which is ensured through various aspects such as structural design, material selection, process treatment, and rigorous testing. The specific manifestations are as follows:

1. Waterproof Advantages in Structural Design
The main structure of container houses is made of high-strength steel, which inherently possesses excellent airtightness and corrosion resistance, effectively preventing water penetration. The splicing process uses sealing strips and high-strength bolts for connection, ensuring the airtightness of the joints and preventing rainwater from seeping in through gaps. This structural characteristic provides basic waterproof capabilities, making it particularly suitable for rainy or humid environments.

2. Waterproof Treatment of Roofs and Walls
The roof design adopts a sloped structure, combined with waterproof membranes (such as SBS modified bitumen membranes or PVC waterproof membranes) and drainage systems, to quickly guide rainwater away and avoid water accumulation. The wall section enhances waterproof performance through multi-layer composite materials. For example, a waterproof coating is applied to the surface of steel plates, and sealing strips or polyurethane foam are used to fill gaps, forming multiple protective barriers.

3. Waterproof Performance Standards and Testing
High-quality container houses typically have a waterproof rating of IPX4 or higher, allowing them to maintain indoor dryness under heavy rain conditions with a rainfall rate of 100 millimeters per hour. Their waterproof performance must be verified through simulated rainfall tests (such as continuous heavy rainfall for several hours using a sprinkler system, with no leakage for more than 4 hours considered qualified) and wind pressure resistance tests (verifying stability under conditions of wind at level 10 accompanied by rainfall), ensuring reliability in actual use.

4. Refined Application of Materials and Processes
The thickness of waterproof membranes on roofs is usually between 1.5 and 2.5 millimeters, with sealing compounds applied at joints. Walls use materials such as color-coated steel plates, with waterproof coatings applied to their surfaces and gaps filled with sealing strips or polyurethane foam. In high-temperature, high-humidity, or coastal salt-spray environments, more weather-resistant ethylene propylene diene monomer (EPDM) rubber membranes are selected to adapt to extreme climatic conditions.

5. Industry Standards and Long-Term Guarantees
According to the "Technical Code for Building Waterproofing Engineering" (GB50345) and the "Technical Standard for Container Houses" (CECS 334), container houses must not experience leakage for at least 5 years under normal use conditions. In practical applications, they can effectively resist seawater erosion and rainwater scouring in coastal areas or construction sites, maintaining a dry and comfortable interior.
