Key Takeaways
- Shipping containers are watertight but not entirely waterproof.
- They are built to withstand harsh weather, but prolonged exposure can compromise their integrity.
- Regular maintenance, proper site selection, and additional waterproofing measures improve the water-resistance of shipping containers.
- Conexwest provides quality shipping containers for rent and purchase.
Factors Affecting Water Resistance In Shipping Containers
1. Material and Construction Quality
Shipping containers are primarily made from corten steel, known for its durability and corrosion resistance. The quality of the steel and the construction methods, including the welding of seams and joints, play a significant role in their water resistance.
2. Seal Integrity
Shipping containers have rubber gaskets and caulking, which create a watertight barrier when properly maintained. Over time, however, these seals can deteriorate due to wear and tear.
3. Environmental Conditions
Exposure to extreme weather conditions, such as heavy storms, may affect the container’s watertight capabilities.
4. Modifications and Alterations

Windows and doors need to be sealed properly to maintain water resistance
If not done properly, modifications, such as doors and windows, may create new entry points for water. This is why we highly recommend you only hire a reliable container fabrication company.
5. Age and Wear
Older containers may be more susceptible to leaks due to accumulated wear and environmental exposure. Regular assessments are recommended.

Best Practices For Improving Water Resistance In Shipping Containers
- Regular Inspections and Maintenance: Conducting routine inspections is essential to identify and address any wear and tear. Key areas to focus on include:
- Seals and Gaskets: Check the rubber seals around doors for cracks or deterioration.
- Structural Integrity: Inspect the container for rust, corrosion, or damage that could compromise its watertight properties.
- Apply Anti-Corrosive Coatings: Using anti-corrosive paint or coatings can significantly improve the container's resistance to rust and corrosion - especially important for marine environments.
- Seal Modifications Properly: Make sure that modifications, like windows and doors, are done correctly with appropriate sealing materials and techniques that maintain watertight integrity.
- Control Internal Moisture: To mitigate condensation inside the container, consider using:
- Desiccants: Materials like silica gel or calcium chloride can absorb moisture from the air to reduce humidity levels inside the container.
- Dehumidifiers: Recommended for high-humidity environments to control moisture levels effectively.
- Proper Drainage and Placement: Elevating the container off the ground can prevent water accumulation around it and reduce the risk of water ingress during heavy rains or floods.
- Use Weather-Resistant Materials: For containers repurposed for living or storage spaces, consider adding waterproof membranes or additional seals to improve their water resistance.
- Keep Containers Clean: Regular cleaning can prevent the buildup of debris that may trap moisture or cause corrosion. Address any rust spots immediately to prevent further deterioration.
- Use Plastic Pallets: Plastic pallets help reduce moisture absorption, as plastic is less susceptible to water damage than wood.

Frequently Asked Questions (FAQs)
- Are shipping containers completely waterproof?
No, shipping containers are not completely waterproof. They are watertight, meaning they effectively prevent water from entering the interior. However, prolonged exposure to water or damage to seals can compromise their water resistance.
- How often should I inspect my shipping container?
It's recommended to inspect your shipping container at least once a year. However, if your container is exposed to harsh weather conditions or used frequently, more frequent inspections may be necessary.
- Can shipping containers be used in flood-prone areas?
In areas prone to severe flooding, containers should be elevated on a platform to prevent water accumulation around it. Additional waterproofing measures, such as applying coatings or membranes, can also help.
