Why Proper Burial Of Shipping Container Is Important
If you’re thinking of putting your shipping container underground, there’s a few reasons why you should make sure it’s buried properly:
- Structural Stability and Load Distribution
Properly burying the container makes sure that it can withstand the immense ground pressure from surrounding soil and surface loads. An appropriate load distribution also protects the integrity of the structure and prevents settling issues over time.
- Water Management and Moisture Control
Having a proper drainage system prevents water accumulation around the container and protects it against corrosion. Additionally, strong barriers against moisture prevent interior dampness that could lead to mold growth and air quality issues.
- Long-term Durability and Maintenance
Well done burials minimize the need for frequent repairs and maintenance and can make inspections and repairs easier. They also extend the container's lifespan and protect your investment.
- Safety and Emergency Preparedness
When burying a container, make sure to install and maintain an adequate ventilation system. Additionally, have some emergency exits and access points to protect against any unforeseen events. Burying the container at the appropriate depth and reinforcing it can help protect it against natural disasters and extreme weather events.

Factors To Consider Before Putting A Shipping Container Underground
New containers are a better choice for a bunker due to their superior quality.
1. Structural Integrity
Shipping containers have a monocoque construction, meaning the corner frames bear most of the weight. Intense ground pressure can cause the walls to cave in if not properly reinforced.
2. Reinforcement
Modifying the shipping container with additional support is the most effective method of reinforcement. Welding strong steel bars along the roof and periphery of the container can increase its load-bearing capacity. You can also build a steel cage around the container and fill it with stones to create a barrier between the soil and the container.
3. Burying it Well
Dig a hole with about 4 feet of additional space along each side of the container to accommodate the reinforcements.
4. Upside Down Burial
Planting a container upside down allows the thicker floors to act as the roof of the bunker, which needs to be strong to handle the ground pressure.
5. Foundation
Use a stable and durable foundation like concrete so the container remains secure. Ground foundations act as anchor points and help distribute the container's weight evenly.
6. Weight Considerations
An empty 20-ft shipping container weighs about 4,400 lbs, while an empty 40-ft shipping container weighs approximately 8500 lbs. Unless the ground is rock-solid, the bottom of your container could sink over time.
7. Location and Site Conditions
Select a flat and accessible area with good drainage to prevent water accumulation around the container. Evaluate the soil type, drainage conditions, and terrain slope to understand the ground's stability.
8 Regulations and Permits
Check local regulations and obtain any necessary permits for installing the container.
