Burying a shipping container might seem like an odd idea, but it can be a smart way to create hidden storage or a safe underground shelter. Whether you want to store valuables, build a root cellar, or make a secret bunker, using a container underground is both cost-effective and creative. However, it’s a massive project that needs careful planning and the right materials. Let’s go through the process step by step.
Step 1: Research and Permits
Before starting, it’s important to do your homework. Different areas have different rules when it comes to digging and building things underground. You’ll need to check with local authorities to make sure you’re following the right zoning laws and safety codes.
In some areas, you might need a permit to bury anything underground. If you skip this step, you could face fines or even be asked to remove your buried container later. Always make sure your plans are legally approved before moving forward.
Step 2: Choosing the Right Shipping Container
Not all shipping containers are the same. The size you choose depends on how much space you need, with common options being 20 ft, 40 ft, or high cube containers. You also need to consider the condition of the container. Used containers might be cheaper, but they could have rust or damage. Look for a container that is in good shape with minimal rust, especially at the bottom where water could cause problems.
You’ll also need to decide whether you want a standard container or one with extra features like insulation (reefer) or ventilation. For a project where the container is buried underground, it’s a good idea to pick a heavy-duty container that can withstand tough conditions.
Step 3: Preparing the Site
Once you have your container, the next step is preparing the site. Choose a flat and stable location, and avoid areas near trees, power lines, or places that might flood. The hole should be large enough to fit the container with space around it for backfilling.
To dig the hole, you can use machines like an excavator or backhoe. Make sure the hole is deep enough to completely bury the container. It’s a good idea to leave 3 to 4 feet of space above the container for backfilling. The soil should be packed tightly to support the weight of the buried container and prevent it from shifting or collapsing over time.
Step 4: Waterproofing and Insulation
One of the biggest challenges when burying a shipping container underground is keeping water out. You can’t just bury it and hope for the best. To prevent water damage, you’ll need to waterproof the container’s exterior. Applying a heavy-duty waterproof sealant or wrapping the container in a waterproof membrane is a good way to protect it.
If you plan to use the container for storage or as a living space, insulation is also important. You can install spray foam insulation or use foam board and reflective barriers to help regulate temperature. This will help protect your items from the heat in summer and the cold in winter.
Step 5: Positioning the Container
Now it’s time to place the container in the hole. This requires precision and the right equipment. Use a crane or another machine to carefully lower the container into the hole.
Make sure the container is level and positioned correctly. It’s important to check that the door is facing the right way and is easy to access once the container is buried underground.
Step 6: Backfilling and Securing the Container
After the container is in place, you can begin backfilling, which means filling the hole with soil to cover the container. Start by adding a layer of gravel around the base of the container for drainage. This helps water flow away from the container and prevents rust.
Then, fill the rest of the hole with soil, compacting it as you go. The more compact the soil, the less likely the container will shift or collapse over time.
Step 7: Final Considerations
Before finishing the job, make sure to think about safety and ventilation. You don’t want your buried underground space to become dangerous. You’ll need to install a ventilation system to allow air to flow and prevent the build-up of harmful gases like carbon monoxide.
Also, make sure there’s an easy way to get in and out of the container, like a door or hatch. You might also want to install a sturdy ladder or steps inside to make access easier.
Conclusion
Burying a shipping container underground is a smart way to create hidden storage or a safe shelter. While it requires careful planning, the right materials, and attention to safety, it’s an affordable way to maximize space. By following the steps—choosing the right container, preparing the site, waterproofing, and ensuring safety—you can successfully bury a container that will last for years.
