Is It Practical to Use Old Containers for Buried Storage?

Selecting the Right Containers

When repurposing old containers for buried storage, look for durable, airtight materials like food-grade plastic or metal drums. A 55-gallon drum is a good size for storing small to medium-sized root cellars, and can be easily buried up to 3-4 feet underground. Avoid using containers with rust or sharp edges, as these can compromise the safety and integrity of the storage space.

Preparing the Containers

Before burying the containers, clean and disinfect them thoroughly to prevent contamination. Remove any labels or residue, and apply a food-grade coating to prevent rust or corrosion. For metal containers, consider applying a 2-3 mil epoxy coat to further protect the surface. When preparing the site for burial, ensure the container is at least 12 inches underground, and cover it with a layer of gravel or sand to prevent moisture buildup.

Safety Considerations

When using buried containers for storage, it’s essential to consider safety factors like accessibility and ventilation. Drill a 1-2 inch hole in the top of the container for air exchange, and consider adding a roof vent to prevent moisture buildup. When accessing the storage space, use a secure lid or hatch to prevent accidental opening or exposure to pests. Additionally, consider adding a layer of insulation, like straw or foam board, to maintain a consistent temperature within the storage space.
