Our shipping containers and storage containers sit directly on the ground. No surface prep is required, as the only parts of the container that touch the ground are the four corner posts. In fact, the bottom of the container actually sits 5-6” above the ground.
**However, we strongly recommend that you choose a site that is as level as possible. If the storage container is not level, the container doors may be hard to open and close easily. The surface area where you place your container should also have adequate drainage to avoid sinking.
