You can place your shipping container directly on the ground, however, it’s important to monitor it as it may start to sink or tilt depending on the integrity of the ground it’s standing on, causing the doors to misalign slightly and not close properly. It’s recommended that you create a 3-inch deep gravel pad to place the container on, as this allows for ample drainage and prevents irregularities in the ground. Alternatively, you can place your shipping container on wood 4x4’s or railroad ties.
