Container mounting is not necessarily better than ground mounting, it’s just different. Container mounting suits situations that require greater levels of clearance, as the domed design of our structures means that clearance on the sides is limited and floorspace is encroached upon if you choose to mount directly on the ground.
The other major benefit of container mounting versus ground mounting is that the ground will remain undisturbed (when ballast is utilised). Rather than having to penetrate earth to secure your container shelter, you can place a container in the spot you want to erect the structure, and simply weigh it down with ballast to secure it. This makes installation far easier (and less damaging), particularly when erecting a structure on a hard surface.
