Most container homes don’t fail because of weak concrete. They fail because the foundation ignores how containers actually transfer load into the soil. Slabs and piers are not the real debate. Differential settlement is. In this video, we explain why container homes are point-loaded structures, how uneven soil movement twists rigid steel frames, and why even perfect concrete foundations still fail when soil behavior is misunderstood. This is not a construction tutorial. This is an engineering explanation of why assumptions sink container homes.
