The substructure upon which a manufactured home rests is a critical element of its overall stability and longevity. This supporting system provides a level surface, anchors the dwelling against wind and seismic forces, and separates the living space from the ground, mitigating moisture and pest intrusion. Examples of these structural supports range from simple concrete blocks to more elaborate perimeter wall systems.
A stable and well-constructed undercarriage is essential for several reasons. It preserves the structural integrity of the residence, preventing sagging floors, sticking doors, and other issues associated with uneven settling. Furthermore, a proper setup can significantly improve energy efficiency by minimizing air infiltration. Historically, the evolution of these support systems reflects advancements in engineering and building codes, moving towards more durable and secure solutions to protect the investment.
