What Kind of Foundation Would a Factory-Built Home Be Set Up On?
There are two basic quality home foundations. The Basement Foundation is a home supported on a cement wall around the perimeter of the home and down the center of the home on the floor jacks. Exterior cement walls usually extend five feet or more into the ground to get below the frost line so the foundation will not be moved by frost as long as the home is heated. The cement slab foundation is where the factory-built home is placed on a six-inch thick slab. Cement blocks are placed every eight feet under the four steel I-beams the home was transported on, plus the home is supported every 20 feet down the middle of center line of the home with cement blocks. Most factory built homes sales centers consider this method a complete support system.

Styrofoam insulation is glued to the inside of the perimeter wall and down the outside
