Builders call anchoring the process of securing wall frames to the foundation. Although load-bearing walls must be anchored to foundations with high-strength bolts, walls that do not support a structural load, called partitions, are usually fixed to the foundation with lightweight concrete screws and nails operated with gunpowder. Slabs, basements, and narrow spaces are the three main foundation systems used in homes. In humid and coastal areas, it is also sometimes common to place houses on poles.
Most houses have a raised perimeter base that supports floors and load-bearing walls. Some are built on a flat concrete slab, which serves both as the base for the structure and as the ground floor of the house. Others, especially vacation homes and small, old houses, often rest on a series of concrete pillars. Basement foundations and mezzanines have walls around the perimeter of the foundation.
These walls are usually built with concrete masonry units or by erecting wall shapes that will be filled with poured concrete. The walls of old houses were made of bricks, and the walls of very old houses may have been made of stone. This type of foundation uses a small space of 36 to 48 inches (0.91 to 1.22 meters) of conditioned area at the bottom of the modular home. Of these types, basement and mezzanine foundations are the most popular foundations for modular homes.
If the space doesn't give your home enough height, it could also make it prone to termite infestations or the effects of high humidity. It has more space in the foundation and, before installing the modular house, concrete pillars and walls will be placed to support the space. You can attach a modular home to the foundation using nailing strips, nailing plates, screws and bolts approved by an engineer to attach it to the threshold plate.
