Concrete is used in concrete foundations and raised slab foundations. Concrete foundations refer to concrete walls where poured concrete is impractical. Raised slab foundations involve poured concrete with reinforced steel bars.

Concrete foundations are hollow concrete blocks walls measuring 16 inches long by 8 inches wide by 8 inches high. The blocks have reinforced steel bars put through them and are often filled with concrete.
Raised Slab Foundation
Raised slab foundations feature a poured concrete footing below the frost line. The footing buttresses a poured concrete wall that withstands sliding and movement of the land. The slab of concrete is poured over an insulation and a steel mesh to reinforce the strength of the slab.
Brick Vs. Slab
A concrete brick foundation is better when pouring concrete is impractical, such as on a steep slope or when the mobile home juts off a ledge. Both can be used for single-wide, double-wide, or triple-wide mobile homes. Mobile homeowners who own the land can install a concrete or raised slab foundation to prevent the alterations of the land affecting the mobile home's footing.
