Concrete Walls can be constructed from precast concrete, poured concrete, concrete block, stucco concrete, stamped concrete and colored concrete. Precast walls can be reinforced with steel ribs. Poured concrete walls can be used for a foundation or as a retaining wall. Concrete block walls can also be used in a foundation or as a retaining/decorative wall. Stucco walls serve more as texture. It is made of a thin concrete layer that is used over an existing wall. Stamped walls are similarly created to poured concrete walls in the way it is molded. Colored concrete walls also are created by poured concrete techniques.
