Abstract: This invention relates to methods and processes which may be used to construct modular buildings, floors, wall, partitions and roofs. A metal or plastic framework is assembled and covered with an absorbent material onto which a polymer substrate is applied. A variety of exterior finish materials may be attached to the substrate. Utility services are modularly installed in each section prior to the wall void being foamed for added strength. An interior finish surface is then applied to the modular section. The modular sections are transported to the job site for final assembly and interconnection.
