  • Patent number: 9309667
    Abstract: A concrete exterior wall system for residential and commercial construction incorporates interior wood, metal or composite framing members. The wall system solves the problem of erecting heavy, hard to manage solid wall segments as well as time-consuming, complicated multi-piece wall segments. Further, the wall system eliminates the need to frame interior walls for utility access, insulation and interior finishes. Moreover, the wall system eliminates exterior maintenance and structural damage from weather, insects and the like. The wall system incorporates wood, metal or composite material interior framing with a concrete exterior that has a permanent exterior finish. Interior studs allow easy utility installation and finish applications. The shape of the wall units are designed for less weight per linear foot than conventional systems.

  • Patent number: 8393128
    Abstract: The present invention encompasses a process for initially combining and thereafter uniting two or more modular units to one another in order thus combined to be able to form a house body, for instance a cellar-adapted house body. A liquid-resistant layer is advantageously wholly or partly to be able to cover a base slab and in any event lower wall sections allocated to the wall portion, proximal the base slab, in order principally to prevent damp permeation. A first modular unit, with in any event a first open wall portion, is placed on a substrate prepared within a building site, a second modular unit, with in any event a second open wall portion, is placed on the substrate prepared within the building site, so that an open wall portion allocated to the first modular unit will connect to an open wall portion allocated to the second modular unit. The base slab of the one modular unit and the base slab of the second module form a free space defined by the mutually facing edges of the base slabs.
