Individual circumstances will dictate final design choices. This section shows and describes a variety of reasonable alternatives. No particular approach is considered superior in all cases. There is no one set of perfect solutions recommended practices or details often represent compromises and trade-offs. The challenge at this stage of design is to develop integrated solutions that address all key considerations without significantly complicating the construction or increasing the cost. Included in this group of details are variations in construction systems, insulation location, and moisture management strategies. Figures 4-12 through 4-14 show variations where the slab is the primary location for insulation. residential building industry stakeholders in the design, construction, and code approval of frost protected shallow foundations. The objective of this design guide is to assist U.S. Figures 4-9 through 4-11, and 4-15 show configurations with insulation on the exterior surface of the foundation. the frost depth around a building, thereby allowing foundation depths as shallow as 16 inches for almost all areas of the continental U.S. In this section several typical slab-on-grade sections are illustrated and described. Grade beam with brick veneer/ exterior and under slab insulation.Concrete wall with brick veneer/ under slab insulation.
