The footings are deeper than normal, they then build a perimeter wall out of usually cinder block about couple courses high and it is designed to tie the house slab to the Earth so it can't float out of position or. This is done by using adequate drainage and by the use of vapor retarders. By pouring in lifts, the first part of the concrete starts to set up slightly (slake) reducing pressure on the lower forms. This system is used in the low to moderate frost line areas. Most folks we've polled on this are quickly in favor of a concrete pour.

Our stem-wall slabs are constructed in three components: a footer to transfer the load to the underlying soil, a sand foundation and a poured slab with rebar reinforcement. The first of these is to build a stem wall of concrete blocks up to the desired slab level. Even if I change defaults and draw manually I cannot get the interior wall to be a thickened slab or monolithic. This can be done either by building a separate footing/stem wall or just thickening the slab where needed ("mono pour"). In this project, we will learn how to draw a basement or foundation plan.

This appendix presents design examples of the retrofitting techniques for elevation, dry floodproofing, wet. The extensive foundation (which is usually called raft foundation), is a unified foundation that extends throughout the entire area of the columns. and it’s even worse with a basement because it takes 3 trips – once to pour the footing, once for the walls, then later for the slab floor. The steel has to extend 3 feet into the main wall and 3 feet into the shorter wall beyond the point where the footing starts (Figure 11). When a slab is independent from a perimeter foundation wall, insulation may be installed either on the exterior of the foundation wall or between the foundation wall and the slab.
