Calculate the thickness of the edge of a concrete slab-on-grade floor required to support a wall load. Once I've determined the average grade of the dirt, I can set the finish concrete floor grade up 4, 5, or 6 inches from that, depending on how thick I want my concrete floor. So I have decided to make underground water tank base slab as a footing for column. Floors - Center/Joint Wall Load Calculate the maximum wall load that the maximum wall load that a concrete slab-on-grade floor can support at a joint or at the center/interior of the slab. When, if ever, should you consider installing a continuous layer of rigid foam under a concrete slab? The answer to this question depends on at least four factors: (1) your climate zone, (2) the height of the slab with respect to grade, (3) whether the room above the slab is used for living space; and (4) whether the slab has hydronic heat. Monolithic-slab foundations require a perimeter trench. The top (steel) reinforcement is important.
