Storm-Ready Design Project

Stem Walls, Slab, and Reinforcement for Concrete Walls Video

After seven days of steady rain, the crew is ready to pour the concrete for the foundation and slab at the Punta Gorda, Florida, storm-ready home. Bob explains how code now dictates that foundations be elevated and supported by a three-course block stem wall set on reinforced footings below the grade. These perimeter stem walls are reinforced with horizontal and vertical number five diameter steel rods or rebar. The stem walls and slab are poured as one to create a seamless slab and foundation. This integral foundation will protect against water intrusion and hydrostatic prssure that lifts slabs and compromises structures when storm surge comes. The concrete is floated and polished to finish the slab before the reinforcing steel rods and mesh are set for the walls. Vertical steel rods are spliced to the reinforcing rods protruding from the foundation, then steel mesh is attached with wire to the rods. Stirrups and rebar create the headers, and spacers are attached to the mesh to keep it centered in the new wall once the concrete is poured.
