Footings
When laying out your footings or stem walls, work with ICF friendly dimensions if possible and keep exterior finishes and flooring heights in mind. Plan for elevation changes when laying out step footings. ICF friendly dimensions take into account the length and height of the ICF forms when designing wall lengths.
You’ll also want to level your footings within a ¼ inch or less. After stacking the first two courses, shim and trim the block to level your footings. Be mindful of the fact that blocks will settle slightly when filled with concrete and rebar and leveling footings from the beginning will equal fewer headaches for the rest of the project.
