Step 2: Frame 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. ICF friendly dimensions take into account the length and height of the ICF forms when designing wall lengths.

Formwork is placed to form the footings. This can be done with lumber or a plastic drainage system like Form-a-Drain.

Horizontal rebar in the foundation should be placed correctly before the footing or foundation is poured. The use of rebar chairs or other methods to ensure rebar is correctly spaced is required. The vertical dowels should extend beyond the top of the footing by at least 20 to 25 inches. That amount may be more depending on the lap requirements, as well as seismic and wind load ratings.
