When a stem wall is set on a footer, usually several days after the footer is poured, is there any bonding between the footer and the stem wall that prevents lateral movement of the stem wall? I'm asking this question because some form oil for the stem walls was spilled on the footer surface. The inspector said this reduces bond, even though there was a shear key in the footer.
Chemical bond provides little if any resistance to lateral movement between a stem wall and footing. The resistance is largely mechanical through concrete-to-concrete friction, shear keys, or rebar dowels. The effect of form oil is probably inconsequential.
