At the required inspection before concealment, a cast-in-place foundation wall has open aggregate voids along its bottom 12 inches and visible reinforcing bar where the approved detail requires concrete cover. No evaluation or repair has been approved. Under 2021 IRC R404.1.3.3.5 and R109.4, what is appropriate?
- AApprove because backfill will hide the area
- BApprove solely after a cosmetic cement-slurry rub
- CApprove solely because standard mix cylinders met specified strength
- Withhold acceptance of the affected work pending evaluation and an approved compliant correction before concealment

Why D is correct
R404.1.3.3.5 requires suitable concrete consolidation, including around reinforcement and embedded items and into form corners. R109.4 requires noncompliant work to be corrected and prohibits its concealment until authorized. The stated voids and missing specified cover require evaluation of the in-place condition and a compliant correction. A favorable sample-cylinder result alone does not establish the required consolidation and cover at that location; neither does hiding it with coating or backfill. The observations do not quantify remaining capacity or establish that every affected wall must be demolished, or that one generic patch can restore every defect.
