About this detail

Concrete slab-on-grade joints feature three-quarter-inch diameter by one-foot six-inch long smooth dowels spaced at twelve inches on center with smooth cut ends. Dowels are held parallel and level by mechanical means, with alternate pipe dowels permitted per ICBO-ES-ER-5934. Exterior slabs receive elastomeric joint sealer, while interior slabs are discontinued at column line control or construction joints without continuing reinforcing. Sawcut control joints are made immediately after finishing operations using soft-cut saw equipment prior to drying shrinkage.
