Concrete slab on grade joints including control joints, doweled control joints, construction joints, and doweled construction joints bearing on subgrade. Sawcuts extend to one-fourth the slab depth with joint filler installed at sawed joints and a one-eighth inch radius on edges only where the slab is exposed. Doweled joints feature one and one-quarter inch diameter by one foot four inch smooth dowels spaced at twelve inches on center at the mid-depth of the slab with two inch clearance from the edge of the joint. Construction joints incorporate a two-foot zero-inch rebar lap splice.
