Shattered Slab

A shattered slab is a PCC slab that is divided into four or more pieces by intersecting cracks. Shattered slabs are typically the result of overloading, inadequate support, or both. If all pieces or cracks are contained within a corner break, the distress is NOT categorized as a shattered slab; it is instead categorized as a severe corner break .
