TL;DR
A saw-cut joint is a control joint cut into a curing concrete slab, typically to a depth of one quarter of the thickness, that creates a deliberate weak plane so shrinkage cracking occurs in a straight, sealed line instead of randomly. Timing is critical: on most slabs the cut must happen within 4 to 12 hours of finishing, before internal stresses exceed the concrete's early strength.

On driveways and patios the joints are laid out in panels roughly 8 to 12 feet square.
