Control Joint vs. Expansion Joint Difference - The Constructor
Expansion joints are placed in concrete to prevent expansive cracks formed due to temperature change. Concrete undergoes expansion due to high temperature when in a confined boundary which leads to cracks. Expansion joints are provided in slabs, pavements, buildings, bridges, sidewalks, railway tracks, piping systems, ships, and other structures.

Expansion and Crack Control Joints - SealGreen
There are two types of joints in concrete slabs, expansion joints and crack control joints. Every concrete slab inside (basements, garages, warehouses) or outside (driveways, patios, entries, walkways, pool decks) are required to have joints every eight feet horizontally and vertically. This blog will try to answer the many questions that people have about driveway expansion joints.
