Types of Concrete Joints in Buildings

Types of concrete joints in buildings are

  • Expansion Joints
  • Contraction Joints
  • Construction Joints

Expansion Joints

This joint is used in concrete and steel. An expansion joint allows the concrete or steel to expand or contract with daily temperature variations. If you don’t allow this, you may get buckling or spalling or total failures. They are commonly provided in bridges, railway tracks, piping systems, and other structures.

Contraction Joints

A contraction joint is a joint that is put in the concrete to control cracking. Contraction Joints (often confused with expansion joints) are cuts or grooves made in concrete or asphalt at regular intervals.

Construction Joints

A construction joint occurs when there are multiple concrete placements. It can occur between different days of concrete placements.
