Expansion joints are construction joints that allow buildings to move naturally due to environmental changes to protect them from damage. They have many benefits, including:

1-Preventing cracks: Allowing buildings to move in all directions due to thermal expansion and contraction to prevent cracks in buildings.
2-Reducing pressure and absorbing vibrations: Expansion joints absorb vibrations and pressures resulting from earthquake movement and dynamic loads on structures.
3-Increasing structural efficiency: Contributing to enhancing the efficiency of structural buildings by making them safe, stable and durable to withstand all different environmental factors.
4-Improving insulation: Joints insulate heat, and fire and water retention properties can be added to ensure safety and security in buildings.
5-Design flexibility: Various forms of expansion joints are available to suit all projects and different finishes.
6-Easy to install and maintain: Joints can be easily installed and fixed, which facilitates maintenance work in the event of damage.
7-Economic cost: Expansion joints are considered an economical solution in construction projects because they protect the building from damage and cracks, which reduces the need for frequent maintenance and increases the building’s expected life.
