Expansion Joints:

expansion joints are crucial for managing the natural movement and settling that occurs due to factors like temperature changes, seismic activity, wind loads, and material shrinkage or expansion.Building expansion joints are a critical aspect of construction, helping to maintain the aesthetics, safety, and longevity of structures by accommodating movement and preventing damage that can occur due to various environmental and structural factors.

Control Joints:: Predetermined breaks in concrete or masonry that control where cracking occurs by creating weakened planes. They're typically installed in floors, walls, and ceilings. Expansion Joints: Purpose-built joints that accommodate expansion and contraction in structures, usually filled with compressible material to absorb movement.
Floors:Expansion joints in floors allow for movement due to thermal changes and prevent cracking or buckling.
Walls: Control joints in walls manage stress and prevent cracks from forming. Ceilings: Similar to walls, these joints prevent cracks and manage movement in ceilings.
Flexible Materials: Rubber, neoprene, silicone, or other elastomeric materials are often used in expansion joints to absorb movement.
Metallic Joints: Used in heavy-duty applications or where high load capacity is required. These could be strip seals or sliding plate systems.
