What is a movement and expansion joint?

04 April 2025

Movement and expansion joints are essential construction profiles designed to absorb material shifts caused by temperature changes, humidity, or natural structural movement. Proper implementation is key to ensuring the durability of buildings, offering the ideal solution to manage these movements without compromising the aesthetics or functionality of surface finishes.

A movement and expansion joint is installed in the gap between two building elements—such as slabs, wall claddings, or floor coverings—and allows for relative movement without causing cracks or structural damage. These joints prevent internal stress in materials, especially in large-scale constructions or those exposed to sudden temperature changes.

Movement and expansion joints for floors

In concrete or ceramic floors, these joints compensate for expansion and contraction, preventing lifting or cracking. They are especially necessary in regions with extreme climates, such as northern Argentina (with high temperatures) or Patagonia (with sharp temperature variations).

Types of movement and expansion joints

  • Aluminum: Ideal for areas with moderate corrosion, such as coastal regions. These lightweight and durable products are designed for public and commercial buildings.

  • 430 Steel: Used in projects that require higher mechanical strength.

  • A Joint Profiles: Perfect for high-traffic floors, allowing the surface to withstand thermal changes without cracking. Ideal for shopping centers, hospitals, and public buildings.

  • Euro Joint Profiles: Designed for projects requiring high mechanical resistance, such as industrial pavements and exterior surfaces exposed to extreme weather conditions.

Common applications of movement and expansion joints

  • Public buildings

  • Industrial pavements and floors (in factories or logistics centers).
