What is an expansion joint?

04 April 2025

Expansion joints are essential profiles in construction, designed to absorb material movements caused by thermal changes, humidity, or natural shifts. Their proper implementation is key to ensuring the durability of structures and provides the ideal solution to absorb these movements without compromising the aesthetics or functionality of coverings.

Movement and expantion joints

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).

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).
