Frequently asked questions

Expansion joints are joints designed in buildings to allow for the natural movement of materials due to changes in temperature, humidity, and pressure. These joints are an important part of structural design and have many benefits:

1. Reducing stress: Expansion joints help reduce stresses caused by thermal changes. When materials are exposed to heat, they expand, and when they cool, they contract. These changes can lead to cracks or damage to the structure if not treated properly.

2. Improving durability: By reducing the mechanical stresses that materials are exposed to, expansion joints play a role in improving the durability of the building and increasing its lifespan.

3. Avoiding cracks: Expansion joints help avoid cracks and damage that can occur as a result of the expansion and contraction of materials. This enhances the aesthetics of the building and reduces maintenance costs.

4. Adapting to surface movements: In some cases, expansion joints are necessary to accommodate movements resulting from earthquakes or contraction and expansion resulting from changes in the soil.

5. Weight Distribution: Expansion joints contribute to evenly distributing weights across building components, which helps stabilize the structure.

6. Improving Insulation: In some designs, expansion joints can contribute to better insulation, which contributes to improving the energy efficiency of the building.

Ultimately, expansion joints are an essential element in building design to ensure their long-term sustainability and efficiency.
