Filling the expansion joint

Floor expansion joints are a crucial element in building design and construction. Proper planning and implementation of expansion joints can minimize the risk of floor damage and ensure its long-term durability.

The most important information

An expansion joint is a deliberately created gap that prevents uncontrolled expansion and contraction of a material or structure in response to changes in temperature, humidity or pressure.

In construction, expansion joints are used to prevent structural damage and allow for natural movement between individual components. In building structures, expansion joints, such as joints or expansion joints, are used to allow for controlled expansion or contraction of a building without structural damage.

Expansion joints should always be installed and matched to the planned floor covering. Their presence and proper execution prevent cracking and deformation of the materials.

Types of expansion joints

There are several types of expansion joints that are used in different construction contexts.

Here are some of them:

• Structural expansion joints are planned and placed in specific locations to ensure structural flexibility. They can include expansion joints in floors, walls, ceilings, and other structural elements. Structural expansion joints allow for free movement and dimensional changes without the risk of damage.

• Thermal expansion joints are particularly important in large structures, such as bridges and long buildings. They result from temperature differences between individual structural elements, which can lead to changes in the length of the elements. Thermal expansion joints allow for the absorption of these changes by defining spaces where the structure can freely expand or contract.

• Anti-vibration expansion joint - minimizes the impact of vibrations on the structure of buildings.

Types of floor expansion joints

• Perimeter expansion joint refers to a specific type of expansion joint used in flooring, especially at the perimeter of the floor where it connects to other building elements, such as walls, pillars, or other permanent structural elements. Therefore, a perimeter expansion joint is placed along the edge of the floor around the entire perimeter of a room or area.

• Indirect refer to the placement of expansion joints in the subfloor to divide it into smaller, independently functioning sections. This type of expansion joint allows for natural movement and deformation of individual sections of the subfloor, minimizing the risk of cracking and damage.

Expansion joints - protection

Filling expansion joints is an important part of building maintenance and construction. Without proper maintenance and filling, cracks or damage can occur, increasing the risk of serious structural damage. To avoid these problems, special products are used to fill expansion joints. Recommended products are quick and easy to apply sealants. They can be used in areas such as floors, walls, building facades, roofs, and more.

Choosing the right product depends on many factors, the most important of which are:

• the type of material on which it will be applied,
• type of expansion joint,
• weather conditions in which it will operate

We offer specialized products for filling expansion joints that will help you achieve the desired effect quickly and easily.
