Filling the expansion joints

Floor expansion joints are an important element in the design and construction of buildings. By properly planning and implementing expansion joints, you can minimize the risk of floor damage and ensure its long-term durability.

The most important information

An expansion joint is a deliberately made 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 damage to the structure and allow natural movements between individual elements. Expansion elements are used in building structures, such as joints or expansion strips, which allow for controlled expansion or contraction of the building without damaging its structure.

Expansion joints should always be made and matched to the planned floor covering. Their presence and proper execution prevent cracks and deformations of the materials.

Types of expansion joints

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

Here are a few of them:

• Structural expansion joint - This is a expansion joint planned and placed in specific places to ensure the flexibility of the structure. It may include expansion joints in floors, walls, ceilings and other structural elements. Structural expansion joints allow for free movements and changes in dimensions without the risk of damage.

• Thermal expansion joint - This is a type of expansion joint that is particularly important in large structures such as bridges or long buildings. It results from temperature differences between individual parts of the structure, which may lead to changes in the length of the elements. Thermal dilatation allows you to absorb these changes by designating places where the structure can expand or contract freely.

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

Types of floor expansion joints

• peripheral - refers to a specific type of expansion joint used in floors, especially in the border area of ​​the floor, where it connects to other building elements, such as walls, pillars or other permanent structural elements. Therefore, perimeter expansion joints are placed along the edges of the floor around the entire perimeter of the room or area.

• indirect - refers to placing expansion joints in the floor subfloor in order to divide it into smaller, independently working fragments. This type of expansion joints allows for natural movements and deformations of individual parts of the floor underlay, minimizing the risk of cracks and damage.

Expansion joints - protection

Filling expansion joints is an important part of building maintenance and construction. Without proper maintenance and filling of gaps, cracks or damage may occur, which increases the risk of more serious damage to the building structure. To avoid such problems, special products are used to fill expansion joints. The recommended products are sealants that are quick and easy to apply. They can be used in places such as floors, walls, building facades, roofs, etc.

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

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