Expansion joints

Expansion joint (dilatation joint) is intentionally created gap or break in a building's structure, the purpose of which is to separate different building elements. It often appears between a concrete screed and a wall or between two floor slabs in different rooms. Expansion joints are made to prevent stresses, cracks, and other damages caused by factors such as moisture, temperature changes, or ground settling.

For creating expansion joints, round-shaped expansion joint cords are often used, with a diameter tailored to specific applications.

Expansion joints have a structure of closed cells, which prevents them from absorbing moisture and helps them maintain elasticity during long periods of use. They are placed in specially designed slots in floors, walls, or concrete elements. They are used to limit the transfer of stress to the edges of concrete, thus protecting against cracks that may occur when building materials expand and contract due to temperature and moisture changes. Expansion joints are used in industrial facilities, garages, facades, parking lots, and in road structures (bridges, viaducts).

An expansion joint is an element filling expansion gaps that separate individual building elements, allowing the structure to move freely under loads, thus increasing its durability and safety. It is primarily used in expansions of industrial floors (warehouses, production halls, multi-storey car parks), parking surfaces, and road structures (viaducts, bridges), where it reduces stress, limits the penetration of moisture and contaminants. Expansion joints are also used to fill gaps in masonry walls, facades, and technical installations.

Expansion joints are elements filling the gaps with a structure of closed cells. They play a crucial role in the proper functioning of structural joints. The use of expansion joints allows for separating individual concrete elements from each other, enabling each part of the structure to work independently under the influence of dynamic loads, shrinkage, and thermal expansion. Expansion joints eliminate the transfer of stresses to edges, allowing the structure to work freely without the risk of cracks, spalling, or deformations. The closed cell structure of the expansion joint restricts the penetration of moisture and contaminants, effectively protecting the concrete and reinforcement from corrosion and degradation. Filling the gaps with an expansion joint enhances the durability and safety of the structure's use.

At Power Rubber, we offer high-quality expansion joint cords designed to fill expansion joints in floors, parking surfaces, road facilities, and engineering structures. The product is made of material with a closed-cell structure, making it resistant to deformation and moisture penetration. It reduces stress and protects concrete edges from damage. By choosing expansion joint cords from Power Rubber, you are investing in the durability and safety of the structure. A wide selection of cord thickness allows for easy customization to specific applications.
