The weakening of building materials, changes in physical properties and the appearance of deformations lead to a deterioration in the overall performance of the building. In order to avoid such deformations, such a reliable and durable technology as deformation (elastic) seams is used. Thanks to them, a constant resistance of the structure to various physical influences is ensured. Using such a seam, it is possible to exclude the destruction of structures.
Technical operating conditions
An expansion joint is a place in the wall of a house specially provided for this purpose, which ensures the movement of the building relative to the foundation. As a rule, the expansion joint has the form of a closed cavity, which is located along the wall of the structure.
Its dimensions can be varied, however, the minimum width is 15 mm. Such a seam provides compensation for soil shrinkage or temperature changes. Depending on the location, expansion joints are of the following types:
for interior and exterior walls. Such seams perform different functions, for example, they affect the redistribution of loads on the walls of the building, prevent them from shifting, and also provide sound and thermal insulation.
Expansion joints, which are arranged using waterproofing materials, protect building materials from destruction, and the foundation from moisture. Currently, the variety of expansion joints is impressive and everyone can choose an individual option for their project. The correct installation of the structure deserves special attention, since the seam must constantly work. All additional questions can be discussed with representatives of the online store, who will help you make the right choice.
Types of expansion joints
Based on the characteristics of the expansion joint, we can say that it can be: external, internal and through. According to the method of the device, they distinguish:
A keyed expansion joint is arranged during the laying of the foundation. Anchor seam allows you to compensate for soil movements under the influence of temperature conditions. Frame seams are made during the construction of buildings to compensate for wall deformations during shrinkage. With a through device of an expansion joint, the joints between all the walls of the structure are located along its entire height.
