The separated elements or their fragments independently bear <strong>anticipated loads, deformations, and displacements<\/strong> caused by various factors, such as:<\/p>\n<ul>\n<li><strong>Temperature changes<\/strong>,<\/li>\n<li><strong>Uneven building settlement<\/strong>,<\/li>\n<li><strong>Shrinkage or expansion of building materials<\/strong>.<\/li>\n<\/ul>\n<h3><strong>Types of Expansion Joints<\/strong><\/h3>\n<p>Expansion joints are categorized into:<\/p>\n<ul>\n<li><strong>Structural Expansion Joints<\/strong> \u2013 Separate sections of a building, forming an independent static system. Used in cases of changes in foundation type, construction layout, large load differences, and extensive horizontal building dimensions.<\/li>\n<li><strong>Thermal Expansion Joints<\/strong> \u2013 Designed to eliminate the impact of large stresses that could cause <strong>thermal deformations<\/strong> due to material expansion, such as in railway or tram tracks.<\/li>\n<li><strong>Technological Expansion Joints<\/strong> \u2013 Counteract <strong>shrinkage or expansion<\/strong> of materials used in construction elements.<\/li>\n<li><strong>Anti-Vibration Expansion Joints<\/strong> \u2013 Reduce or eliminate <strong>vibration effects and shocks<\/strong> between structural elements. Used between machines and their foundations, in flooring under vibrating machinery (e.g., hammers), and in areas prone to <strong>earthquakes or mining damage<\/strong>.<\/li>\n<\/ul>\n<p><strong>The best product for floor expansion joints is Bostik <a href=\"https:\/\/www.sanier.pl\/produkt\/p795_sealnflex_premium\/\">P795 SEAL\u2019N\u2019FLEX PREMIUM.<\/a><\/strong><\/p>\n<h3><strong>When Is an Expansion Joint Used in a Building?<\/strong><\/h3>\n<p>An <strong>expansion joint<\/strong> is a <strong>versatile solution<\/strong> widely applied in <strong>construction and interior finishing<\/strong>.
