When it comes to installing the joints in the edifices, people generally get confused between the expansion and seismic joints. These, no doubt, sound similar but are very different from each other. Let’s get acquainted with the disparity among the two, and know the uses as well as applications of both. Expansion Joints The Expansion Joint, which is many times also known as Movement Joint is a sort of assembly designed to permit the movement of the edifice –that may be caused due to temperature changes. In other words, it can be understood that the expansion joint is the gap in the construction or building made by an architect to absorb the heat-induced contraction or the extension of several construction materials –safely.
Expansion joints are developed to accommodate building movements caused by shrinkage, creep, or temperature changes. These joints can be broken down into three main types – metallic, fabric and rubber. All these types play in holding parts together and absorbing vibrations.
