Description Movement joints are required in buildings such as airports and shopping malls. These movements are caused by e.g. temperature differences or earthquakes. So far, expansion joint covers and the adjacent floor have had to be removed completely during modernisation. For the first time, the new and innovative MIGUA FSR X allows only the visible surface to be replaced without damaging the adjacent floor. Thus, exchanging the expansion joint cover can be done quickly and cheaply without unoccupancy.
