Various methods are used to protect structures from earthquakes. One of them is foundation isolation. 

Seicmic Base isolation  is typically implemented in structures up to 50-60 m in height. It can also be used for taller structures, but this would require minor changes in the system design. The foundation isolation principle is quite simple: a bearing (isolator) is installed on each column of the structure. This system not only absorbs loads generated by an earthquake but also isolates the structure from the ground, which explains the name. When foundation isolation is not used, the structure is designed to be more rigid to withstand seismic loads. However, when using the foundation isolation technique, these loads are absorbed by bearings, eliminating the need to design rigid structures, which ensures significant savings in reinforced concrete. 

In some countries, foundation isolation is a mandatory requirement for certain structures. E.g., in Turkey, seismic foundation isolation is mandatory for all new hospital projects with more than 100 beds. Globally, this system is also being implemented and is usually mandatory for projects such as hospitals, hotels, business centers, airports, etc. MAURER has implemented hundreds of projects using this method worldwide. There are also projects in our country where the foundation isolation has been implemented.
