One of MAURER's global projects is the seismic protection of the foundations of private residential houses in the Netherlands.
The project was implemented in Groningen, Netherlands. In this area, large-scale gas extraction negatively affected the soil structure. As a result of the voids formed in the rocks, the seismicity of the area increased significantly. About 150 thousand people lived in this area, and before the project was implemented, thousands of houses had already been damaged by earthquakes.
The Dutch government had two ways to solve the problem with residential houses in this area. The first one was to build more durable residential houses or strengthen existing structures. The second way was to seismically isolate the foundations of residential buildings.
The first project was implemented in the second way on the so-called farmhouses. The foundation of the building was isolated from the subsurface, and seismic bearings were installed between them. These SIP-D type bearings allow for structure displacement within 80 mm during earthquakes, absorbing friction energy. As a result, thanks to these bearings, the structure does not perceive vibrations during the earthquake in a dangerous form.
MAURER also installed its seismic monitoring systems in this project.
