We manufacture bridge bearings, roadway expansion joints, seismic protection devices, vibration dampers and monitoring systems. The crucial factor speaking in favor of MAURER SE: over 1,000 employees working for us worldwide. In this magazine, you will get to know some of them, their projects, their tasks and their professional passions. In face-to-face conversations they describe what particular challenges they have to face in their daily work and how these challenges can be mastered in cooperation with customers, partners and technicians on site. Maybe you have already worked together with one or another colleague or know about projects from his/her area of responsibility. MAURER MAG has been created to provide you – in this first edition and many more to follow – with an overview of and insights into the many facets of our work.

Two earthquakes occurred in 2018, with a particularly severe magnitude of 3.4 on 8 Orhideea Towers, Bucharest January. This does not sound very much, but the earthquakes are a result of natural gas extraction in the Groningen field. The epicenters are not very far from the earth’s surface and the tremors are therefore felt particularly acutely. Even earthquakes of a magnitude of 3 cause damage.
