In mid-2021, we carried out certification tests for a new rockfall protection barrier. After two obligatory and successfully held tests (service energy level 1 +2), the program is complete - all the standards required here. But the tested barrier still looked too good. The engineers wondered: How many times can we drop the test block into the barrier before giving up? More in the video.
The findings regarding remaining functional capacity are valuable. At Geobrugg, we want to exceed existing standards. Because in nature, not one stone hits the barrier according to a standard.
