New RXE-8000 rockfall barrier stops a boulder of 20 metric tons in a free fall of 43 meters in Geobrugg’s test facility Lochezen in Walenstadt/Switzerland – this means world record! Some benchmark data:

– Free falling 43 m = 103 km/h
– Impact energy 8000 kJ
– 8.5 meters barrier deflection
– 85 % residual barrier height
– Almost 100 % height in adjacent field
