12500 kJ tested: The world's strongest rockfall barrier
Geobrugg sets a new benchmark: the RXE-12500 barrier successfully withstood the impact of a 25-ton concrete block traveling at 115 km/h, absorbing over 12,500 kJ of energy — the highest ever recorded in a rockfall protection system.
This achievement not only surpasses Geobrugg’s previous record of 10,000 kJ set in 2017 but also demonstrates a significant step forward in safety and reliability for critical infrastructure in rockfall-prone areas.
In this newsletter, we present the key data from the test, its relevance to natural hazard mitigation, and the main advantages of the RXE-12500 system.
