Danielsberg

Buildings and the main road into the Mölltal (Danielsberg) were regularly affected by rockfall. During the planning of hazard zones, geological surveys also identified a substantial rockfall risk for the future. The expected rock falls require constructions that can absorb the highest energies.

Various solutions for protecting the infrastructure were considered. An earth dam, for example, was not an option due to the limited space available.

Amongst the flexible rockfall barriers, only the Geobrugg RXE-10000 with an energy absorption capacity of over 10,000 kJ met the requirements in terms of energy absorption capacity. The area occupied by the barrier is relatively small.

This is the first rockfall protection project worldwide with a capacity of 10,000 kJ. The RXE-10000 system was certified in 2018.
