The German Federal Ministry of Digital Affairs and Transport/mFUND approved research funds of almost 800,000 euros for the smartROCK project. The project deals with BIM methodology (Building Information Modeling) in the natural hazard sector, planning, construction and monitoring of protective structures against rockfall.
The full-scale testing undertaken in cooperation with Holmes Solutions has given a unique insight into the behaviour of ruptured lines (marine). The detailed data gained from this type of testing is key to the success of life-safety products.
Full-scale experiments of rockfall barriers in natural terrain at the Flüela Pass, Switzlerland, 2018 - 2021: Tests with instrumented blocks to quantify how blocks decelerate at barrier impact in real conditions. 25 blocks impacted the barrier which absorbed a total of 12’100 kJ of impact energy. Boulder masses: 840 - 3200 kg.
Since August 2022, the South of the Canton of the Grisons is provided with 31 GUARD devices. The Office for Forests and Natural Hazards Grisons, the Rhaetian Railway RhB and the University of Applied Sciences Graubünden are working together on how to use remote monitoring to efficiently and reliably assess the condition of flexible protective structures.

Attenuator barriers smoothly guide impacting rocks instead of absorbing large amounts of strain energy arresting them. Rock rotation plays an essential role in the bearing capacity. This work describes a numerical modeling and simulation method to support the engineer’s design decision, reinforce test results, and confidently predict barrier performance beyond experimental configurations.
We performed full-scale rockfall tests in natural terrain to study how rockfall barriers absorb rotational and translational energies in realistic conditions. The presented methodologies pave the way to a comprehensive understanding of rock-ground and rock-net interaction, a key requirement to improve the design of flexible barriers that account for the role of rock shape, spin and eccentric impacts in rockfall protection.
FIA (Fédération Internationale de l’Automobile) motorsport's governing body introduced a new standard with performance criteria. The first homologated products are the Geobrugg motorsport fences: the Debris Fence and the Mobile Debris Fence meet the requirements of FIA Standard 3502-2018 debris fence.
SWISS INOX, an association which promotes the use of stainless steel awards Geobrugg and its research partner WITg for their high-tensile stainless steel chainlink mesh.
Together with international experts, we developed an attenuator protection solution that can be efficiently dimensioned. This innovative rockfall protection is a modified rockfall drape providing particularly efficient protection; presented in British Columbia CA in 2018.
RUVOLUM® (launched in 1999), DEBFLOW, SHALLSLIDE or SPIDER® online tools offer new functions, e.g., 3D view, a larger selection of nails, recommended nail inclination, anchor-plate assembly or additional drawings illustrating the acting forces and indicate the crucial parameters.
A world first in the highest energy class, the RXE-10000 rockfall protection barrier was tested in October 2017. It was granted approval number ETA 17/0947 by the European Organisation for Technical Approvals (EOTA) in May 2018.
ETA-certification for RXE-500 rockfall barriers. In 100 kJ to 8000 kJ energy classes, our protection systems are stringently tested and approved in all standard heights. All RXE systems are certified by EOTA and FOEN guidelines, bearing the CE certificate.
Geobrugg widens its product portfolio for slope stabilization: The new TECCO® System with three different wire strengths can now be applied to nearly any slope, regardless of whether it is rock, soil, or anything in between.
A world first in the highest energy class, the RXE-8000 rockfall protection barrier was granted approval number ETA-12/0213 by the European Organisation for Technical Approvals (EOTA).
The Circuit Dijon-Prenois in France is one of the first race circuits where the FIA Geobrugg Debris Fence protects the spectators.
With the RXE-5000 (then GBE) barrier, we certified a new world record according to Swiss FOEN and EOTA.
Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) confirms the effectiveness of our debris flow barriers designed with analytic and numerical finite element models.
Our then new rockfall barries are the first to be FOEN and ETAG27 certified. Because of its capacity for maximum energy absorption, the RXE has set the standard for low deflection levels.
The first barrier to be tested and certified according to Swiss (FOEN) and an EU-European (ETAG27) standards.
To mark its 50th birthday, Geobrugg presents a new record: the first (FOEN) certified rockfall protection barrier.
System for slope stabilization: nails, mesh, spike plates and clips; high tensile wire mesh with RUVOLUM designed — the first tailor-made system with a free anchor grid
Execution of controlled rockfalls for regular rockfall field tests at testsite Oberbuchsiten.
The ring nets of the RXI rockfall barriers are composed of rings of untwisted wire bundles.
The world's first 1:1 rockfall tests with flexible barriers were carried out in California under the leadership of CALTRANS with an RX-type barrier.
First tests in a steel frame with components
Brakes for rockfall barriers meant the start of developing rockfall barriers with higher energy absorption.
This barrier at the Pilatus mountain (Matthorn, near Lucerne, Switzerland) is still in use. Picture: Google Earth.
The Kabelwerke Brugg (now BRUGG Group) develops mesh for the first trials in avalanche prevention.
