Research and development

Since our first avalanche prevention structure was completed in 1951 we have continued to develop better protection systems year after year. We challenge ourselves to constantly improve; therefore our solutions have become the standard.


New FIA Standard: Geobrugg Motorsport Fences first to be homologated

New FIA Standard: Geobrugg Motorsport Fences first to be homologated
FIA (Fédération Internationale de l’Automobile) governing body of the motorsport 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.

Flexible debris flow barriers and their service ability proof
The first research on a serviceability method for scour and erosion issues on flexible debris flow nets. Design and calculation will be more economically and safely, maintenance costs will be minimized and a longer lifetime of the entire barrier system, including anchors as the most cost-intensive parts, can be provided. Impressions of the small field tests.


World's first dimensionable attenuator system
Geobrugg developed together with international experts an attenuator protection solution which can be efficiently dimensioned. This innovative rockfall protection is a modified rockfall drape providing particularly efficient protection. It was presented in British Columbia/Canada in August 2018.

Rockfallbarrier 10000 kJ tested

Rockfall barrier tested for 10'000 kJ
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.



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.


Rockfall barrier certified for 8000 kJ
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) in July 2012.

TECCO® Slope Stabilization System and RUVOLUM® Dimensioning Method
A new special method has been developed for the designing of flexible slope stabilizationsystemswith high tensilesteel wire meshesfor the use on steep slopes in more or less homogeneous soil or heavily weathered loosened rock. Book (pdf)


Motorsport Debris Fences
The Circuit Dijon-Prenois in France was one of the first race circuits where spectators along the race track are being protected by the new Geobrugg Debris Fence.

World Record GBE-5000: Rockfall Barrier
With the GBE 5000 barrier, we certified a new world record according to Swiss FOEN and EOTA.


RXE Rockfall Barriers 500 - 8000 kJ
Our new rockfall barries were 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.


Rockfall barrier
GBE rockfall barriers receive worldwide CE certification in accordance with EOTA and are the first rockfall barrier according to ETAG027.

Debris-Flow Protection Systems for Mountain Torrents Basic Principles for Planning and Calculation of Flexible Barriers


TECCO® mesh
A new complete system consisting of nails, mesh, spike plates and clips to secure the embankment was developed: a high tensile wire mesh with design concept RUVOLUM®. The first tailor-made system with free anchor grid.


ROCCO Ringnets
The ROCCO ring nets of the new RXI rockfall barriers consist of rings of untwisted wire bundles.


First 1:1 rockfall tests

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.


Component testing
First tests in a steel frame with components


First energy disspation elements (brakes) for rockfall barriers
This meant the start for the development of rockfall barrriers with higher energy absorbtion.



Avalanche prevention according to the new guidelines for avalanches
The first engineered avalanche prevention structure with triangular wire rope net - new with modular fields - are designed according to the (then) new guideline of Swiss WSL-Institute for Snow- and Avalanche Research SLF.


1st Avalanche prevention project at Pilatus (Matthorn, near Lucerne)
This barrier is still in use (2019).
