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 standard.

2020

New edition of the TECCO® book
The updated version with new chapters on CE-marking, large field tests, and our dimensioning tool RUVOLUM®. Available as a PDF on geobrugg.com/downloads.

Update TECCO® book in 2020

2019

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.

Prix INOX
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.

Innosuisse project: Rockfall Tests
In order to obtain new measurement data to improve the design of rockfall protection nets and the SLF rockfall simulation programme, SLF researchers and Geobrugg are testing at the Flüela Pass.

2018

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.

Geobrugg Dimensioning Software: Updates
RUVOLUM® (launched in 1999), DEBFLOW, SHALLSLIDE or SPIDER® online tool offer new functions e.g. 3D view, larger selection of nails, recommended nail inclination, anchor-plate assembly or additional drawings illustrating the acting forces and indicate the crucial parameters.

2017

Rockfallbarrier 10000 kJ tested

Smart Barrier Development
Prototype monitoring device for impact acceleration and corrosion

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.

2016

RXE-500 rockfall barrier with ETAG 027 approval
RXE-500 rockfall barrier has become ETA-certified for heights between 3 and 5 meters. In the 100 kJ to 8000 kJ energy classes we offer protection systems stringently tested and approved in all standard heights. All RXE systems are certified both by EOTA and FOEN guidelines and bear the CE-certificate.

2014

TECCO® System
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.

2012

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)

2011

Motorsport Debris Fences
The Circuit Dijon-Prenois in France is one of the first race circuits where the FIA Geobrugg Debris Fence protects the spectators.

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

2010

RXE Rockfall Barriers 500 - 8000 kJ
Our 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.

Debris Flow Design Concept officially accepted
The Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) confirm the effectiveness of Geobrugg's debris flow barriers designed with an analytic model and a numerical finite element model. The Deb-Flow-Design is now used for our debris flow and shallow landslide barriers (VX-, UX and SL-barriers).

2008

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

2001

World record 3'000 kJ
To mark its 50th birthday, Geobrugg presents a new record: the first (FOEN) certified rockfall protection barrier.

1999

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.

1990

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

1989

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.

1987

Component testing
First tests in a steel frame with components

1975

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