I AREA OF APPLICATION
Rockfall protection systems are planned on the basis of detailed research carried out by specialist engineering
companies, which take the following geotechnical aspects into account and define the area of application accord-
ingly:
•Previous rockfall events
•Condition of the rockfall outbreak zone
•Assessment of the stability of the entire rockfall zone
•Frequency of rockfalls
•Size of the rocks collected
•Trajectories and displacements of the rocks
•Kinetic energy calculations
•Positioning of the barrier (taking the local topography into account)
•Anchoring conditions
II QUALITY OF THE SYSTEM COMPONENTS
Geobrugg AG, formerly the Geobrugg Schutzsysteme (Geobrugg Protection Systems) department of Fatzer AG,
Romanshorn, has been certified according to the quality management system requirements (ISO 9001:2008) un-
der the registration number CH-34372 since August 22nd, 1995. The certification center is the SQS (Swiss Asso-
ciation for Quality and Management Systems), which is a member of IQNet. The quality manual specifies in full
the way in which the individual system components (basic material, commercial products, and end products) are
checked extensively to eliminate poor quality. You can find the corresponding certificates in the appendix.
III FUNCTIONALITY OF THE BARRIER SYSTEMS
The system functionality is based on rockfall tests that replicate real-life conditions, performed in Walenstadt (SG),
Switzerland, in accordance with the European Guideline ETAG 027 “Falling Rock Protection Kits”. In the rockfall
tests under real-life conditions, the rocks are thrown vertically into the central field of a three-field barrier with a 10
m distance between the posts of each field. An impact speed of at least 25 m/s is achieved. These investigations
are inspected by notified testing centers and obtain European approval, known as ETA (European Technical As-
sessment), as well as a Swiss inspection certificate from the Federal Office for the Environment (FOEN). The cur-
rent system GBE-100A has the inspection certificate no. ETA 17/0279, ETA 17/0283 and Rockfall Protection Net /
