I RANGE OF APPLICATION
The design of rockfall protection systems is based on detailed investigations by specialized engineering firms,
particularly taking into account the following geotechnical aspects to define the range of possible applications:
•
Previous Rockfall events
•
Condition of the rockfall breakout zone
•
Stability assessment of the entire rockfall zone
•
Rockfall frequency
•
Size of the blocks to be intercepted
•
Trajectories and bounce heights of stones
•
Calculation of kinetic energies
•
Positioning of the barrier (considering the local topography)
•
Anchorage 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 FUNCTIONAL EFFICIENCY OF THE BARRIER SYSTEMS
The functional efficiency of the system is based on one-to-one rockfall tests, carried out and tested in accordance
with the guidelines for approval of rockfall protection nets ETAG 027. The one-to-one rockfall tests are carried out
by dropping a block vertically into the middle field of a three-field barrier. The distance between posts is 10 m, and
an impact velocity of 25 m/s is reached. The full-scale test is approved by a notified test body and the European
Technical Approval (ETA) has the number ETA
– 09/0262.
IV QUALITY CONTROL FOR INSTALLATION
This product manual describes in detail the different steps for installation of the barriers. These steps must be
faithfully followed by local contractors.
