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 and the Swiss guideline of type approval of

rockfall barriers in Walenstadt, Switzerland (SG). 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 tests were approved by a notified test body and the European Technical Ap-

proval (ETA) has the number ETA

– 13/0225 and the Swiss testing certificate of the federal office of environmen-

tal (BAFU) with the testing-No. S 13-1.

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.
