Rock Africa - Rockfall Protection

Rockfall protection is a science in itself. Conventional measures have often taken the form of shotcrete, nailing or other slope covers but these only partially address the causes and are never 100 percent effective. They often comprise a hard engineering solution which is also expensive, ugly and environmentally unacceptable in terms of aesthetics, greening and carbon emissions. There are far better solutions available and in this light Geobrugg has been developing rock fall protection systems since 1951 and testing and analysing barrier behaviour since 1981. Today their dynamic barrier systems are capable of absorbing energies up to 5000 kJ which equates to a 16 000 kg rock travelling at 90 km/h. For a short video of the test, please click here.

However in situations where the catchment area is too small, expected rockfall bounce heights and kinetic energies are too high, the use of rockfall barriers is impossible. In such cases, nailing the slope as a stabilising measure in combination with high tensile TECCO™ steel wire mesh can be very effective. In addition, in very hazardous situations where large blocks need to be kept in place the added beef of the SPIDER™ system is eminently suitable for this purpose.
