Rockfall protection can be dealt with in two ways
- by curtain meshing the rock faces
- by catch walling
By curtain meshing the face, spalling rocks can be either held in
place by pinning the mesh to the rock strata or by draping it over
the face guiding the falling rocks harmlessly to the base of the
The mesh facing normally has vertical and/or horizontal cabling
secured to the mesh/rock to provide fixity and integrity to the
jointing of the panels. It is normal to seek advice from specialist
installation companies as to the design of this type of work.
Additional anchoring of large unstable rock masses on the face may
Catch walling rockfall protection is a freestanding gabion wall of
sufficient mass to withstand impact of falling rocks. Location of
the catch wall and height of the wall is important to ensure the
trajectory of the falling rocks will be impacted on or behind the
Rockfall netting or rock netting as it is commonly called are rolls
of wire mesh manufactured using triple twisted PVC coated
galvanised or just plain galvanised wire. Anchored to rock face to
contain rockfalls. Alternatively, use in conjunction with our range
of erosion control mats to help stabilise steep rock faces. One
popular example is our Rock netting and Secumat combination which
was used behind Fitzgerald's Pub in Avoca.
Unlike chainlink mesh, the strong 'triple twisted' mesh rock
netting will not unravel if one of the mesh wires should break.
Rock netting is manufactured from the same mesh that is used for
the manufacture of Woven Mesh Gabions. PVC coated Rockfall Netting
have a design life of up to 120 years. Please check out our Woven
Mesh Gabion page for more technical information.
